Fine Cyclo® High Precision Gearboxes

Low noise and simple basic type

DA Series

  • Easy mounting

    Supporting high-speed shafts with a bearing makes it easy to mount.

  • Compact in shaft direction

    The overall length can be reduced because the motor shaft can be inserted into the gearbox.

  • Gearboxes with adapters for servo motors are also available

    Gearboxes with adapters for the main motors (shafts with or without keys) of each servo motor manufacturer can also be manufactured.

E Cyclo® High Precision Gearboxes

Compact high precision gearbox integrated with a strain wave gearing mechanism and the tooth profile of the CYCLO gearbox

ECY Series

  • Compact and high torque

    Equipment can be downsized because the allowable peak torque is about 1.5 times (typical value) that of common strain wave gearing (equivalent size).

  • High rigidity

    Increasing the strength of equipment and reducing vibration is possible because the spring constant is about double (typical value) of the common strain wave gearing (equivalent size).

  • Simple mounting large hollow high-speed shaft

    The oil seal structure, filled with lubrication grease and high-speed shaft bearing support makes it easy to mount. The large hole diameter of the high-speed shaft allows cables and shafts to pass through.

  • Prevents ratcheting

    Since ratcheting does not occur so easily, this is a very safe gearbox against overloads.
