Oldham coupling CPG

for shaftsfor servo motorsfor encoders

Product overview
The Oldham coupling CPG is a cross-slider coupling designed for servomotors. It compensates shaft misalignment between motor and encoder to maintain precise encoder-based positioning and smooth torque transmission.

• Absorbs parallel misalignment: 0.1 mm
• Absorbs angular misalignment: 0.1°
• Axial misalignment tolerance: 0.3 mm
• Backlash-free, smooth torque transmission
• Thermal isolation from motor
• Max speed: 3000 min^-1
• Operating temperature: 0–110 °C (model dependent)
• Easy to install
