Ruiding Precision Transmission PSE Straight-Tooth Planetary Reducer

MANUFACTURER DOCUMENTATION

Overview

The PSE catalog page describes a straight-tooth planetary reducer, separate from Ruiding’s AF helical design. The official model code lists PSE042, PSE060, PSE090, PSE120 and PSE160 frames with one-stage ratios of 3 to 10 and two-stage combinations up to 100. The performance table is frame-specific: PSE060 at 3:1 has 18 Nm nominal output torque, while the same frame’s nominal input speed is 3,000 rpm. One-stage efficiency is stated as at least 96 percent and operation is specified between minus 10 and plus 90 degrees Celsius. The P1 one-stage backlash row varies by frame, so do not assign one precision figure to every PSE. Check the exact input flange and output-shaft drawing.

Model configuration table

The source page provides a series overview rather than a complete model/ratio rating table. Use the manufacturer link above for selection drawings and confirm the precise operating point before ordering.

Before you specify this gearbox

A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.

Confirm continuous, peak and emergency-stop load limits separately.
Match the motor flange, shaft, mounting orientation and lubrication requirements.
Request the current drawing revision and selection calculation from the manufacturer.
