BRUSH HOLDERS

For all types of electrical rotating machines.

The brush holders are made  from brass, gun-metal, phosphor bronze and other alloy castings as per the requirements. Sheet metal holders are also made to substitute castings where ever possible and permissible. The holders and brush cavities are machined to close tolerances and to a fine finish for smooth and trouble free travel of the brush. The spring pressure is calibrated and tested accordingly to the prescribed table for particular grade and cross sectional area of the brush and care is taken to provide centrally uniform spring pressure. All hardware is suitably plated and holders are checked at every stage of manufacture for strict quality control.
