Extra-High Torque 32mm Planetary Gearbox | TJX32RX | 35 Nm Continuous

Features

1. 32mm planetary gearbox, RX suffix for extreme torque

2. Output torque up to 35 Nm continuous, peak 55 Nm

3. Carburized and ground gears (HRC 60–62)

4. Heavy-duty tapered roller bearings on output

Description

TJX32RX is the highest torque 32mm planetary gearbox available, delivering 35 Nm continuous and 55 Nm peak torque. The RX version uses carburized and ground gears (HRC 60–62), a reinforced planet carrier, and tapered roller bearings on the output shaft. Reduction ratios from 5:1 to 200:1. Backlash <0.8°. Ideal for applications where a larger gearbox cannot fit.

Wide range:

Diameter 32mm, torque 25–35 Nm (peak 55 Nm), ratios 5–200:1, backlash <0.8°.

Applications

- Electric motorcycle throttle actuators

- Heavy industrial grippers

- Construction equipment controls

- High-force linear actuators

Advantages

1. Extreme torque: 35 Nm continuous in 32mm form factor.
2. Ultra-hard gears: HRC 60–62 for wear resistance.
3. Precision backlash: <0.8° for positioning.
