Durable Roller Ball Bearing Low Noise Double Tapered Roller Bearing

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
