ball bearing threaded rod end bearing

Rod end bearings consist of a plain spherical articulating eye with an external threaded shaft.

These bearings can support a large radial load and a bi-directional axial load at the same time.

The bearing has a spherical inner ring which makes direct contact with the bore surface of the body made of a special bronze alloy.

This offers a smoother rotational and oscillatory motion and can improve wear and loading properties.

Rod end bearings differ in terms of dimensional specifications and special features. Dimensional specifications include design units, bore diameter, major diameter, bearing thickness, housing diameter, overall length, and thread length. English design units include inches (in) and fractions of an inch. Metric design units include millimeters (mm) and centimeters (cm). Bore diameter is the inner diameter (ID) of the bearing bore. Major diameter is the nominal diameter to the top of the threads. Bearing thickness is the length through the bore. Housing diameter is the outside diameter (OD) of the bearing housing. Overall length is the distance from the top of the housing to the end of the shank. In terms of special features, some rod end bearings are self-lubricating or include a lubrication port. Others are corrosion-resistant or equipped with Teflon seals.

The rod-end joint bearing is mainly used as the supporting part with low requirement of concentricity, high working surface pressure and slow swing and rotary motion

Rod end bearing application

Rod end bearing are widely used in hydraulic engineering, metal forming machine, construction machinery, automation equipment, automotive shock absorber, water machinery sluice gate, navigation lock, textile machinery.
