Roller needle roller bearings are characterized by a thin stamped and formed outer ring

Characteristics of roller needle roller bearings of Changzhou Taiyada Bearing Co., Ltd.:

1. The section height is very low and the load bearing capacity is high.

2. It is mainly used for the bearing configuration with compact structure and low price, and the inner hole of the bearing box cannot be used as the raceway of the needle roller cage assembly.

3. It adopts interference static fit and does not need axial fixing device. Even under high-speed and heavy-load conditions, it can ensure its flexible working performance.

4. Drawn cup needle roller bearings generally do not have an inner ring. Where the journal cannot be hardened and ground, a dedicated inner ring can be used.

5. The outer ring of the hardened steel plate of the drawn cup needle roller bearing and the needle roller cage assembly cannot be separated.

6. The bearing generally adopts single row design. Except for the wider specifications of bearings 1522, 1622, 2030, 2538 and 3038, which are equipped with two needle roller cage assemblies.

7. According to user needs, all single row drawn cup needle roller bearings with shaft diameter greater than or equal to 7mm can be equipped with outer rings with lubricating oil holes (code suffix AS1).

8. The advanced principle of drawn cup needle roller bearings is that the volume of grease in the body is large, and it can be without lubrication for a long time. Due to the high temperature lubrication interval, it can ensure long-term worry-free operation.

9. Generally, single row drawn cup needle roller bearings do not have lubricating holes while double row bearings have lubricating holes.
