BEIER CYCLO Variator Overview
For over 80 years, Sumitomo Drive Technologies has been providing world-class gearmotors, gearboxes, and speed reducers, featuring industry-leading technology with fully integrated premium efficient motors. Our impactful power transmission units come in various shaft configurations such as right angle, concentric and inline.
Sumitomo BEIER CYCLO Variator Gearmotors are an essential tool for many drive systems. With unique designs and configurations available, gearmotors can be used to increase torque, reduce speed, reverse direction, or change the push or pull of a driveshaft.

Mechanical stepless speed control with high capacity and long life, with over 50 years of tradition and trust.
Unique friction transmission mechanism results in a higher load capacity, due to multiple pressure contact points that lead to a lower surface pressure. Extremely low wear on the friction discs, for excellent durability.
