• Automatic disengagement • Maintains high torque while engaged • Ball bearing support and alignment of cam to drive shaft • Bronze roll cage • Positive engagement • Clockwise or counterclockwise rotation available The Hilliard High-Speed Overrunning Clutch provides positive engagement and high torque on demand. Featuring a unique roller-ramp design, the clutch when engaged transmits power via the precision-machined cam and roller assembly connected to the input shaft. A ball bearing at each end of the roll cage supports and aligns the cam in relation to the drive (output) shaft. The roller-cam...

The Hilliard centrifugal clutch provides automatic, gradual, cushioned engagement over a speed range on high-inertia loads. It smoothes out and reduces starting current surge. • Slip-free at rated load and speed • Protects against overload by limiting torque • Absorbs shock, eliminates torsional resonance • Soft transmission of power • Load free starting Blower or Fan Drive Mill or Kiln Drive Uses standard squirrel cage motor with across-the-line starting. Eliminates costly reduced voltage starter. Reduces shock loading on gear teeth. Smoothes out pulsating loads and current peaks. Eliminates...

EXTREME DUTY CENTRIFUGAL CLUTCHES The patented Hilliard Extreme Duty Centrifugal Clutch has been engineered in pulley and sprocket versions, to provide long service life and is ideal for retrofit or new equipment applications. A thermodynamically designed clutch shoe increases the clutch's capacity to absorb heat without damaging the integrity of the clutch. Specifications/Size Range * Non-standard bore sizes are available in OEM quantities. Extreme duty clutch couplings also available on request.

The Hilliard Corporation has designed a CVT system that is more advanced than any other belt drive system currently available on the market. The Hilliard clutch system utilizes a tight belt which allows for seamless engine braking and belt protection at start up and during overload situations, to extend belt life. The Hilliard Continuously Variable Transmission system is designed to fit a wide variety of clutch envelopes so no expensive modifications are required for new vehicles or on replacements for vehicles currently in the field. Engine Braking The patented Hilliard CVT system incorporates...

AUTO-LOK™ The Hilliard Auto-Lok™ Differential offers equal power transferred to both wheels regardless of traction, allowing positive back drive through both wheels. • Locks and unlocks automatically • Easy operation and steering Typical applications include snowthrowers, lawnmowers, trenchers, self-propelled and walk-behind equipment. Larger Auto-Loks can be used on golf carts and utility vehicles. While the machine moves in a straight path in a two-wheeled application, both wheels have positive drive. When the machine turns left or right, the inner wheel will be the drive wheel and the outer...

• Amusement Rides • People Movers ELECTRIC BRAKESPositive stopping. Reliable holding. Designed for maximum flexibility and long, dependable service, our electric brake is electromagnetically released when voltage is applied and spring-engaged when current is interrupted. • Heavy-duty friction disc for long service life • Fully epoxy-potted coil • Easy-to-adjust wear bolt compensates for friction surface wear and extends brake life • Conservatively rated helical springs • Wall or bearing mounted • Many different voltages available Specifications/Size Range

Powerful floating caliper design can be used on conventional disc or rail applications. The compact spring-applied design provides easy installation and maintenance. Spring force and air gap can be adjusted to match torque requirements. The patented Hilliard MK Guide Rail Brake is designed for use on elevators, conveyors, cranes, or other devices requiring a spring-applied electromagnetically released brake. The patented MK brake can be applied to a guide rail or a brake disc. It is unique in that it is direct acting with only one moving part. The brake incorporates an electromagnetic coil that...
