INA K45X50X32-TV/0-7 滚针保持架组件

Overview

INA K45X50X32-TV/0-7 Needle Roller Cage Assembly is an ultra-light radial load element consisting only of needle rollers and a cage, without inner or outer rings. It uses adjacent components as raceways, making it ideal for gears, connecting rods, and compact drives needing high load capacity in minimum radial space.

The cage guides needle rollers at uniform spacing, while the shaft and housing bore act as raceways. Hardness, surface finish, and geometrical accuracy of these mating surfaces determine bearing performance.

Selection guidance

Verify raceway hardness and finish of shaft and housing, lubrication, cage material, load, and speed.
