Low-inertia, oil-shear design ends fade, early failures above 70 cycles per minute. Tough job-proven, high performance clutch/brakes deliver 600+ cpm with up to 500 brake hp

MARCH 2003 -- No matter how you slice it - speed, precision or reliability - Posidyne® oil-shear clutch/brakes beat all comers in cut-to-length performance. Engineered for 600+ cpm and up to 500 brake hp, Posidyne® clutch/brakes offer vital performance reserve for critical applications demanding high repeatability and 24/7 runtime reliability. Proven solutions for over 20 years to rapid and precise stopping, starting, reversing, speed changes and positioning, the American-made Posidyne® clutch/brakes work tough in industry's most rugged conditions and applications - wood/lumber production, foundries, steel mills, mining and mineral processing, and insulation/roofing products manufacturing. Heat dissipating oil-shear design comes on strong at higher cycle rates (above 70 cpm) and heavy loads where conventional designs can fade and fail. Proprietary stack-the-deck engineering - multiple small-diameter disks on the brake stack - optimizes friction area while reducing inertia for world-class accel/decel in fast cycling operations.

The versatile Posidyne® clutch/brakes come in 11 basic sizes, each with five control logic options, four cooling system choices, and eight different mounting configurations.

Creative design by Force Control Industries, the leader in oil-shear technology, dissipates heat, reduces friction wear, and cushions engagement shocks, while saving on energy, downtime and maintenance costs. Posidyne® clutch/brakes transmit torque by shearing automatic transmission fluid between the multiple friction discs, reducing wear contact for exceptionally long service life. The fluid absorbs the heat of engagement and dissipates it through the housing. The high thermal capacity virtually eliminates torque fade and provides excellent positioning repeatability in cycling applications.

Fluid shear cushions engagement to reduce load shocks and component stresses for long drive life with minimum of maintenance. Pneumatic actuation makes it easy to precisely control both torque and engagement speeds with an ordinary pressure regulator, as well as adjust for rapid or soft starts/stops. The design reduces high starting in-rush currents and associated power factor imbalance, saving on energy costs.
