Planetary gear units

Maximum power transmission with powerful, precise and versatile planetary gear units. BEGE is your engineering partner for high-torque drives.

Planetary gear units for maximum power transmission

Planetary gear units are an ingenious gear mechanism in which the driving and driven shafts are in line. This clever design makes it possible to transfer high levels of power in a limited space. The gear unit consists of a sun gear, several planetary gears, and a ring gear. This configuration distributes the torque over the three planetary gears, so the torque can be up to three times higher than with traditional gear units.

BEGE supplies STM planetary gearboxes designed to offer impressive power, strength and versatility. These robust systems are shock-resistant and can handle large radial and axial loads with ease. With high reduction ratios, an excellent weight-to-power ratio and high output torque, they are ideal for applications requiring precision and power. In addition, they offer impressive performance with minimal backlash for maximum accuracy and controlled movements, making them especially attractive for applications with low speeds and high torques.
