Description

Overview

The camshaft support bracket Rockwell ARN ATN TN RL type acts as a hanger for the brake camshaft bush on compatible heavy trailer axles. It supports the camshaft around a 38mm inner diameter bush, so the S-cam stays aligned through each brake application. It also helps transfer braking loads into the suspension hanger and chassis, which supports smoother foundation brake operation over time.

Features

This camshaft support bracket suits Rockwell ARN, ATN, TN and RL-style cam layouts on Freighter RN and Paymaster trailers. The four-hole mounting pattern helps workshops secure the bracket to matching hangers with a straightforward fit. It also uses a 38mm bush bore to suit standard outer bush and camshaft combinations, which can simplify stock control. When a bracket is worn or damaged, technicians can replace it without special fixtures or complex alignment tools.

Specifications and Materials

Part number: FB3005.
This camshaft support bracket uses a 38mm bush inner diameter and a four-hole mounting pattern. It matches typical Rockwell ARN, ATN, TN and RL hanger brackets on trailer axles. It also suits common S-cam brake hardware where the camshaft runs through a bush and support bracket mounted to the suspension hanger.

Compliance and Safety

Supporting the brake camshaft correctly is critical for reliable heavy vehicle braking, so technicians should install the camshaft support bracket Rockwell ARN ATN TN RL type in line with axle and brake manufacturer procedures. When replacing the bracket, inspect the camshaft, bushes, seals and mounting hardware for wear or damage. Always chock wheels, support the trailer on rated stands, and isolate air supplies before working on any S-cam or foundation brake components.

Trailer Applications

Workshops typically use the camshaft support bracket on semi-trailers and other heavy trailers running Rockwell ARN, ATN, TN or RL running gear on Freighter RN and Paymaster fleets. It suits general freight, tanker, bulk and curtain-sider applications where S-cam brakes rely on a hanger-mounted bracket and bush to carry the camshaft. If your fleet shares similar hangers and cam layouts across multiple trailers, this general purpose design can help standardise parts.

Cross-reference and Suitability

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

Always confirm the bush size, hanger details and camshaft specification against existing hardware before ordering. Then fit the camshaft bracket once you have checked the match.
