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
