Tapered roller bearings

The tapered roller bearings mainly bear radial and axial combined loads. The bearing bearing capacity depends on the rolling angle of the outer ring, and the larger the angle, the greater the bearing capacity. This type of bearing belongs to a separate type of bearing. According to the number of columns in the roller body in the bearing, it is divided into single, double and four-row taper roller bearings. The single-row taper roller bearing clearance needs to be adjusted by the user at the time of installation. Double-row and four-row taper roller bearing clearance has been given according to the user's requirements when the product is delivered,without user adjustments.

 

Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.
