Hilliard MT Overrunning Clutches combine high torque, high speed capabilities, easy field repair and low cost – all in a compact size. With most overrunning clutches, shaft size is a major consideration. Hilliard’s new roller ramp design allows for greater shaft sizes than comparable size clutches offered by other clutch manufacturers. The assembly features the cam surface precision machined within the housing instead of the inner member, giving it the ability to reach much higher overrunning speeds and to attain greater torque in a much smaller space.
Typical applications include general backstopping and overrunning, such as suspended conveyors, indexing or ratcheting, and gear boxes.
Features:
• Flexible packaging as a clutch or clutch coupling
• Increased torque
• Compact design
• Increased shaft sizes in same physical-size units
• Custom mechanisms available
• Failure in overrunning mode; does not lock up
Clutches are available in various models from 82 to 43,600 lb.ft. at 1,000,000 cycles. Custom designs and rapid prototyping are available.

Hilliard Bi-Directional overrunning clutches replace expensive shifting and drive train assemblies. These clutches provide positive engagement automatically in either direction.
Manufactured exclusively by The Hilliard Corporation, these unique clutches feature rugged, field-proven components and are easy to service in the field. Because they can overrun in either direction, Hilliard Bi-Directional overrunning clutches are ideal for such functions as bi-directional and dual-source drives.
A specially designed unit was recently used by Polaris Industries to produce the first 4-wheel drive, all-terrain vehicle capable of providing automatic front-wheel drive engagement in both forward or reverse models.
Features:
• Senses driving direction and automatically shifts to
driving or overrunning modes
• Proven roller-ramp design
• Precision-machined components
• Bearing support and alignment of cam to drive shaft as required
Benefits:
• Reliable, durable and long lasting
• Positive engagement

Intermittent Drive Unit (IDU)
The Hilliard Corporation’s IDUs are packaged mechanical assemblies that produce precise intermittent motion – on demand – from a constantly rotating input.
IDUs feature a self-contained lubrication system, making them ideal for dusty, dirty, steamed or washed-down applications. The heart of these units is a Hilliard single revolution clutch. They are designed to provide up to 40 million cycles, with no accumulation of error in the stopping position.
When combined with an acceleration-deceleration unit (ADU), our IDUs provide smooth acceleration and deceleration through 360º - on demand.
Intermittent Drive Assembly (IDA)
Hilliard’s new IDA provides automatic control of intermittent motion from a constantly rotating power source.
This easy-to-install, self-contained package includes a solenoid-operated, single revolution clutch with anti-rollback and anti-overrun features. The rugged and proven, round-roller/cam-flat, single revolution clutch provides positive engagement at any point of revolution of the driving sleeve without slip, lag, or cumulative error.
Designed to replace and to provide greater life than wrap-spring assemblies, the Hilliard IDA is built to last through millions of cycles.

Magna Torque (MT) for Backstopping and Indexing
Hilliard’s line of overrunning clutches is economically priced and ideally suited for backstopping and gearbox applications. Custom designs and rapid prototyping are available.
Roller Ramp (MTR) for Clutch Couplings, Dual-Drive & Turning Gear
There is almost no wear during freewheeling operations in the Hilliard roller-ramp designed clutch because rollers are free to rotate between the outer member and the inner cam. Typical applications for this clutch are blowers, pumps, fans, conveyors and forming rolls.
Enclosed Overrunning Clutches
Hilliard’s enclosed overrunning clutch incorporates superior MTR design in a totally enclosed package. Designed for power transmission operations, this clutch is totally contained in a stationary housing for constant protection from hostile environments or washouts.
High-Speed Overrunning Clutches
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. Typical applications include hydraulic, electric, and pneumatic turbine starters; turbine drives, and turbine auxiliary drives.

Ortlinghaus multiplate safety clutches are permanently engaged, this condition being maintained by spring pressure. They are able to transmit torque up to a particular, preset level, after which in the case of an overload in the transmission, they are designed, to slip for a limited period of time. They can thus be used to safeguard all types of transmission lines in machines and equipment from overloading and destruction. They have the task of smoothing out high torque peaks, at start ups, and during the operating of a line. This is done by the clutch plates slipping past each other for a short period of time when the desired maximum torque is reached.
The torque at which a clutch starts to slip can be varied, within limits. In this way these clutches safeguard gear wheels, shafts and other drive elements from damage and thus guarantee operational reliability for an extended period of time; in this way they also help to prevent the need for repairs. It must be kept in mind that when the clutch is slipping, frictional heat is produced and released within the set of plates and that the permissible amount of heat is limited. This thermal loading must be kept within the required limit with the aid of a slip monitoring device, which would switch off the drive. This is necessary with fast running drives where the critical amount of heat is reached very rapidly when slipping commences.

Like the Hysteresis Brake, the Magtrol Hysteresis Clutch develops torque strictly through a magnetic air-gap, ensuring an absolutely smooth transmission of torque from the drive unit to the driven element. Designed to be powered without the use of brushes or slip rings, and being a pure hysteresis device, there is never any fear of contamination due to wear particles or leaky seals. This makes Magtrol Hysteresis Clutches and Brakes ideal for use in food processing and clean room environments.

The Safegard series of overload clutches from Cross+Morse were developed to provide overload protection of high torque values with a compact unit. Directly interchangeable with other units in the market, this series offers low cost precision with minimal maintenance for a long reliable service life.
Safegard clutches are in two basic series, the Standard series, for optimum speed and torque, and the Mini series, for lower cost option on slower speed drives. Both series are also available as shaft couplings.
Four options of operation are available.
1. The basic Safegard CSF design, using ball driving system for high speed, non synchronous applications.
2. The Synchron CSY design, with roller drive for lower speed synchronous applications.
3. The Safe Lift CSL, also with roller drive, but remaining in constant drive, only indicating overload by axial movement onto the limit switch.
4. The Safebreak CSZ design where the unit is held on totally free running condition after overload and requires manual re-engaging

These brakes are widely used in Winch and Mining Applications, and are designed for dynamic breaking with oil in the disc-pack chamber, and can also be used dry as holding brakes.
They are engaged by disc-springs and disengaged by a pressure supply to the cylinder which moves the piston axially, compressing the disc springs and releasing the plates. The hub is usually fitted to the end of the shaft whuch is being braked.
56P Features
* Spring-applied, ensuring automatic braking in the event of a power failure
* With all working parts being enclosed, the brake is suitable for external mounting, even in unfavourible environments
