Selection notes
- Transmittable torque values match Miki Pulley catalogue data for this model.
- Shaft diameter and transmittable torque are shown per model; contact us for additional dimensions, materials, tolerances, installation torque, speed limits and axial load ratings.
- Posi-Lok devices are shaft locking bushings, not flexible couplings.
- PSL-G and PSL-K are distinct Posi-Lok series with different construction (flangeless vs flanged).
