Description

Overview

This SAF bush spherical component supports the camshaft in the brake spider so the shaft can rotate smoothly while staying correctly aligned under load. It suits SAF axle brake assemblies and helps maintain consistent brake response on heavy trailer suspension systems.

Features

This SAF bush spherical profile allows the camshaft to self-align slightly as the suspension and brake components move under service conditions. Additionally, the compact 38mm internal diameter and 59mm outside diameter suit common SAF axle brake spiders. The simple cylindrical form also makes inspection, cleaning and replacement straightforward during routine workshop maintenance.

Specifications and Materials

Part number: FB2248.
The bush length is 55mm, with a 38mm internal diameter and 59mm outside diameter to match typical SAF camshaft and spider bores. The spherical outside surface helps share load evenly across the spider housing as the camshaft rotates.

Compliance and Safety

Correct camshaft bush support is important for safe, even brake operation, so this SAF bush spherical design should be inspected whenever brake linings or camshafts are changed. Additionally, you should check for excessive play, flat spots or visible scoring on both the bush and camshaft before reassembly. Always chock wheels, isolate the trailer and release air pressure safely before working on foundation brakes, and follow your workshop’s lockout procedures as well as relevant heavy vehicle maintenance guidelines.

Trailer Applications

Workshops typically use this SAF bush spherical unit in the camshaft support position on SAF trailer axles where the bush must support rotation and minor misalignment. In addition, it suits fleet operators who want consistent brake feel across multiple trailers that run SAF axles. When replacing worn bushes, technicians should also inspect spiders, slack adjusters and camshafts so the new bush can run on serviceable mating parts.

Cross-reference and Suitability

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

When selecting a SAF bush spherical replacement, always match the bush length, internal diameter and outside diameter to the original component on the axle to avoid excessive play or tight spots during operation.
