25 23 12 Crankshaft Flange for Air Brake Compressors

What does a crankshaft flange do?

This compressor crankshaft flange serves as a critical component within the air brake compressor assembly, ensuring stable rotation and structural integrity of the crankshaft. Manufactured from heavy-duty grade materials, it is designed to withstand the high-pressure cycles and mechanical stresses typical of pneumatic braking systems in heavy commercial vehicles.

Compatible vehicles and engines

This component is widely used in various heavy-duty applications, including trucks and buses from makers such as KamAZ, Dongfeng, Zhongtong, Yutong, Liaz, Iveco Bus, Paz, Ford Trucks, Volkswagen, Nefaz, and their respective models. It is specifically engineered to work with Cummins engines including the ISBe, ISLe, and ISDe series. The part is also compatible with Knorr-Bremse systems.

Installation and maintenance

When performing maintenance or repair on the air brake compressor, technicians should inspect the flange for any signs of wear or misalignment. Ensuring a secure fitment during installation helps maintain the airtight integrity of the compressor assembly and prevents premature failure of the piston or connecting rod components. Check the compatibility list to ensure correct application.

Selection guidance

Proper selection of this flange ensures that the compressor operates within its intended pneumatic parameters. For heavy commercial vehicle fleet managers and workshop technicians, using high-strength components is essential for minimizing downtime and maintaining braking system reliability.
