High-Torque 45mm Planetary Gearbox | TJX45RT | Reinforced for Heavy Loads

Features

1. 45mm planetary gearbox, RT suffix for reinforced high-torque version

2. Output torque up to 16Nm continuous, peak torque 22 Nm

3. Four-stage planetary design or oversized third stage for extreme torque density

4. Output shaft diameter 16mm with double taper roller bearings

Description

TJX45RT is a high-torque variant of the 45mm planetary gearbox series. The RT (Reinforced Torque) version features an upgraded internal structure including larger module gears, a thicker output flange, and heavy-duty bearings. Output torque reaches 16 Nm continuous and 22 Nm peak. Reduction ratios from 10:1 to 500:1 are available. Backlash is kept below 1° despite the high torque capacity. Gears are carburized and ground from 20CrMnTi steel (HRC 60–62). The output shaft is 16mm in diameter, supported by double taper roller bearings for high radial and axial load capacity. The housing is made of high-strength aluminum alloy with integral cooling ribs. We provide optional motors including 45mm brushless DC motors, AC servo motors, and stepper motors with encoder feedback.

Wide range of TJX45RT configurations:

Diameter 45mm, reduction ratio 10–500:1, output torque 8–16 Nm (peak 22 Nm), backlash <1°, output shaft 16mm with keyway, IP54–IP65 protection optional.
