911 553 101 0 WABCO Twin Cylinder, Air Compressor

This high-strength twin cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy-duty braking systems. Designed with a dual-cylinder architecture and a water-cooled configuration, it ensures optimal thermal management during intensive operation in heavy commercial vehicle applications.

911 553 101 0 is the OE-equivalent of the WABCO 911 553 101 0 Twin Cylinder, Air Compressor used in WABCO systems. This component features a precise Ø85.00 mm cylinder bore and a 56 mm stroke to maintain high-performance air delivery standards required by professional workshop technicians.

The assembly includes an M26x1,5 air inlet and outlet port along with an M12x1,5 air unloader port for seamless integration. Maintenance teams should ensure the water inlet and outlet ports (M16x1,5) are properly connected to the cooling circuit to maintain the integrity of the water-cooled valve plate and the ESS feature functionality.

Regular inspections of the through-drive mechanism and the air ports are recommended during routine service intervals to ensure peak system reliability. This part is specifically designed for professional heavy commercial vehicle maintenance and long-term durability in demanding environments.
