Product Description

Product Description

Cam Follower Stud Type Track Rollers Needle Roller Bearing
(bolt bearings, cam bearings, curve roller needle
bearings, roller bearings, roller needle bearings) are mainly
bearing units composed of a bolt shaft, thick-walled outer ring
and other bearing components. The thick-walled outer ring of the
curve roller can withstand impact loads and reduce deformation and
bending stress. The outer working surface of the thick-walled
outer ring is designed with a circular arc, mainly to avoid stress
concentration, but it can provide a curved roller with a
cylindrical (straight line) working surface for specific
applications. The bolt shaft can be equipped with a hexagonal nut
to quickly and easily install the bearing to the corresponding
machine part. Curved rollers are mainly suitable for track
transmission and other mechanical equipment.
main feature:

Withstand impact load, reduce deformation and bending stress;
The bolt is the shaft, and it is easy to install with the nut;
Diversified structure, wide range of applications
