NOS Series Male Rod End Bearing Description

The NOS Series (external thread) is a maintenance-free rod end bearing with an extruded body. The rod end body is manufactured using a cold extrusion process, offering higher strength, better precision, and lighter weight compared to traditionally machined rod end bodies. It is equipped with left-hand or right-hand threads and adopts a steel/PTFE composite sliding pair. The rod end body is made of medium carbon steel with environmentally friendly zinc plating, and the ball is made of heat-treated bearing steel with hard chrome plating. The maintenance-free self-lubricating design eliminates the need for grease injection. The extrusion process ensures a compact structure and high rigidity. Specifically designed for light-medium load, high-precision, and low-maintenance linkage scenarios in automated equipment, it is compatible with small to medium metric sizes, serving as a core precision connector for automated equipment.

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., NOS 18 L.
The rod end body is manufactured by the extrusion forming process.
