Description

Overview

Brake shoe knurled roller standard works as a stepped roller in heavy vehicle drum brake shoes that rely on a standard knurled roller and retainer arrangement. It helps the brake shoe follow the S-cam consistently so braking force transfers smoothly into the drum. Workshops can also replace this style of roller during routine relines, which can reduce downtime.

Features

• Stepped roller profile suits standard knurled brake shoe roller seats on common Q style heavy trailer brakes
• 58mm overall length with 19mm and 32mm outside diameters to match typical standard hardware geometry
• Knurled surface grips the brake shoe web and helps prevent unwanted roller movement in service
• Drop-in replacement that works with existing roller retainers when the brake shoe and anchor layout matches the original design

The roller length is 58mm and the stepped outside diameters are 19mm and 32mm, which align with common heavy trailer drum brake hardware. Solid steel construction handles repeated S-cam contact in demanding linehaul and local conditions.

Compliance and Safety

Brake shoe hardware affects how reliably the foundation brake operates, so follow the axle or suspension manufacturer instructions during installation. Confirm that the roller length, diameters and knurl pattern match the removed component before final assembly. After fitting brake shoe knurled roller standard, adjust the brakes according to the slack adjuster and axle maintenance procedures, then verify correct operation with a brake test.

Trailer Applications

Workshops use brake shoe knurled roller standard on heavy trailers and semi trailers that run S-cam drum brakes with standard knurled rollers. It suits general freight, tipper, tanker and other on highway equipment where standard Q type foundation brakes operate. The stepped roller also suits brake shoes and spiders designed for a 58mm roller length and matching 19mm and 32mm roller seats.
