BEIER® Variator / BEIER CYCLO® Variable Speed Gearmotor

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.
3 Types
3 types available, each with different gear ratios and output torques.
Long Life
Extremely low friction / High durability.
Mechanical Speed Control
Mechanical speed control that is easy to operate.

Product Features

High Load Capacity
The unique friction transmission mechanism consists of multiple thin friction discs which allows for a higher load capacity thanks to the multiple pressure contact points, which result in lower surface pressure.
Withstands Overloads
The contact points transmit power in a state similar to fluid friction. Even under some overload conditions, metal-to-metal contact is prevented, as the oil film will not break.
Long Life
The friction discs are manufactured with wear resistant special alloy steel with high fatigue strength. The design is such that the oil film is always maintained on the contact surface, leading to very little wear on the friction discs, resulting in excellent durability.
