Description

Material
Housing plastic
Raceways ball bearing steel.
Balls steel.
Note
Self-aligning and sealed both ends. These bearings comprise a highly precise die-cast plastic carrier in which the bearing steel, clipped-on raceways are mounted. The plastic carrier also acts as a return and seal retainer. The seal is made from a special polyamide material with a low coefficient of friction. The linear ball bearing is secured using DIN 471/472 circlips.
Application
Suitable for applications where installation space is limited.
