Double Row Tapered Roller Bearings High Precision Roller Bearings
The double row taper roller bearing is mainly used to support the combined load which is mianly consisted of radial load. It can restrict the axial displacement of the shaft or housing in the two directions and thus can be used as a bidirectional locating bearing.
Material:
100Cr6, GCr15
Advantages:
- 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.
Application:
- Heavy-duty gear drives
- Various industrial configurations
