Description: principle in use. The hysteresis clutch With this type of clutch, one half of the clutch is coated with a hysteresis lining instead of permanent magnets. This hysteresis material works similar to the permanent magnets, but through the hysteresis lining, poles can be
- Bore Diameter: 0.6299 to 0.9449 inch
- Clutch Engagement: Noncontact
- Diameter: 2.87 to 4.13 inch
- Drive / Load Connection: In-line Shafts
