Description

Overview

SAF Holland outer bush 1.5in is designed for heavy trailer camshafts, giving stable support where the cam passes through the brake bracket. This SAF Holland outer bush 1.5in helps maintain correct camshaft alignment, which keeps foundation brakes operating smoothly and reduces uneven wear. As a result, it suits workshops that want reliable, OEM-style service parts for SAF camshaft assemblies.

Features

This bronze outer bush supports the camshaft journal while allowing consistent, low-friction rotation during brake application. The 38mm inner diameter matches 1.5in camshafts, so the bush locates accurately on common SAF brake hardware. The 45mm length and 42mm outer diameter provide a useful bearing surface without taking up unnecessary space in the hanger or bracket. Bronze construction also helps resist seizure compared with many softer bush materials.

You can replace the SAF Holland outer bush 1.5in during a camshaft overhaul without disturbing the full axle assembly. This suits preventative maintenance programs where cam tubes, S-cams and bushes are serviced together to help reduce downtime and unexpected brake issues.

Specifications and Materials

Part number: FB3018.

This SAF Holland outer bush uses a bronze alloy body that balances strength, wear resistance and machinability for trailer brake hardware. Key dimensions supplied are length 45mm, inner diameter 38mm and outer diameter 42mm, which together suit standard 1.5in camshafts in SAF applications. In addition, the solid bronze sleeve style spreads contact loads evenly along the camshaft journal.

Compatibility and Fitment

This outer bush suits 1.5in SAF camshafts where the hanger or bracket is machined for a 42mm outside diameter bush and 45mm length. Therefore, it is typically used in SAF camshaft brake systems on heavy trailers that run European style axles and foundation brakes. 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. 1230010604, BP7133

Compliance and Safety

Correct bush fitment helps the camshaft rotate cleanly so brake shoes apply and release as intended. When bushes wear, excess camshaft movement can reduce brake performance and accelerate lining wear, so timely replacement supports safer operation. Always follow workshop procedures and torque any related hardware to the axle or brake manufacturer’s specifications. In addition, confirm brake adjustment and complete function checks after refitting the camshaft and bush.

Trailer Applications

This SAF Holland outer bush 1.5in is intended for heavy transport trailers running SAF axles with cam-operated drum brakes. Typical use cases include semi-trailers, B-double sets and similar combinations that operate on highways and regional routes. It suits both fleet maintenance and independent workshops that regularly service European style trailer axles. For example, it can be fitted during full brake relines, camshaft replacements or hanger refurbishments.
