Description

Overview

Full-range carbon brush holders covering every current-collection application — from small box-type holders for DC motors and power tools to heavy traction, generator and high-current (500 A / 1000 A) brush holders. Manufactured in brass, copper alloy and bronze for conductivity, corrosion resistance and durability.

Range Covered

Box-type brush holders — DC motors, power tools, small machines (12.5×25 to 25×40 mm market-common)
Spring-loaded holders — constant-pressure coil/torsion springs
Terminal-type holders — insulated terminal connections (starter motors, power tools)
Multi-pocket holders — 2/3/5 brush positions for high-current commutator duty
High-current holders — 500 A / 1000 A, bronze + stainless steel, 25 mm travel
Rocker / collector brush gear — wind, power plants, generators, YZR crane motors

Why Correct Selection Matters

Brush box must match the brush cross-section exactly — oversize causes rocking/arcing, undersize causes sticking
Spring pressure must be correct — too low arcs, too high wears
Insulated mounting must isolate the holder from the frame
Brush-to-commutator contact ≥ 3/4 of the face

Before Ordering

Specify machine make/model and brush dimensions
Confirm brush box size, spring type/force and mounting pattern per SKU
High-current / multi-pocket / rocker types: supply a drawing or OEM part number for exact matching
