how much do you know about needle roller and cage assembly?

The needle roller and cage assembly (needle bearing) is a self-contained rolling element with a wide spacing of the two guide faces of the cage to precisely guide the needle and maintain the correct position of the needle. This type of bearing is suitable for applications where the shaft and the seat bore can be used as raceways. The shaft and housing bore raceways must be machined to the specified dimensional accuracy and geometric accuracy to ensure high rotational accuracy in the smallest space.

The main structure of needle roller and cage assembly:
Bearing code Structural features
K/KS single row / single row split
