Planetary gear reducers are compact components that strive to maximize the transmission of torque in various applications. The mechanisms ensure the transmission of high torque levels while simultaneously decreasing the required number of motor revolutions for a set level of power.

Planetgear concentric inline gear reducers offer reliable operation through self-aligning planet carriers that float radially and axially to provide perfect alignment of the drive train. State-of-the-art materials and processes provide hardened, wear-resistant gearing that handles heavy-duty applications and shock loads.

Rax Motor’s Planetary Gear Reducer stands out for its high precision, low backlash, and exceptional shock load capacities. With ratios ranging from 3:1 to 100:1 and frame sizes from 42mm to 180mm, it offers versatile mounting options.

Compact, High Torque Planetary Gear Reducer. 27° pressure angle results in increased gear dedendum strength, as well as the ability to withstand heavy shock loads. Compact, torque dense design. Modular design allows the unit to be compatible with different configurations using only a minimum number of parts.

Planetary gearboxes refer to a gear system in which, in addition to rotating around their own axis like fixed axis gears, their axis of rotation also rotates around the axis of other gears along with the planetary carrier.

Our inline planetary gearbox configurations provide the highest efficiency and best output torque of all our speed reducers. These gearboxes are designed to handle varying loads with little backlash. Planetary gear reducers operate more quietly than parallel shaft reducers.

Ondrives.US’ tapered planetary gear reducers are inline gearboxes that deliver low backlash performance at operating speeds as high as 3,000 RPM. Both models feature slim, compact designs, making them ideal for applications where space is limited.

Plan-Star’s Revolution Series consist of a complete range of multi-purpose planetary gears, which can be operated by electric and hydraulic motors. The revolutionary style provides features others just can’t offer!

This standard range of Precision Planetary Reducers are perfect for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo motor technology, providing tight integration of …

The purpose of a planetary gear reducer is to multiply the torque of an electric motor while proportionally reducing the speed with maximum efficiency. Planetary gear reducer design consists of an input sun gear that turns several orbiting planet gears within an outer ring gear (image, below).
