Clutches

Torque Limiter delivers zero backlash operation.

Mechanical Torque Limiter isolates driving from driven elements within milliseconds. While offering precise overload protection, rotary motion control product is torsionally rigid and provides double bearing support of pulley/sprocket. Product is factory-set to lowest torque within range and can be adjusted without being removed from application. Areas of use include machine tools, automation...

Clutch/Brake Modules require no maintenance.

Clutch/Brake Modules require no maintenance.

Electromagnetic Smooth-Start UniModules provide consistent, smooth starting and stopping throughout entire torque range. Units are NEMA C-face compatible and automatically adjust for wear. They can be paired with CBC-300 clutch/brake control, which allows clutch and brake torque levels to be set independently. Once torque levels are set, control's circuitry supplies constant current to...

Fluid Coupling produces soft start/stop for belt conveyors.

Fluid Coupling produces soft start/stop for belt conveyors.

True Torque(TM) incorporates brake disc into fluid coupling mounting arrangement and features adjustable metering orifices. When starting inclined belt conveyor, product provides soft start, eliminating belt liftoff and stretch. During shutdown, application of brake decelerates conveyor belt and prevents conveyor rollback. Coupling, constructed with double delay chamber, can achieve 40 sec...

Cushioned Clutch enables higher machine speeds.

Cushioned Clutch enables higher machine speeds.

In addition to overload protection, an increase in machine speed can be obtained by inserting slip clutch into system. Friction surfaces result in static friction being less than dynamic friction, which cushions suddenly applied loads. Tension on paper, wire film, and thread is gradually applied and is half of suddenly applied load. Machine itself will also be cushioned from shock, elongating...

Torque Limiters protect machine and drive systems.

Torque Limiters protect machine and drive systems.

Integrated with Steelbelt Speed Reducers, adjustable Torque Limiters are mechanical, using slip clutch assembly in oil bath. Clutch slips automatically to minimize downtime, and allows reducers to return to normal operation after obstruction is removed. Limiters are adjustable from 0 lb-in. up to 25% above full torque rating. They are suited for conveyors, gate operators, overhead doors, bottling...

Clutch offers torque rating of 75 lb-in.

Long Life Clutch employs wrap-spring technology that produces consistent and repeatable engagement timing. While clutch engagement time is proportional to relative speed, once spring has wrapped down, clutch output is brought up to full speed in as little as 3 msec. Disengagement is nearly instantaneous. Clutch's rating makes it suitable for automatic door systems, pump drive systems, and any...

Clutches offer consistent timing for rotary motion control.

Clutches offer consistent timing for rotary motion control.

Models EC5, EC15, EC20, and EC30 provide up to 1 million actuations at dynamic load capacity. Electromechanical wrap spring clutches provide torque in only one direction, which permits overrunning. Once spring has wrapped down, each clutch can accelerate loads from 0 to full speed in less than 3 msec. Typical operating speeds are 100-800 rpm with 1,400 rpm max.

Ball Detent Torque Limiters disengage at preset values.

Ball Detent Torque Limiters disengage at preset values.

Bidirectional Type BD torque limiters protect rotating machines and components from damage in case of jam/overload. Adjustable overload settings cause unit to disengage mechanically when overload occurs and trip a limit switch or signaling device. BDR units have automatic random reset, while BDS units offer automatic single position reset and use rollers instead of balls. Random reset or single...

Electric Slip Clutch uses asbestos-free friction system.

Electric Slip Clutch uses asbestos-free friction system.

Electro Slip Clutch offers continuous or intermittent slip with up to 30 million cycles. Torque is gradually applied and electrically controlled, enabling change during operation. No suddenly applied load is transmitted through mechanism, reducing shock and making unit suited for design engineering applications such as tension control on wire, film thread, and paper.
