Deep groove ball bearings

• The most popular types among rolling bearings, widely used in a variety of industries.
• Radial load and axial load in both directions can be accommodated.
• Suitable for operation at high speed, with low noise and low vibration.
• Sealed bearings employing steel shields or rubber seals are filled with the appropriate  volume of grease when manufactured.Angular contact ball bearings

  Self-aligning ball bearings

  • Bearing rings and balls possess their own contact angle that is normally 15, 30 or 40.
    Larger contact angle — higher resistance against axial load
    Smaller contact angle — more advantageous for high-speed rotation
  • Single-row bearings can accommodate radial load and axial load in one direction.
  • DB and DF matched pair bearings and double-row bearings can accommodate radial load and axial load in both directions.
  • DT matched pair bearings are used for applications where axial load in one direction is too large for one bearing to accept.
  • Angular contact ball bearings are used for high accuracy and high-speed operation.
• Spherical outer ring raceway allows self-alignment, accommodating shaft or housing deflection and misaligned mounting conditions.
• Tapered bore design can be mounted readily using an adapter.Cylindrical roller bearings
• Since the design allowing linear contact of cylindrical rollers with the raceway provides strong resistance to radial load, this type is suitable for use under heavy radial load and impact load, as well as at high speed.
• N and NU types are ideal for use on the free side: they are movable in the shaft direction in response to changes in bearing position relative to the shaft or housing, which are caused by heat expansion of the shaft or improper mounting.
• NJ and NF types can accommodate axial load in one direction: and NH and NUP types can accommodate partial axial load in both directions.
• With separable inner and outer ring, this type ensures easy mounting.
• Due to their high rigidity, NNU and NN types are widely used in machine tool spindles. Tapered roller bearings
• Single-row bearings can accommodate radial load and axial load in one direction, and double-row bearings can accommodate radial load and axial load in both directions.
• This type of bearing is suitable for use under heavy load or impact load.
• Bearings are classified into standard, intermediate and steep types, in accordance with their contact angle.
• The larger the contact angle is, the greater the bearing resistance to axial load.
• Items sized in inches are still widely used.  Spherical roller bearings

  Needle roller bearings

  • Spherical roller bearings comprising barrel-shaped convex rollers, double-row inner ring and outer ring are classified into three types: R(RR), RH(RHR) and RHA, according to their internal structure.
  • With the bearing designed such that the circular arc center of the outer ring raceway matches with the bearing center, the bearing is self-aligning, insensitive to errors of alignment of the shaft relative to the housing, and to shaft bending.
  • This type can accommodate radial load and axial load in both directions, which makes it especially suitable for applications in which heavy load or impact load is applied.
  • The tapered bore type can be easily mounted/dismounted by using an adapter or withdrawal sleeve.
• In spite of their basic structure, which is the same as that of NU type cylindrical roller bearings, bearings with minimum ring sections offer space savings and greater resistance to radial load, by using needle rollers.
• Bearings with no inner rings function using heat-treated and ground shafts as their raceway surface. Thrust ball bearings
• This type of bearing comprises washer-shaped rings with raceway groove and ball and cage assembly.
• These bearings cannot accommodate radial loads.Spherical thrust roller bearings
• This type of bearings, comprising barrel-shaped convex rollers arranged at an angle with the axis, is self-aligning due to spherical housing washer raceway; therefore, shaft inclination can be compensated for to a certain degree.
• Great axial load resistance is provided.
  This type can accommodate a small amount of radial load as well as heavy axial load.for more koyo bearing cross reference  koyo bearings

I believe that majority people have heard of  NTN self-aligning ball bearings before, now I am honored to make a detail introduce of it.

The outer ring raceway of NTN self-aligning ball bearings forms a spherical surface whose center is common to the bearing center. The inner ring of the bearing has two raceways. The steel balls, cage, and inner ring can rotate freely at a certain angle, as it is stated that the bearings have self-aligning features. Acco rdingly, misalignment of the bearing shaft due to the machining and installation of the shaft and housing will be automatically adjusted. The allowable misalignment angle of the bearing is about 0.07 radian (4) in the case of o rdinary loads (equivalent to 0.09 Cr). However, this angle is also limited by the structure around the bearing which may cause contact with the bearing under misalignment. It is easy to dismount the bearing if an adapter is used. These adapters are widely used fo r transmission or driving equipment, etc. However, since the axial loading capacity is limited, the bearings are not suitable for applications with heavy axial loads.

Now NTN self-aligning ball bearings have been popular in many countries of the world such as Southeast Asia, Middle East, Hong Kong, Europe and United States, Africa and so on, winning good reputation both at home and abroad. The following are some of NTN self-aligning ball bearings sold well in the bearing market:

Being one of the world authorized NTN tapered roller bearings distributor, China BRG bearing is very famous for its NTN products, especially NTN tapered roller bearings.

NTN tapered roller bearings are designed such that their conical rollers and raceways are arranged so that all elements of the roller and raceway cones meet at a common apex on the bearing axis. The rollers are guided by the contact between the large end of the roller and the rib on the inner ring (cone). Both metric and inch systems are standardized by bearing series and both systems are widely used. The metric system is specified in ISO (ISO 355) and JIS 1512, and the inch system (including J-series) is standardized in AFBMA standard.

Besides, by suitably setting the contact condition of the rollers with the raceway ring, not only is edge loading prevented, a certain misalignment between the inner and outer rings caused by mounting erro rcan be permitted. The allowable misalignment fo rNTN tapered roller bearing is about 0.0005 radian (0°, 1.5′) fo rsingle row orback-to-back arrangement and 0.001 radian (0°, 3.5′)  fo rface-to-face arrangement. When a larger misalignment is required by the bearing, please consult with NTN.

Cylindrical roller bearings with cage(fag bearings)
Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers coming into contact with each other during rolling.

The cylindrical roller bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with suffix E have a larger roller set and are thus designed for extremely high load carrying capacity.

The bearings can be taken apart and can therefore be fitted and dismantled more easily. Both bearing rings can therefore have an interference fit.

Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.

Low-friction cylindrical roller bearings
Low-friction cylindrical roller bearings LSL and ZSL are single row, self-retaining and correspond to dimension series 23. The bearings have solid outer rings with two ribs, while the inner rings have one rib. The inner ring can be removed and this gives easier fitting of the bearings. Disc cages or spacers prevent the cylindrical rollers coming into contact with each other during rolling.

High precision cylindrical roller bearings
Cylindrical roller bearings of this type are double row precision bearings for machine tools. They allow radially rigid, high precision bearing arrangements and are mainly used for the radial support of main spindles.

The bearings comprise solid outer rings without ribs, solid inner rings with three ribs and cylindrical roller and cage assemblies with solid brass cages. For optimum setting of the radial internal clearance, the inner ring has a tapered bore with a taper of 1:12. The cylindrical roller bearings can be dismantled and are therefore easier to fit and remove. Both bearing rings can therefore have an interference fit.

Full complement cylindrical roller bearings(ina bearings)
Full complement cylindrical roller bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, high rigidity and are suitable for particularly compact designs. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings and in single and double row designs.

Cylindrical roller bearings with snap ring grooves
Cylindrical roller bearings with snap ring grooves are full complement, self-retaining units comprising solid inner and outer rings, rib-guided cylindrical rollers and sealing rings.

The outer rings have grooves for retaining rings. The inner rings are axially split, 1 mm wider than the outer rings and are held together by a steel strip that is rolled into place.

Locating bearings

Cylindrical roller bearings with snap ring grooves are locating bearings. These bearings are highly rigid and can support axial forces in both directions as well as high radial forces.

Due to the full complement design of these bearings, they have the largest possible number of rolling elements and thus extremely high basic dynamic and static load ratings. Due to their kinematic conditions, however, they cannot achieve the high speeds that are possible when using cylindrical roller bearings with cage.

Bearings for cable sheaves

Due to the grooves in the outer ring, the bearing rings can be axially located with ease. The bearings are therefore very suitable in bearing arrangements for cable sheaves.

Aligning needle roller bearings,Combined needle roller bearings and Inner rings. most of the ina needle roller bearings we can surply in stock .

Needle roller bearings with ribs

Needle roller bearings are single or double row units comprising machined outer rings with ribs, needle roller and cage assemblies and removable inner rings. The bearings are available in open and sealed versions.

Needle roller bearings without ribs

Needle roller bearings without ribs are single or double row units comprising machined outer rings without ribs, needle roller and cage assemblies and removable inner rings.

The bearings are not self-retaining. This means that the outer ring, needle roller and cage assembly and inner ring can be fitted independently of each other.

Aligning needle roller bearings

Aligning needle roller bearings are units comprising drawn outer cups, plastic support rings with a concave inner profile, outer rings with a spherical outside surface, needle roller and cage assemblies and removable inner rings.

The bearings can compensate static shaft misalignments and can thus tolerate misalignment of the shaft relative to the housing.

Aligning needle roller bearings are firmly seated in the housing bore. The bore can therefore be produced easily and economically.

Combined needle roller bearings

Combined needle roller bearings are units comprising radial needle roller bearings with a rolling bearing component capable of supporting axial loads.

Inner rings

Inner rings are made from hardened rolling bearing steel and have precision machined or ground raceways.

They are used where:

the shaft cannot be used as a raceway with needle roller and cage assemblies, drawn cup needle roller bearings with open ends, drawn cup needle roller bearings with closed end and needle roller bearings
needle roller bearings must be combined with wider inner rings in order to facilitate axial displacement of the shaft in relation to the housing
optimum running surfaces are required for the seal lips.

Inner rings, precision machined

In inner rings IR, the raceway is precision machined. Chamfers on the end faces allow easy insertion into the bearings and prevent damage to the seal lips of the bearings. The inner rings are available with and without a lubrication hole.

Inner rings, ground

In inner rings LR, the raceway is ground. The end faces are turned and the edges are broken. These rings have larger tolerances than the rings of series IR. They are therefore suitable for applications that permit larger tolerances for width and less demanding requirements for axial runout.
