Lightweight Differential Reducer PSL series

<span>Lightweight Differential Reducer <br>PSL series</span>

The lightest differential speed reducer compared to other same-sized precision speed reducers that use aluminum as the main component.

This reducer is useful for robots, AGVs, and other equipment requiring lightweight and thin profiles.

Technical Information

Highlights

  • Ultra-flat and compact design

    The adoption of a differential reduction mechanism and a thin cross-roller bearing has enabled an ultra-flat form. This contributes to the realization of contraction and compactification of equipment.

  • Lightweight

    New lightweight model that uses aluminum for its main components, reducing its weight by about 30% compared to its predecessor. Example: PSR70FCA: 0.62kg → PSL70FCA: 0.42kg

  • High rigidity

    High contact ratio and load dispersion have realized extremely high rigidity.

  • High Accuracy

    High transmission accuracy made possible through multiple meshing of high-accuracy rollers and high-precision trochoidal gears.

  • Small backlash

    High-precision positioning with a backlash under 3 arcmins achieved by optimizing each component’s clearance.

  • High Efficiency

    Appropriate pressure angle settings for smooth operation and high efficiency.

  • Maintenance-free

    Grease-filled and maintenance-free. No need to refuel and no restrictions on mounting position.

  • Motor Attachment Standardization

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