Multiple Disc Mechanical Clutches (MMS/MMD)

Carlyle Johnson's Mechanical Multiple Disc mechanical clutches provide 3 to 6 times the torque produced by a single disc mechanical / friction clutch of the same package size, making them the ideal solution for high torque, limited space requirements.

Separator springs are used between each pair of inner discs on these mechanical clutches, providing the advantage of truly floating discs. This ensures that there is negligible drag, no abrasion, and consequently no heat generated when the clutch is in neutral. A locking plate on the disc end of each unit (two on double types) locks all discs against compression by the lever system.

As with all Carlyle Johnson products, our multiple disc mechanical clutches can be customized to meet your applications. Our engineering department can also custom-design and produce a mechanical or friction clutch to fit your exact requirements.

Features of MMS/MMS Multiple Disc Clutch Units

The MMS/MMD unit's clutch disc features a bronze or steel friction clutch surface for added life, superior consistency for indexing and for excellent torque transmission. Shipped fully-assembled CJM multiple disc mechanical clutches arrive ready to be slipped onto a shaft.

When needed, manual adjustment to the clutch is made by temporarily loosening the lock screw on the split type adjusting ring, then turning the ring to give the desired shifting pressure. Only a hex key wrench is required for this adjustment.
