Reinformed Ball Reducer SFP series

<span>Reinformed Ball Reducer <br>SFP series</span>

A Ball Reducer featuring increased allowable torque due to its improved cycloid curve in the torque transmission section, its allowable radial load has also been enhanced by using three-point support for its output shaft bearing.

Technical Information

Highlights

  • Improved Load Capacity

    Boasts improved allowable radial load of the output shaft and enhanced rigidity, with every component upgraded based on the BR Series.

  • Zero-Backlash

    Uses a steel ball in the deceleration mechanism instead of a gear. Eliminates backlash and enables prevision feeding and high-precision positioning through constant rolling contact via preload.

  • Compact & Simple

    Has a reduction mechanism and input/output bearings built into its housing for compactness and ease of installation.

  • Motor Attachment Standardization

    The SFP Series has standardized motor attachments for servo motors of various manufacturers, allowing the motor to be immediately installed after purchase.

  • Maintenance-free

    Its grease-filled reducer can be used without lubrication for its entire rated life. Also has no mounting position restrictions.

  • High Efficiency

    Its transmission mechanism uses a large number of steel balls to achieve a high-efficiency drive. The rolling contact of the balls is similar to that of a ball screw, allowing extremely light operation and maximized capacity of any motor.
