Industrial gear units

ZOLLERN industrial gears are planetary gears designed for continuous use. They have been proven under extreme application conditions and in special applications.

The industrial gears are based on a modular system. They are available with a motor, coupling and brake. Different output and drive variants are available. Combinations with bevel gears and spur gears are possible.
