POS Series External Thread Rod End Bearings
The POS Series external thread rod end bearings are designed with a steel-on-bronze sliding contact surface for reliable performance under moderate loads. The rod end body is manufactured from carbon steel with an eco-friendly white zinc plating for corrosion resistance, while the inner ring (ball) is made from bearing steel with a hard chrome-plated spherical surface. An embedded bronze liner provides smooth articulation and good wear resistance. These bearings can be lubricated through a grease nipple or directly via the rod end eye, and offer good axial load capacity. Available in bore sizes from 5mm to 30mm with metric external threads, the POS Series is widely used in linkages, actuators, agricultural machinery, and general mechanical systems. Stainless steel versions are also available upon request by adding an "S" prefix to the bearing number.
