BRUSH BS88A Brush

BRUSH BS88A Brush is a replacement brush used in legacy BRUSH servo motor assemblies. This spare component sits in the motor’s brush holder to maintain electrical contact with the commutator as the rotor turns, supporting proper current transfer and commutation in older servo systems. The BS88A designation aligns with the BS88 brush family and is referenced in spare-parts documentation for BRUSH Bulletin 1388 DC servo motors, making it a common wear item in maintenance or rebuild workflows. Typical applications include replacement during routine service on 1388-series servo motors and related drive configurations that utilize BS88-compatible brush assemblies. In practice, technicians select the BS88A brush to restore performance in legacy control setups where the BS88A brush matches the brush-holder design described in the motor or controller documentation. By keeping a fresh BS88A brush on hand, facilities can minimize downtime and extend the service life of existing servo installations that rely on this component.
