NOS Series External Thread Steel-on-Steel Rod End Bearings (SA...P/K)
The NOS Series external thread (male) rod end bearings feature a steel-on-steel metal-to-metal sliding contact surface, providing high rigidity and load capacity. The rod end body is made from carbon steel by pressing and forming, with an eco-friendly white zinc plating for corrosion resistance. The inner ring (ball) is manufactured from bearing steel, hardened and with a hard chrome-plated spherical surface. These bearings can be lubricated through a grease nipple or via the rod end eye. Available in bore sizes from 3mm to 20mm with metric external threads, the NOS Series is widely used in linkages, actuators, agricultural machinery, and general mechanical systems. For left-hand thread, add "L" suffix to both bearing number and thread mark, e.g. NOSL 10 M10. Stainless steel versions are available by adding "R" prefix to the bearing number when ordering.
