Standard Differential Reducer PSR series
A differential speed reducer featuring high rigidity and extreme flatness made possible through thin cross roller bearings and a pin-and-hole type drive.
Its sleek, polished design contributes to the shortening and compactness of a variety of equipment.

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.
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.
