Description

Overview

This camshaft seal 1.5in cam helps protect heavy trailer foundation brakes by keeping grease around the camshaft and limiting dust, water and road grime. It suits 1.5in brake camshafts where a compact seal sits close to the cam head in a tight hardware stack. As a result, it supports consistent brake performance across busy highway and local fleets.

Features

This camshaft seal 1.5in cam uses a 38mm inner diameter that locates firmly on the camshaft journal to help control lubricant at the seal land. The 48mm outer diameter suits common housing bores on trailer brake spiders, while the 5mm thickness keeps the seal profile shallow so it fits neatly with existing washers and bushes. The general purpose design also allows workshops to standardise on one seal for many 1.5in camshaft applications.

Specifications and Materials

This camshaft seal 1.5in cam suits a 1.5in brake camshaft with a nominal 38mm inner diameter, 48mm outer diameter and 5mm thickness, consistent with the dimensions shown in the original reference listing. Workshops can use it in greased camshaft housings on heavy trailers where regular cleaning and inspection of the seal land are part of the service routine. Part number: FB3122.

Compliance and Safety

Heavy vehicle brakes depend on clean components, so check the camshaft bushes, seal land and housing bore before fitting this camshaft seal 1.5in cam. Remove old grease, rust and wear ridges, then confirm the camshaft rotates freely without excessive side play. In addition, follow trailer or axle manufacturer procedures and lockout rules when working on air brake systems.

Trailer Applications

You can use this camshaft seal 1.5in cam on heavy trailers that run 1.5in brake camshafts, including many highway semi trailers, tankers and general freight combinations. It suits brake overhauls where seals show leakage or contamination, and it also fits fleet maintenance programs that replace camshaft seals as part of scheduled foundation brake servicing. As a result, workshops can keep a small quantity on hand to cover multiple trailer models.
