Posidyne 1.5

The Posidyne Clutch/Brake standard for performance and durability is available for your smaller 1/2 to 5 HP drives for conveyors, packaging machines, food processing applications and extruder cut-offs.

The size 1.5 Posidyne boosts the cycle rate (up to 300 CPM), accuracy, and life (20,000,000 – 40,000,000 cycles). They bring oil shear durability to a new level of performance and convenience in a compact, lightweight (aluminum housing), double C-Face mounted package.

The new split clamped quill input eliminates key and key-way problems associated with competitive clutch/brakes. The minimal inertia of cyclic parts, combined with high torque handling capability, puts more usable horsepower into your drive – quicker. The 1.5 Posidyne can cycle up to 300 times per minute, and with oil shear technology can last for years, making them perfect for those high cycle applications. High heat dissipation capability ensures long life and consistent accuracy in 24 hour operations. Convenient options such as foot mounting kits, manifold mounted valves and optical encoders are available to fit most any application.

Typical Applications


C-Face Mounting

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.

Fan Cooling

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.

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.

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.

Washdown Duty for Food Processing

The Posidyne 1.5 Clutch brake can be modified for washdown duty (USDA H-2) often found in food processing applications. Steel-It epoxy coatings or nickel plated housing, stainless steel fittings, nickel plated shafts, non corrosive breathers and sight gauge and bio-degradable fluid is included.

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.

Foot Mounting Kit

The Posidyne 1.5 is designed to be double C-Face mounted. However, a foot mounting kit is made available for certain applications. Foot kits are made of heavy gauge steel and are used to reduce overhung load.

Integral Gearbox for High Cycle Rates

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.
