Description

Overview

The inner bush brass 38mm camshaft supports the brake cam inside its hanger bracket on heavy trailer axles. It helps keep the camshaft running true as the S-cam rotates, so braking remains smooth and predictable. As a result, fleets can maintain consistent performance with a compact service part.

Features

This inner bush uses brass to provide a durable bearing surface around the 38mm camshaft. The material handles repeated load cycles while resisting galling and fretting under normal brake service. The 38mm length also provides a practical support area to help control camshaft movement in the bracket.

• Brass construction for stable, low-friction cam support
• 38mm internal diameter to suit common camshaft sizes
• 48mm outside diameter to match typical brake bracket bores
• Suitable for heavy trailer and semi-trailer brake applications

Specifications and Materials

This inner bush suits a 38mm camshaft and uses a 48mm outside diameter to locate firmly in the hanger or support bracket. The 38mm overall length provides a compact footprint while still helping control side movement under braking load. Brass material offers reliable bearing characteristics when installed with correct lubrication. Part number: FB3152.

Compliance and Safety

Install this inner bush using standard workshop practices and follow the brake manufacturer’s service instructions. Secure the camshaft, springs and levers before removing existing bushes, then check the camshaft journal for wear and replace any damaged components at the same time. After installation, confirm free cam rotation and verify brake adjustment before returning the trailer to service.

Trailer Applications

Workshops use the inner bush brass 38mm camshaft layout on S-cam brake systems fitted to many highway and local haul trailers. It suits service jobs where the original cam support bush has worn and allowed unwanted cam movement or noise. It can also help restore positive brake feel after major suspension or axle work, and fleets often keep several bushes on hand to reduce downtime during planned maintenance.
