Structure for combined needle roller bearings

104 Published by Sep 19,2019

Combination needle roller bearing is a bearing unit composed of radial needle roller bearing, thrust bearing or angular contact ball bearing.combined needle roller bearings compact structure and small volume, high rotation accuracy, can withstand high radial load and certain axial load.And product structure forms, wide adaptability, easy to install.
Structure for combined needle roller bearings:
This kind of combined needle roller bearings has full load of centripetal needle and thrust ball, or with thrust ball, or with thrust cylindrical roller, or with angular contact ball, which can bear unidirectional or bidirectional axial load.Can also be designed according to the user's special structure requirements.

Specific classification and model comparison for combined needle roller bearings
1. Centripetal needle roller and cage components (type K)
2. Needle roller bearing with double locking ring on the outer ring (type NA, type NKI, type RNA, type NK)
3. Single-row needle roller bearing with double guards on the outer ring (type NA, type NKI, type RNA, type NK)
4. Double-row needle roller bearing with double guards on the outer ring (type NA, type RNA)
5. Stamping outer ring needle roller bearing (HK type, BK type)
How to assemble combined needle roller bearings?

combined needle roller bearings
This kind of combined needle roller bearings has low cost and large bearing capacity, and is suitable for bearing structure with limited installation size. The shaft neck surface is hardened as the rolling surface, and the bearing is pressed into the seat hole, without axial positioning.Proper amount of grease should be injected into the bearing before installation. In general, BK type bearing need not be lubricated after assembly for bearing without protruding end of shaft neck. The end face seal plays a sealing role and can withstand small axial swimming
