NHS Rod End Bearing is a documented maintenance-free series for industrial linkage or pivot applications. Maintenance-free PTFE composite liner; female metric thread. Use the main image for identification and the full product description for model-by-model dimensions and load data.
NHS is a compact maintenance-free female-thread rod end. Instead of a serviceable bronze liner, the spherical outer race uses a PTFE composite sliding layer and the rod body is pressed around the inner ring. Sizes begin at a 3 mm bore and continue through 25 mm, which makes this family particularly useful in smaller linkages.

Use the dimensional drawing to check wrench flats, center height and the surrounding fork before deciding that two same-bore rod ends are interchangeable. Then review dynamic and static ratings together with the real duty cycle.
No routine grease point is required on the NHS design.
NOS provides the male-thread version; SI T/K is another maintenance-free female-thread family with a steel/PTFE contact system; GE C removes the threaded housing for direct installation in a bearing seat.
