3502026 Dust Rubber Brake Caliper Shaft

This specialized Dust Rubber serves as a critical protective element for the brake caliper shaft within the air disc brake system. Designed to maintain the integrity of the mechanical movement, it prevents contaminants from entering the sensitive caliper components, ensuring consistent braking performance and longevity of the assembly.

3502026 is the OE-equivalent dust rubber used in the KNORR-BREMSE SM7, SN6, SN7, SK7, SL7, and ST7 braking systems. This part is engineered to meet the rigorous requirements of heavy commercial vehicle braking architectures and is compatible with MERCEDES BENZ service requirements for these specific KNORR-BREMSE hardware configurations.

For workshop technicians performing maintenance or repairs, this component is essential for ensuring the smooth operation of the brake caliper shaft. Given its Ø 69 mm diameter specification, precise fitment is vital during assembly to prevent debris ingress. Regular inspection of these rubber elements during brake service intervals helps maintain optimal system responsiveness and prevents premature wear of the caliper shaft.

This product is manufactured using heavy-duty grade materials to withstand extreme thermal and environmental stresses common in heavy-duty transport applications. It provides a reliable seal that preserves the mechanical tolerances of the braking system under constant operation.
