Right-Angle 38mm Planetary Gearbox | TJX38RO | 90° Output with High Torque

Features

1. 38mm right-angle planetary gearbox, RO suffix

2. Output torque up to 55 Nm, reduction ratios 10–200:1

3. Spiral bevel input stage for smooth and quiet operation

4. Compact right-angle housing with multiple mounting faces

Description

TJX38RO is a right-angle 38mm planetary gearbox using spiral bevel gears for the input stage. Output torque reaches 55 Nm. Reduction ratios from 10:1 to 200:1. Backlash <1.5°. The spiral bevel design provides smoother meshing and lower noise than straight bevel gears. The housing has mounting holes on both input and output faces for flexible installation.
