SAR Elastomeric Couplings

Replace-in-Place Technology

Power Gear Technology is proud to serve as the official Canadian distributor for Pergamon Dynamics SAR Elastomeric Couplings, featuring replace-in-place elastomeric elements that eliminate the need for time-consuming realignments. SAR couplings keep production lines running more profitably with quick and easy installations, reducing downtime and inventory carrying costs relative to other jaw or spider couplings.

With a tough polyurethane element that offers excellent wear and chemical resistance, 9 sizes ranging in torque capacity from 60 – 15,000 Nm, and ATEX certification for explosive environments, SAR couplings provide non-lubricated solutions for many challenging applications including compressors, pumps, blowers, gear boxes, conveyors, mixers, cranes, extruders, and generators.
