SIZP Threaded Self-Lubricating Rod End Bearing with PTFE Insert

This series is a self-lubricating rod end bearing with internal threads, featuring a streamlined three-piece structure: rod end body, inner ring, and PTFE plastic liner. The rod end body is made of carbon steel with a galvanized surface; the inner ring is made of high-carbon chromium bearing steel, hardened by quenching and then spherically plated with hard chrome to ensure excellent wear resistance. Its design allows for completely maintenance-free operation.
