This Bearing could be coated with different kind of color, it could be their original color, it could be coated with silver, Copper, Black etc. which is decided by customer’s market needs and motocycle requests.

When you design this bearing, you need to be very careful on the needle roller tolerance, as instead of shaft, this bearing was insert with the pin instead, sometimes if the roller outer diameter is big, the pin could not go through the hole, and also GJP focus a lot on the both end of needle roller and the slot process, as we need to make sure the roller could move up and down in the cage slot freely and not fall down.

For the replacement market, some customer buy the cage and needle rollers separately, so that they could repair at their most conveniently.

This GJP needle roller and cage assembly bearing is popular used in the big end of connecting rod on the motor model Hero Honda.
