Many customers pay much attention to the selection and maintenance of casters, but they often overlook the bearing, which is one of the important components of casters. The normal use of casters is inseparable from the assistance of bearings. Today, Globe Caster will take you to learn about the various forms of fixing the inner ring of caster bearings.

(1) The inner ring of the caster bearing is fixed by the withdrawal sleeve: the clamping method of the withdrawal sleeve is the same as that of the adapter sleeve. However, because of the special nut, the caster withdrawal sleeve is easy to install and unload, and it is suitable for fixing the double row spherical bearing with large radial load and small axial load on the optical axis.

(2) The inner ring of the caster bearing is fixed with an end thrust washer: the inner ring of the bearing is axially fixed by the shaft shoulder and the shaft end retaining ring. The shaft end retaining ring is fixed on the shaft end with screws. The fixing screws should have anti-loosening devices. It is suitable for occasions where the shaft end is not suitable for thread cutting or the space is restricted.

(3) The inner ring of the caster bearing is fixed with an adapter sleeve: the radial size of the inner hole of the adapter sleeve is compressed and clamped on the shaft to realize the axial fixation of the inner ring of the bearing.

Choosing a suitable caster bearing inner ring fixing form is very important to the normal use of the caster. Globe Caster reminds you not to ignore the importance of the use of caster-related accessories and accessories.
