3502021 SB6 SB7 SN6 SN7 SK7 Bushing Brake Caliper Pin

The precision of a braking system depends heavily on the quality of its smallest components. This brake caliper pin bushing is engineered to provide stable guidance and reduce friction within the caliper assembly. By maintaining a consistent Ø 39 mm diameter, it ensures that the caliper operates smoothly under heavy-duty conditions, preventing uneven wear and ensuring reliable braking response.

This technical component is specifically designed to be compatible with KNORR-BREMSE systems, including the SB6, SB7, SN6, SN7, and SK7 series. It is also engineered for compatibility with SCANIA and ZF braking hardware. 3502021 is the OE-equivalent bushing used in the KNORR-BREMSE SB6, SB7, SN6, SN7, and SK7 brake caliper pin systems.

For workshop technicians performing routine maintenance or brake overhauls, this bushing offers a seamless fit for heavy commercial vehicle brake systems. Regular inspection of caliper pins and bushings is essential to prevent vibrations or uneven caliper movement. This part is ideal for maintaining the integrity of air disc brake systems in trucks and buses during intensive service intervals.
