Multiple Disc Mechanical Clutches or Brakes (MMS & MMD)
- Highest torque in the smallest space
- Simplicity of design allows for wide range of adaptability
- Exclusive MAXITORQ® “Floating Disc Packs” reduce drag, abrasion and heat build-up in neutral and provide consistent release
- Positive engagement/disengagement at any speed
- All units may be run in oil or dry applications
- Easy on-line manual adjustment allows for fine-tuning of the device
- Torque range 5 lb. ft. - 2000 lb. ft.
The MAXITORQ® Mechanical Multiple Disc clutches and brakes provide 3 to 6 times the torque produced by single disc clutches and brakes of the same package size, making them the ideal solution for high torque, limited space requirements. The clutch disc feature a bronze or steel friction surface for added life, superior consistency for indexing and excellent torque transmitting characteristics. The unit is completely assembled and shipped ready to be slipped onto a shaft.
Separator springs are used between each pair of inner discs. These separator springs provide the advantage of truly floating discs, which 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 locks all discs against compression by the lever system. Manual adjustment 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 an hex key wrench is required for this adjustment.
We are able to modify our standard product, offer custom products previously designed by our own engineering staff, or custom design and develop a new product to meet your specific needs.
Multiple Disc Mechanical Overload Release Clutches (MOR & ORI)
- Dependable, positive safety protection for operators and machines – eliminates costly shutdowns
- Recommended where excessive torsional loading from heavy shock or sudden over normal load are present
- Automatically disengages – will not transmit any torque until reengaged
- Easy on-line adjustment allows for wear compensation and for release settings over a wide range of torque values
- Highest torque in the smallest space
- Easy on-line manual adjustment allows fine-tuning of the device
- Single position and multiple position clutches available to provide accurate registration
- Torque range 5 lb. ft.- 2000 lb. ft.
The MAXITORQ® Overload Release clutch is comprised of or standard mechanical multiple disc clutch with overload release features. The overload release occurs as a result of cams placed on the shifter sleeve and drive cup. When an overload occurs the discs slip, causing the cams to come into contact. The shifter or sleeve is then forced into a neutral position.
The MAXITORQ® Overload Release clutch is designed to protect a machine and its products against damage resulting from accidental overloading of the mechanism. The overload clutch comes with a ring type drive cup and hub adapters as a package, designed for a particular application. The driving ring cup connects the overload release clutch with either the driven or driving device.
Special overload release shifters are available for clutch sizes 20 – 26. Shoes and studs are available for all sizes including 27 and 28 for riveting into shifter yokes designed by the customer.
A limit switch can be incorporated into the power input line. The clutches may be used on a continuous shaft, or as a cut-off coupling type for connecting two shafts.
Multiple Disc Mechanical Torque Limiters (TL1, TL2 & TL3)
- High torque in a small size
- Sustains torque level
- Durable
- Predictable dynamic and static torque
- Easily adjustable over a wide range
- Superior adjustment retention
- Designed for easy rebuilt with no special tools required
- Torque range 5 lb. ft.- 2000 lb. ft.
MAXITORQ® torque limiters provides protection against overloads while sustaining torque so that shutdown and restart is not required. Acting like a torsion shock absorber to permit “slip” if the torque exceeds an adjustable pre-set level, these units are used in any application where obstructions can cause overloads or where production is sensitive to over tensioning.
Depending on size, the torque limiters are adjustable over a wide torque range from 1lb.ft. to 1500 lb. ft. Small space-saver sizes from 2 3/16" to 8 5/8" O.D., and high torque potential make them the best possible choice for machine tools, conveyor systems, off-highway mobile equipment or any other application where obstructions can cause temporary overloads or where over- tensioning is a problem, as in textile or paper mills. Torque limiters can be pre-set to transmit torque constantly regardless of the speed of the drive mechanism. When a jam occurs, the torque limiter will slip but the torque level is accurately sustained.
Disc Pac Modules (MDP)
- The MAXITORQ® Multiple Disc Pac will allow you to assemble clutches and brakes to your own specifications
- Simplicity of design offers high versatility
- Compact and self contained
- Available in 8 standard disc diameters
- Completely assembled
- Separator springs assure a drag-free neutral
- Standard lugs configurations vary from 3 to 12 lugs depending upon torque rating; splines are also available

The MAXITORQ® Disc Pacs can be used with air, hydraulic, electric or manually operated brakes and clutches. The Disc Pac keys to a shaft and is available in eight sizes from 2" to 8" diameter with over 100 variations. The static torque averages from 4 lb. ft. to 2000 lb. ft. All assembly, disassembly and adjustments are manual. No special tools are required. Standard ring cups and flange driving cups are available if desired. The Disc Pac can be used as a multiple disc clutch or brake, an overload release clutch or a torque-limiting device.
The design allows for easy rebuilding of worn assemblies as needed. We are able to modify our standard product, offer custom products previously designed by our own engineering staff, or custom design and develop a new product to meet your specific needs.
Accessories
Manual Shifter Yokes
The MAXITORQ® Manual Shifter Yoke Assemblies, complete with shoes and studs, with or with out base, and are available as a stock item for MAXITORQ® Mechanical Clutches and Brakes in sizes 21 – 26. Guaranteed to mate perfectly with our clutches and brakes.
Shifter Shoes and Studs
Should you choose to fabricate your own shifting mechanism, a pair of our shifter shoes be included in the design. They should be attached directly opposite each other and allowed to float
in the groove of the clutch shifting sleeve. Our shifter shoes are fabricated from a slow-wearing material which is adaptable to any speed suitable to your clutch operation.
