Force Control Industries presents their Posidyne X Class Clutch Brakes which feature Oil Shear technology that allows rapid and precise stopping, starting, reversing, speed change and positioning – all without adjustment and virtually no maintenance.

Ideal for applications with frequent start/stop cycles, these unique motion control devices allow higher cycle rates (as high as 300 cycles per minute), and unparalleled service life (20 to 40 million cycles) to increase production rates with lower downtime.

With unparalleled speed and precision, the value engineered X Class Clutch Brakes allow machine designers to run at higher cycle rates and quality levels or design new machines for higher performance at a reasonable cost. They are ideal for many OEM applications including conveyors, packaging machinery, food processing, meat packing, dynamite/gunpowder processing, production machinery, extruder cut-offs, palletizers, feeders, inserters, loaders, cut-offs, fillers, and more.

The Posidyne X Class features an innovative Split Clamped Quill feature, which reduces shaft and key/keyway damage to the motor shaft associated with competitive clutch/brakes. The split quill collar tightens the quill 360 degrees around the shaft and key for superior connection.

Convenient options such as foot mounting kits, manifold mounted valves and optical encoders with closed loop positioning controls are available to fit most applications. The totally enclosed Posidyne X Class is impervious to dust, dirt, chips, etc. With a washdown or marine duty option they are resistant to chemicals, coolants, caustic wash down, weather, and more, making them ideal for hostile environments,

The Posidyne X Class is inherently explosion proof with the addition of an explosion proof actuation valve. A standard valve could also be remotely mounted in an explosion proof cabinet.

All Posidyne clutch/brakes are designed with low inertia cycling components. This makes them even more efficient, requiring less motor horsepower to accelerate the load, and less torque to stop the load. By reducing the motors’ high inrush currents and the associated power factor imbalance, these unique clutch/brakes can provide significant energy savings in 24/7 manufacturing demands.

A simple actuation system allows torque in the clutch and brake to be precisely controlled through air or hydraulic pressure control. Adjustment for rapid or soft starts and stops is easily accomplished. Manifold mounted control valves reduce response times by eliminating hoses and fittings while providing a space efficient design.

The Posidyne X Class clutch/brake can be actuated either by air or hydraulic pressure for use in plant or outside applications. The hydraulic actuation package includes a hydraulic pump, solenoid valve, regulators, and a filter. A heat exchanger can be added for additional cooling for unusually high loads or cycle rates.

Oil Shear Technology is the reason that brakes by Force Control last up to 10 times longer than standard dry friction brakes and do not need maintenance, adjustment, or disc replacement. Unlike dry clutches and brakes, oil shear technology provides a film of transmission fluid between the brake disc and the drive plate.  As the fluid is compressed, the fluid molecules in shear transmit torque to the other side.  This torque transmission causes the two components to reach the same relative speed.  Since most of the work is done by the fluid particles in shear, wear is virtually eliminated.  Elimination of wear also eliminates the need for adjustments which are common for dry braking systems, especially spring set brakes.

In addition to transmitting torque, a patented fluid recirculation system helps to dissipate the heat from the friction surface to the housing where it is cooled. The inability of the dry friction units to dissipate the heat out of the friction material is a major cause of wear and friction material breakdown.

Along with heat removal and torque transmission, the fluid serves to continually lubricate all components of the oil shear units, significantly increasing their service life.

The Posidyne X Class clutch brake is not a servo, however it can often be used where the highest servo performance or complexity is not required, but performance beyond that of an ordinary clutch brake is. The Posidyne X Class cycles faster, stops more accurately, and provides years of trouble-free service – without the need for a servo expert on staff.
