K Series radial needle roller and cage assembly

K Series radial needle roller and cage assembly

This assembly is suitable for applications where the shaft and housing bore can serve as raceways. The raceways of the shaft and housing bore are machined to the specified dimensional accuracy, geometric accuracy and hardness, ensuring high rotational accuracy. The radial needle roller and cage assembly is a special rolling element assembly in which the needle roller is guided by the cage. This assembly occupies minimal radial space and carries high radial loads, making it the optimal choice for applications where radial space is limited.
