Freewheel Clutch

Line up

Cam & Roller Type (Radial load resistance)

• With bearing function (radial load resistance)
  → Contributes to downsizing and weight reduction of the unit
• Cams share the load evenly
  → Transmits assist force with high precision
• Concentric retainer structure
  → Reduced frictional torque in idle rotation contributes to quieter operation and improved ride quality

Camcage Type

• Superior torque transmission performance (based on our comparison test)
  → Contributes to downsizing and weight reduction of the drive unit
• Cams share the load evenly
  → Transmits assist force with high precision

Built-in Bearing Type

• All-in-one (inner/outer ring, cam, bearing)
  → Contributes to downsizing/weight reduction of units
• Cams share the load evenly
  → Transmits assist force with high precision
• Concentric retainer structure
  → Reduced frictional torque in idle rotation contributes to quieter operation and improved ride quality

Cam & Roller Type (Axial and radial load resistance) Under development

• Bearing function included (axial and radial load resistance)
  → Can be used with helical gears, contributing to further downsizing and weight reduction of the unit
• Cams share the load evenly
  → Transmits assist force with high precision.
• Concentric retainer structure
  → Reduced frictional torque in idle rotation contributes to quieter operation and improved ride quality
