With manufacturing plants throughout the world, NTN is a leading bearing supplier to both the industrial and automotive markets. Founded in 1918, NTN has long been recognized for the most stringent quality standards in the industry and counts some of the most recognized industrial and automotive brand names as its customers.

Deep Groove Radial Ball Bearings

Made from hardened, alloy steel in both conrad type and maximum capacity designs. The series features a close balance between dimensions of bore and OD, and load capacity. This, and their availability with any combination of shields, seals (contact and non-contact), and snap rings make them a popular choice in a broad range of applications.

Several tolerance grades and cage designs are available to best suit the running precision and speed requirements of your applications.

Mainly designed to carry radial loads but able to withstand moderate thrust loads and combinations thereof. Also available is a self-aligning, double row ball design for applications where shaft alignment is a problem.

Series: 6000, 6200, 6300, 6900, 60, 67, 68, R, RA, 1200, 1300, 2200, 2300

Size Range: 10 mm to 320 mm OD.

Cylindrical Roller Bearings

Series: N, NF, NJ, NN30, NU

Designed for heavy radial loads, however can tolerate light or intermittent thrust loads. Speed capabilities comparable to ball bearings.

NTN-Bower’s case carburized ISO E-Types offer 1.4 times the life of conventional E-Types.

For high speed applications, machined brass cages are used. Super precision double-row bearings are also available with close tolerances; ideal for use in machine tool spindles, etc. Sized from 0.7874″ (20 mm) inside diameter to 22.8346″ (580 mm) outside diameter.

Tapered Roller Bearings

Inch and metric sized tapered roller bearings are designed to carry maximum combinations of radial and thrust loads simultaneously.

ET (Endurance Tapered) bearings use a high quality carburized steel and unique heat-treating process to greatly increase durability and extend life span.

4T bearings are manufactured from a special grade of case hardened steel and heat treated for maximum useful life.

Sized from 0.6250″ (16 mm) inside diameter to 10.1250″ (257 mm) outside diameter. Metric ISO sizes from 15 mm inside diameter to 160 mm outside diameter.

Both NTN and NTN-Bower brand names are available.

Spherical Roller Bearings

Spherical roller bearings are self-aligning bearings designed for heavy radial loading. They automatically compensate for large angular errors (shaft misalignments).

Small Type C bearings are widely applicable for small size machines and are suited for both radial and axial loads.

Standard Type B bearings provide ideal contact pressure under radial or combined radial and axial loads, and perform well under high speeds.

Type UA bearings are designed to provide increased life and are ideally suited for heavy, shock or vibratory types of radial loading (i.e. Shaker screens).

Available with cylindrical or tapered bores. Sized from 1.378″ (35 mm) inside diameter to 71.6535″ (1820 mm) outside diameter.

Series: 21300, 22200, 22300, 23000, 23100, 23200, 23900, 24000, 24100, 22200UAVSI, 223UAVSI

Needle Roller Bearings

Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity and lower inertia forces that facilitate size and weight reductions in machinery. Designed to withstand oscillation, perform under severe conditions and interchange with sliding bearings.

Diverse types of needle bearings are available in a wide variety of sizes and tolerances for a multitude of applications.

Needle roller and cage assemblies are offered in single/double row, solid/split cage, metric and inch sizes; as well as connecting rod bearings for special applications. Single and double row bearings are available with/without ribs, and with/without inner rings. Thrust bearings are offered in single row roller and cage assemblies. Yoke and stud type track rollers are available.
