SKF tapered roller bearings have various types and sizes to suit a wide variety of applications. These can be classified as follows：
– single row tapered roller bearings
– paired single row tapered roller bearings
– double row tapered roller bearings
– four-row tapered roller bearings.
SKF tapered roller bearings have the logarithmic contact profile that provides optimum stress distribution over the roller/raceway contacts. With tapered inner and outer ring tracks, tapered rollers are arranged in the SKF tapered roller bearings. The guide flange with special design of the sliding surfaces and large roller ends considerably promote lubricant film formation in the roller end/flange contacts，which not only increased operational reliability but also reduced sensitivity to misalignment. In addition,if the conical surfaces were extended, the projection lines of all the tapered surfaces converge towards the same point on the axis of rotation. Their design is particularly suitable for the modulation of combined (radial and axial)loads. The axial charge capacity of the bearings，to a huge extent, is determined by the contact angle α; the larger α , the greater the axial charge capacity. What’s more,the α is ralated to an important calculation factor e which indicating an order of magnitude for this angle: the larger the value of e, the higher the contact angle,at the same time ,the higher the axial loads eligible capacity.
