Description

Overview

The Camshaft Seal Rockwell 1 5/8 Inch helps control grease and contamination around Rockwell brake camshafts on heavy trailers. It supports the camshaft as it passes through the brake spider and helps protect the inner bushes and brackets. Because of this, the seal helps maintain consistent brake response and can help reduce premature wear in the foundation brake assembly.

Compliance and Safety

Correct camshaft sealing supports brake compliance because it helps maintain predictable shoe return and lining clearance. A sound seal also reduces the risk of grease migrating onto brake linings, which can severely reduce friction. Technicians should inspect the camshaft, bush and spider surfaces for damage or scoring before installing a new seal. After reassembly, they should function-test the park and service brakes to confirm even application and release across the axle set.

Trailer Applications

This Camshaft Seal Rockwell 1 5/8 Inch suits Rockwell 1 5/8 inch brake camshafts used on semi-trailers and dollies. It fits brake spiders and cam tubes that match the 41mm by 51mm seal envelope. Fleet managers can use the same Camshaft Seal Rockwell 1 5/8 Inch across compatible axles to simplify inventory and help reduce unplanned downtime.
