Description

Overview

The inner bush Ingersol 39mm supports the S cam in Ingersol style trailer foundation brakes and helps keep the camshaft running true in service. As a result, it helps maintain consistent brake shoe contact and more predictable stopping performance on heavy trailers.

Features

• Inner bush Ingersol 39mm suits trailer brake camshafts in Ingersol style foundation brakes.
• 19mm length with 39mm ID and 48mm OD for compact yet stable camshaft support.
• Simple press fit replacement that matches typical trailer workshop tools and methods.
• Cost effective way to control camshaft movement before it creates uneven brake wear.

Specifications and Materials

This inner bush Ingersol 39mm suits camshaft housings built around a 39mm shaft diameter, with 48mm outer diameter and 19mm overall length, so it aligns with common Ingersol style trailer brake layouts. Material is a robust bushing grade suitable for repeated brake cycles in heavy vehicle service.

Part number: FB2216.

Compatibility and Fitment

This inner bush Ingersol 39mm suits camshaft housings that match the 39mm internal diameter and 48mm outer diameter stated above. 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. E-536, 405122

Compliance and Safety

Correct camshaft bushing condition is critical for balanced foundation brake operation, because excessive cam movement can cause uneven shoe contact and longer stopping distances. Additionally, technicians should inspect the bush whenever drums or linings change and replace it if they see any noticeable play or scoring on the cam. Finally, after installation, check that the S cam rotates freely without binding and confirm that all brake hardware follows manufacturer procedures.

Trailer Applications

Workshops typically use the inner bush Ingersol 39mm on trailers running Ingersol pattern axles in local freight, linehaul and general semi trailer work. Consequently, it suits fleet operators who maintain mixed age equipment and prefer to replace individual camshaft components instead of complete axle assemblies. In addition, workshops often use this bush in repairs where only the worn inner bush needs replacement to bring camshaft support back within acceptable limits and extend the service life of other brake hardware.
