TAPERED ROLLER BEARINGS

Tapered roller bearing are designed such that their conical rollers and raceways are so that all element of the roller and raceways 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). This construction provides a high capacity for radial loads, axial loads and combined loads. The larger the contact angle, the greater the loading capacity becomes. When a pure radial is placed on the bearing, an induced load in the axial direction is also generated. So these bearings are generally used in pairs opposing each other. Proper running clearance or preload can be obtained by adjusting the distance of the two bearings against one another. Since the inner (cone)and outer (Cup) rings are separable, each ring can be mounted individually, allowing both rings to use tight fitting practices, if desired.

Both metric and inch systems are standardized by bearing series and both systems are widely used. The metric system’s specified in ISO (ISO 355) and JIS B 1512 and the inch system (including J series) is standardized in AFBMA standard.
