Product Introduction
The AZ9231340317 Rear Wheel Oil Seal Seat Spacer Ring is designed for SINOTRUK HOWO AC16 rear drive axle wheel hub assemblies. Installed between the wheel hub oil seal seat and axle components, it helps maintain accurate installation clearance and ensures stable positioning of the oil seal assembly.
This version is supplied without O-ring, making it suitable for specific AC16 axle configurations requiring separate sealing solutions. Manufactured from high-strength steel with precision machining, it offers excellent wear resistance and dimensional stability under heavy-duty operating conditions. AC16 axle wheel-end systems commonly use dedicated spacer rings and oil seal seat components to maintain lubrication and prevent leakage.
