Detailed Product Description
FreeRun is a specialized manufacturer of Thrust Ball Bearing .
Features :
Thrust ball bearings consist of two precision washers (rings) and a ball complement spaced
by retainer. They can besupplied with or without radius ball grooves in the rings. Thrust ball bearings are used under purely axial loads, and its speed is limited.
According to the capability it falls into Single Direction Thrust Ball Bearings and Double Direction Thrust Ball Bearings,
our thrust ball bearings are the particular type of the Single Direction Thrust Ball Bearings.
Single Direction Thrust Ball Bearings
Single direction thrust ball bearings have two washers, with grooved raceways. The curvature of the raceways is slightly larger than that of the ball. Out of two washers, one is shaft washer & the other one is housing washer. The bore of the shaft washer isof the shaft dia & the bore ofthe housing washer is slightly larger than that of shaft washer, to facilitate free rotation. These
types of thrust bearings are mainly used where axial load conditions are too large to be
accepted by radial bearings. They can accept purely thrust load in single direction & they are
not suitable for speed applications.
The thrust ball bearings are separable so that mounting is simple as the washers and the
ball and cage assembly can be mounted separately.
Applications:
RC models, Automotive, electric motors, home appliances,
construction machinery, transmission shafts, gear shafts,
pups, Bicycle and various kinds of professional machinery.
