Constant Pressure Spring Assemblies

SEW offers replacement spring assemblies or spring repair for virtually every type of constant force brush holder, including turbine ring magazines. Our spring assemblies are designed to meet or exceed the performance of the original part. Over 25 popular spring styles are carried in stock.

SEW Quick Disconnect (HQDs) terminals and mounts make changing carbon brushes fast and easy. With no screws to remove or replace, the HQD terminals and mounts snap together in a tight positive locking action. The electrical connection remains secure in the roughest of conditions and styles and sizes can be threaded to fit most existing equipment. The HQDs are manufactured to handle 200 amps continuously.

Shaft Grounding Brush Holder:
Check out our shaft grounding brush holder and brush holder kit, which effectively shunts static and induced shaft currents away from the bearing. The silver graphite brush maintains the lowest contact drop so shaft voltages stay at safe, minimum levels near zero in an effort to provide you with fast, easy brush changes.
