Rod End Bearings

Select by load capacity, shaft/bolt size, misalignment angle, and material; match the inner bore or stud diameter to your shaft, ensure the dynamic/static load ratings meet your forces, and choose materials (steel, stainless steel, or aluminum) and coatings for corrosion resistance and operating temperature

Common types are male-threaded (stud) and female-threaded (housing) rod ends, and versions with spherical plain bearings or PTFE-lined inserts; use male-threaded for easier installation on a shaft end, female when threading into a housing, and PTFE-lined for low-friction, maintenance-reduced motion

Measure the required bore/stud diameter and the thread pitch/standard (metric or imperial) of the mating component, consult load ratings for the size, and confirm clearance for angular movement; supplier size charts typically map part numbers to bore, thread, and load limits

Stainless steel rod ends offer good corrosion resistance for wet or marine environments; carbon steel with zinc or hard chrome plating can suit general use, while high-temperature applications may require heat-treated steels or specialized alloys specified for the operating temperature range

Regularly inspect for play, wear, or corrosion, and lubricate per manufacturer guidance—some rod ends have grease fittings for periodic greasing while PTFE-lined units are often low-maintenance; replace bearings showing excessive axial or radial play

Look for dynamic and static load ratings, permissible misalignment angle, maximum recommended RPM (if provided), and shaft/bore dimensions; these specifications determine suitability for shock loads, continuous motion, and overall safety margin

Rod end bearings vary by size and material; budget options often exist under $50 for small generic steel units, while larger or specialty stainless and high-load designs can cost more, so compare size, material, and rated loads when balancing price and performance
