SA..C Series Male Rod End Bearing is a high-precision metric rod end bearing with external thread structure, integrating premium spherical plain bearing rod end and self-lubricating rod end technology. Designed with optional 2RS sealing, it is widely used as a reliable hydraulic cylinder rod end and ideal male thread rod end bearing for precision machinery and automation equipment.
The SA..C Series Male Rod End Bearing (SA..C / SA..ET 2RS) is a heavy‑duty metric rod end bearing with external threads, available in left-hand (LH) or right-hand (RH) configurations. This professional male thread rod end bearing adopts a high-performance self-lubricating rod end structure with PTFE composite sliding pair, paired with a built-in spherical plain bearing rod end for stable angular movement and high load capacity.
For sizes with bore diameter d ≥ 35, this series is equipped with 2RS sealed rod end design to effectively block dust, moisture and impurities, ensuring stable operation in harsh working environments. The SA..C Series Male Rod End Bearing features high-strength bearing steel ball (HRC 58‑62), hard chrome plating, and environmentally friendly zinc-plated rod end body, delivering excellent wear resistance and corrosion protection.
As a reliable hydraulic cylinder rod end and key linkage component, this metric rod end bearing provides maintenance-free performance, smooth transmission and high precision, perfectly meeting the requirements of automated production lines, precision instruments, construction machinery and hydraulic systems.
