Description

Overview

Flanged inner bush 38mm gives a robust bearing surface for heavy vehicle brake camshafts. It supports the cam as it turns through the brake cycle, so the shoes apply evenly. The flanged shoulder helps locate the bush in the spider and control thrust loads. As a result, this compact bush plays an important role in keeping foundation brakes smooth and predictable.

Features

• 38mm internal diameter to suit common heavy trailer brake camshafts
• 37mm bush length for stable support inside typical brake spiders
• 48mm outside diameter to match standard bores in many foundation brake housings
• Flanged design to manage axial location and reduce side movement of the camshaft

Specifications and Materials

This flanged inner bush 38mm uses a steel construction to handle the radial loads and shock seen in air brake camshaft service. The 38mm internal diameter, 48mm external diameter and 37mm length match the common dimensions used in many trailer and truck brake spiders. Technicians can pair this bush with suitable grease to maintain a stable film between the camshaft and bush under repeated brake applications. Part number: FB2223.

Compliance and Safety

Brake hardware carries high loads, so it is important to inspect the camshaft, spider bore and bracket before you press in a new flanged inner bush 38mm. You should replace badly pitted or undersize camshafts instead of relying on the bush alone. Additionally, always press the bush squarely into the housing and avoid using a hammer that could distort the flange or bore. In addition, reassemble the brake with clean components and correct torque on all fasteners so the system continues to comply with workshop and roadworthiness guidelines.

Trailer Applications

Workshops use this flanged inner bush 38mm in a range of heavy trailers and dollies that run cam-operated drum brakes. It suits fleet maintenance where you need to restore correct cam support without changing complete spider assemblies. Furthermore, it is a practical option for on-vehicle repairs when the housing is still within tolerance but the original bush has worn or seized. In many cases, replacing bushes as a set on both ends of the cam helps maintain even brake performance side to side.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

You should always confirm the 38mm internal diameter, 48mm outside diameter and 37mm length against the removed bush and brake spider before final fitment.
