Description

Overview

The Rockwell TN trailer axle brake camshaft bush supports the camshaft in heavy trailer drum brake assemblies. It keeps rotation smooth so the brake shoes move in a controlled and repeatable way. The bush suits Rockwell TN style trailer axles and gives fleets a straightforward service part for foundation brake work.

Features

This trailer axle brake camshaft bush gives the camshaft a consistent running surface in Rockwell TN brake assemblies, which reduces play and noise in the foundation brakes. Additionally, the 38mm length, 38mm internal diameter and 48mm outer diameter match common Rockwell TN trailer configurations, so fitment is simple when you confirm the dimensions first. Furthermore, the compact design makes it easy to hold in stock for both workshop and roadside repairs. In addition, the bush supports repeated braking cycles on loaded trailers, which helps maintain predictable braking behaviour over time.

Specifications and Materials

Part number: FB2208.
Nominal length is 38mm. Internal diameter is 38mm and outer diameter is 48mm, so the bush lines up with typical Rockwell TN trailer axle brake camshaft hardware when you check the old parts before installation. The bush suits heavy trailer brake foundations where correct camshaft support keeps shoe actuation stable and consistent under load.

Compatibility and Fitment

This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 1225X804, E-2551
Before you fit the Rockwell TN trailer axle brake camshaft bush, confirm the existing bush length, camshaft diameter and housing bore against the 38mm internal diameter, 48mm outer diameter and 38mm length. Additionally, inspect the camshaft journal and bush housing for steps or scoring so the new bush seats firmly and runs true. Finally, check both sides of the axle so bush wear and brake response stay balanced across the foundation brakes.

Compliance and Safety

Technicians should isolate the trailer, chock the wheels and release air pressure before they start any foundation brake work. They then remove the camshaft and old bush, clean the housing and press the Rockwell TN trailer axle brake camshaft bush in square so it supports the shaft without binding. After reassembly, they should confirm free camshaft rotation, set the brake adjustment to the axle or OEM guideline and road test the vehicle in a controlled area. Regular inspections of bushes, cams, rollers and shoes help fleets keep braking performance within heavy vehicle road requirements.

Trailer Applications

This Rockwell TN trailer axle brake camshaft bush suits TN style trailer axles that run full-size drum brakes and 38mm camshafts. You will most often see it on heavy semi-trailers, dollies and other commercial trailers that work in freight, tipper and general haulage roles. Additionally, workshops can fit this bush during routine brake relines, full axle overhauls or targeted camshaft repairs to tidy up excess play. Fleets that carry a small stock of bushes on site can reduce downtime and keep trailers in service with quicker brake rebuilds.
