Tapered roller bearings consist of four basic components including the inner ring , the outer ring, tapered rollers, and a cage (roller retainer). 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.
Taper roller bearing could used in automobiles, high-precision machine tool, high-frequency motor, centrifuge, gear spindle, agriculture, construction and mining equipment, various axle systems, conveyance vehicles, gear box, engine motors, reducers etc.
Single row tapered roller bearings
Single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle, which is usually between 10° and 30°, is related to the calculation factor e: the larger the value of e, the larger the contact angle.
Matched tapered roller bearings
The assortment of matched single row tapered roller bearings is based on popular sizes of single row tapered roller bearings. Depending on the application requirements, matched tapered roller bearings are available in different designs and variants:
matched bearings arranged face-to-face
matched bearings arranged back-to-back
matched bearings arranged in tandem
