Description

Overview

This camshaft outer bush Hendrickson Intraax part supports the S cam journal where it passes through the brake spider on heavy trailer axles. It keeps the camshaft centred under load, so braking forces transfer cleanly into the suspension and axle. As a result, the bush helps maintain consistent brake timing and reduces wear in demanding trailer fleets.

Features

This outer bush suits Hendrickson Intraax camshafts with a 38mm shaft diameter. The 38mm length provides a stable bearing surface in the spider while still leaving space for seals, washers and circlips in the cam stack. Additionally, the 51mm outer diameter matches typical brake spider bores used on Intraax drum brake suspensions. Furthermore, the bush works with matching inner bushes and cam tube components to keep the S cam aligned through repeated brake applications.

Specifications and Materials

The outer bush has a 38mm internal diameter, a 51mm external diameter and an overall length of 38mm, which matches common Hendrickson Intraax camshaft journal dimensions. It functions as a brake spider bush for S cam journals on heavy trailers that use Intraax air suspension systems. Part number: FB3137.

Compatibility and Fitment

This outer bush suits Hendrickson Intraax camshafts where the brake spider is machined for a 38mm S cam journal and matching cam tube hardware. Always compare the existing bush dimensions and the suspension identification tag before you select replacement parts. 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. BP2217, S-22898, S22898

Compliance and Safety

Correct S cam bushing plays a direct role in safe braking performance because excessive clearance or misalignment can lead to uneven shoe wear and longer stopping distances. Therefore, inspect the S cam, bushes, seals and cam tube together and replace any worn components as a set. During service, chock wheels securely, isolate air supplies and follow workshop procedures for working around heavy springs and rotating brake hardware.

Trailer Applications

This camshaft outer bush Hendrickson Intraax component fits highway trailers, tankers and general freight equipment that run Hendrickson Intraax air suspension with drum brakes. Workshops can use it for single axle repairs or as part of scheduled fleet maintenance, where standardised camshaft hardware improves consistency. In addition, it suits rebuilds where technicians restore worn brake spiders to correct S cam support.
