Air Cylinder Kit
SAF-Holland

Air cylinder kit supplies the actuator assembly for typical air‑actuated locking and release systems on heavy‑duty fifth wheels. The kit includes a cylinder, seals, pistons, and mounting hardware to restore reliable push/pull action that positions the locking jaws and ensures secure engagement. The benefits include consistent release force, reduced operator effort, and predictable clamping performance under varying trailer loads and ambient temperatures. Proper functioning of the air cylinder is critical to preventing partial engagement and unintended uncoupling, especially in windy or uneven road conditions. The VMRS code 059-001-002 provides traceability for maintenance planning and inventory management, while the category classification supports compatibility with standard air‑actuated fifth wheel assemblies. This kit is a practical solution for fleets seeking to refurbish aging locking mechanisms, minimize downtime, and maintain safe, repeatable coupling across a wide range of trailer configurations and operating environments.
