Speed Variators

Mechanical stepless speed variators for manual speed adjustment in industrial equipment.

Product Overview

JWB-X Mechanical Speed Variator

Mechanical Stepless Adjustment

Manual mechanical speed setting through a compact variator structure.

Process Speed Fine-Tuning

Suitable for production sections where speed changes by process condition.

Compact Reducer Combination

Can combine with NMRV / RV reducers for adjustable-speed right-angle units.

Different from Electronic Inverter Control

JWB-X is mechanical; SV200 is for electronic motor speed control.
