Lightweight Differential Reducer PSL series
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
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.
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 contact ratio and load dispersion have realized extremely high rigidity.
High transmission accuracy made possible through multiple meshing of high-accuracy rollers and high-precision trochoidal gears.
High-precision positioning with a backlash under 3 arcmins achieved by optimizing each component’s clearance.
Appropriate pressure angle settings for smooth operation and high efficiency.
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.
