Raymond Motor Brush Set RA570-358-461 – RA570-358/461

This carbon motor brush set is built for Raymond electric lift trucks, providing the replacement brushes that maintain electrical contact between the stationary motor housing and the rotating commutator inside a DC traction or pump motor. Carbon brushes ride against the commutator under spring pressure, transferring current as the motor spins.

The set weighs 0.2 pounds and measures roughly 2 inches by 1 inch by 2 inches per brush, dimensions consistent with a small set of carbon brush blocks rather than a full motor assembly.

Carbon brushes are a scheduled wear item by design, since the brush material is engineered to wear gradually against the commutator rather than damage it. As the brush material wears down, the spring-loaded brush holder advances to maintain contact, but once the brush wears past its usable length, contact becomes intermittent, which typically shows up as arcing, reduced motor power, sparking visible at the motor housing, or a motor that cuts out under load. Replacing the brush set before the brushes wear out protects the commutator from the pitting and scoring that occurs when a worn brush loses consistent contact pressure.
