Features

Industry-leading compact size

Compact size and high rigidity due to case with internal gear.
The right angle shaft PK1 type uses a spiral bevel gear on the input side, and it shortens dimension in the output shaft direction.

It based on our survey comparison.

High accuracy and high rigidity

As high precision angular contract baring with large diameter is adopted for supporting the output shaft, these products can support large radial load with compact casing.

Compatible with various servo motors

Motor adapters are compatible with major motors produced by servo motor manufacturers.

Simple motor mounting

After direct coupling the servo motor and reducer with a bolt (prepared by customer), the input shaft is fixed by tightening the built-in clamp bolt with a torque wrench, so it can be used immediately.
