911 553 007 0 SP1 WABCO (without gear), Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure within heavy commercial vehicle braking systems. Featuring a robust water-cooled design, it utilizes a dual-cylinder configuration with a Ø85.00 bore and a 56 mm stroke to maintain optimal air output. The integration of high-strength components ensures the unit can withstand the rigorous cycles of heavy-duty transport operations.

911 553 007 0 SP1 is the OE-equivalent of the WABCO 911 553 007 0 SP1 air compressor used in WABCO systems. This part is designed for precise integration into the vehicle's air supply network, ensuring that the compressed air delivery remains stable under various load conditions. The unit features a through-drive design and includes an ESS feature for enhanced system stability.

For workshop technicians, installation requires attention to the specific port sizes: the air inlet port is Ø30, the air outlet port is M26x1,5, and the water inlet/outlet ports are M16x1,5. Regular maintenance of the cooling lines and checking the air unloader port (M12x1,5) is essential to prevent overheating and ensure the longevity of the compressor assembly. Always verify compatibility with existing pneumatic layouts before installation.

Maintaining a reliable air supply is critical for the safety of heavy commercial vehicles. This component's water-cooled valve plate and optimized swept volume of 636cm³ help prevent thermal degradation during extended operation. By utilizing this high-grade replacement, fleet managers can ensure that the braking system receives consistent and reliable pneumatic support.
