Double Row Tapered Roller Bearing of Vista's bearing products series

Features and benefits:

High load carrying capacity 

Double row tapered roller bearings are suitable for heavy radial and axial loads. 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 (from the product tables): the larger the value of e, the larger the contact angle.

Axial loads in both directions 

Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload. 

High stiffness 

Double row tapered roller bearings provide a stiff bearing arrangement. 

Low friction 

The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.
