The Quad Plus True Constant Tension brush arm package with constant force spring assemblies delivers. It’s been tried, tested and perfected for over two years.
Quad Plus brush holders are made with the finest quality brass, solid extruded, with constant force spring assemblies. The Quad Plus brush arm package is designed specifically for your application and engineered with exclusive features that reduce maintenance costs, improve performance and extend brush and commutator life.
Heavy-duty integrated spring design with roller bearing provides more constant tension control throughout the life of the brush. That means you can install your brush and seat your brush. Less risk of commutator damage. Less chance springs will pop out or bind in the brush box. No older spring mechanism to bind up over time. Basic maintenance schedule and daily pre-run motor inspections still apply.
Prior to installation of the Quad Plus brush arm package, we require that commutator run-out be checked and adjusted to ensure true surface.
