The 36 mm Planetary Gearbox line offers firstclass, highly efficient and flexible gearboxes for demanding servo applications requiring precision and durability. Constructed from powder metallurgy or alloy steel, these small planetary gearboxes generate torque up to 7.5 N·m and are low noise (<50 dB) and have low backlash (≤2.5°). Perfect for robotics, medical equipment, and industrial automation, these direct drive timing belts can be mounted directly to DC brush type motors, NEMA 17 steppers or servo motors to maximize design efficiency.
Features
Expanded torque range: Up to 7.5 N·m (3-stage gearbox) to handle high peak loads in AGVs or robot joints.
Precision Engineering : Radial play ≤ 0.06mm, Backlash ≤ 2.5° for repeatable positioning.
Efficiency: 65–81% depending on the reduction stages to minimize energy waste.
IP65 Protection: Dust tight and protected against water jets for industrial / mobile use.
Wide Power Ranges: Wide drive ranges from 3.7:1 to 1,549:1, allow for speed-torque matching.
<50 dB Operation: Efficient design of spiral/straight teeth, and balanced gears.
