Product Details
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.
Double row taper roller bearings have a small number of parts and
high stiffness, and are easy to be mounted and dismounted,
therefore, they are usually used in the applications with changes
loads, such as reducers and coiling machines. The radial and axial
clearance can be adjusted by changing the width of spacer between
two inner rings.
Our double row tapered roller bearings are produced in two
configurations and in several different designs:
The performance of type TDO bearing is the same as two single-two
tapered roller bearings in back to back mounted.
Type TDI bearing is mainly used in roll necks with medium loads.
This type of bearings have a cup spacer, and the clearance is
asjustable.
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. - Long service life
- Enhanced operational reliability
Optimized surface finish on the contact surfaces of the rollers and
raceways supports the formation of a hydrodynamic lubricant film.
Application:
- Heavy-duty gear drives
- Various industrial configurations
