PosidyneTorque Ratings from 500 LB-IN to 79,000 LB-IN – up to 1500 HP

The foot mounted Posidyne Clutch Brake featuring Oil Shear Technology is oldest the most flexible clutch brake in the line. Beginning in 1969, thousands of Posidyne clutch brakes have been producing products around the world. Applications ranging from mining, lumber and steel to food processing, packaging and meat packing.

The Posidyne Clutch Brake is available in C-Face (smaller sizes), Long Coupled C face (C Face with coupling), Foot Mounted, and Piggy Back (mount the motor on top). The Posidyne comes as a clutch brake combination or clutch only. There are various operating logics which are the combination of a spring set brake or clutch or pressure set brake or clutch.

Cooling options include basic (radiant), fan cooled, water cooled, oil to air external cooling and forced lube cooling. Other options include manifold mounted valves, optical encoders, and many custom shaft styles (splined, metric, double keyway, etc.).

All Posidyne Clutch Brakes feature our world renowned Oil Shear Technology to eliminate regular maintenance, reduce cost, and increase production.

POSIDYNE CLUTCH BRAKE OPTIONS

Posidyne Clutch/Brake with C-Face

Standard NEMA C Face is available on input, output, or both in Models 02, 2.5 and 03 with input for NEMA motor frames 143T to 256T. C Face mounting to the motor and gearbox provides a compact package and ease of installation. See the long coupled C Face for higher cycle applications.

Posidyne Clutch/Brake with C-Face Long Coupled Input

Long Coupled C Face is available in Models 02, 2.5 and 03 with input for NEMA motor frame 143T to 256T. The long Coupled system uses a coupling, eliminating quill and keyway damage in high cycle, high load applications.

Piggyback Posidyne

The Piggyback arrangement allows mounting the drive motor on top of the clutch brake where length is a problem. The package includes adjustable motor base, pulleys, guard, and motor (if desired). Piggyback is available for sizes 02 through 20.

Posidyne Clutch Brake with Integral Gearbox

In some cases the off the shelf gearboxes will not provide the load capability or reliability required for a high cycle, high load application. Force Control will design and build an integral gearbox as part of the clutch brake to handle the application and provide the long life expected.

Fan Cooled Units

Fan cooled Posidyne clutch/brake units may be required for those applications where higher cycle rates are requirements. The fan blows air across the housing increasing the thermal heat dissipation capability 3 to 5 times.

Posidyne Fan Cooled Input
Water Cooled Units

Water cooling is available for those extremely high cycle, or high inertia load applications. An internal tubing coil is installed around the input shaft in the input housing. Water flowing through the tubing cools the internal transmission fluid during circulation.

Posidyne Water Cooling Coil
Oil-To-Air External Cooling

Transmission fluid is drawn out of the unit, circulated through an external oil-to-air heat exchanger (oil-to-water is available), through a filter and back into the unit. This system provides the ultimate life for the clutch brake in addition to handling extremely high thermal loads.

Expernal Cooling System
Forced Lube Cooling

Transmission fluid is pumped through the center of the output shaft, drawn out of the unit, circulated through an oil-to-water heat exchanger (oil-to-air is available), through a filter and back into the unit. This Forced Lube Cooling Unit system provides the ultimate heat dissipation continuous slip applications.

Posidyne Clutch/Brakes with Manifold Mounted Valve

The manifold mounted valve mounts directly on a machined surface on the Clutch Brake. This improves response time and positioning accuracy significantly by eliminating long hoses from the valve to the unit. It also reduces installation time and provides a cleaner package.

Washdown Duty for Food Processing Applications

All Posidyne Clutch brakes can be modified for washdown duty (USDA H-2) often found in food processing applications. Steel-It epoxy coatings on the housing, stainless steel fittings, nickel plated shafts, non corrosive breathers and sight gauge and bio-degradable fluid is included.

Marine Duty Modifications

All Posidyne Clutch brakes can be modified as marine duty. Modifications include Steel It epoxy coatings on the housing, stainless steel fittings, nickel plated shafts, and non corrosive breathers and sight gauge. Bio-degradable fluid is also included.

Posidyne Clutch/Brakes with Optical Encoder

An Optical Encoder can be furnished for improved positioning, when used with one of the CLPC Series Closed Loop Positioning Controls. The Encoder mounts on the output shaft, and includes a home position for single revolution applications.
