READ MOREThe 8FPM4L brake caliper is a core component of the heavy machinery braking system. The brake caliper adopts a composite drive mechanism of spring activation and pneumatic release. The spring module provides basic braking force through preload, while compressed air (working pressure range 4-8 bar) is used to quickly release the brake, with a response time of only 0.3 seconds. Its dual-piston symmetrical layout and enhanced hydraulic cylinder with a diameter of 45mm can output a braking torque of up to 4500N·m, suitable for 200-355mm brake discs, and suitable for heavy-duty scenarios such as port cranes and mining transport vehicles.
In terms of product material technology, the piston surface of the 8FPM4L adopts silicon nitride gradient coating technology, and a 3μm thick ceramic layer is formed by chemical vapor deposition, with a hardness of 1600HV and a high temperature resistance threshold of over 750℃. The frame is made of high-strength alloy steel cast by low-pressure sand mold, and the internal porosity is controlled within 0.3%. The brake caliper supports modular customization. Users can choose the thruster installation direction (left/right side) and manual wear compensation mechanism, and achieve friction plate gap calibration with an accuracy of 0.1mm by rotating the adjusting bolt.
