Electric Clutch/Brakes for Face-Mount Motors
From one assembly, electrically control when to transmit power with a clutch and when to hold a load in place with a brake. The clutch and brake each have their own circuit, so they can be controlled separately. To disengage either one, remove power to its circuit. Disengaging the clutch disconnects the load from your motor, stopping power transmission without stopping your motor. Disengaging the brake releases it.
These clutch/brakes have a mounting pattern that is designed to mount directly to your NEMA face-mount motor. Fasten them to your motor's shaft by tightening the set screws, which bite into your shaft for a tight hold. To the other side, attach a gearbox or couple a gear, sprocket, pulley, or other component.
Controllers (sold separately) convert an AC input into two DC outputs that alternate engaging the clutch and the brake. If their green LED is lit, the clutch has power. If their red LED is lit, the brake has power. Mount these controllers inside a conduit box (sold separately).
Conduit boxes (sold separately) attach directly to these clutch/brakes to protect wiring from dust and moisture.
Covers (sold separately) change the open design of these clutch/brakes into a totally enclosed fan-cooled unit, protecting them from dust and moisture.

Precision Overload-Protection Spring-Loaded Torque Limiters
With zero backlash (no play), there’s no motion lost when these torque limiters transfer torque, so machines move smoothly with accurate and repeatable motion. They protect your machinery if there is a jam, emergency stop, or other overload by cutting off torque when a maximum torque is reached. They automatically resume transmitting torque once it drops below the set maximum. When they resume, they start transmitting torque from the same position where they stopped, keeping your drive and output sides in sync. They should not be used in applications that frequently exceed the set torque. You can adjust the set torque by using a spanner wrench to twist the adjustment ring.
To help you detect an overload, they have a sensor ring that moves out of place when these limiters cut off torque. Use a sensor (not included) to trigger an alarm or a shutdown when the ring moves.
They clamp evenly around your shaft for more holding power than set screws and won't damage your shaft.
Shaft-to-shaft torque limiters also act as a flexible shaft coupling, so they compensate for angular and parallel misalignment as they regulate torque transmission between shafts. This reduces vibration and protects components from wear. For a complete unit, you’ll need a torque limiter, a hub, and a spider (all sold separately).
Through-shaft torque limiters regulate torque transmission between an input shaft and a mounted component, such as a pulley, sprocket, or gear.

One-Way Clutches
Since they transfer torque in one direction and spin freely in the other, these clutches are useful in applications where you don’t want motion to reverse, such as in backstopping, indexing, and overrunning. For example, they can be used to prevent a conveyor from reversing direction. They’re through-shaft clutches, so they regulate torque transmission between a drive shaft and a mounted component such as a pulley, sprocket, or gear.
When choosing a clutch, consider how much torque you need to transfer. Roller clutches are best for low- to medium-torque transfer in overrunning and indexing applications. Sprag clutches handle higher torque than roller clutches because they have more contact points. This makes them best for backstopping applications.
You should also consider how the clutch will attach to your mounted component. Clutches with a knurled hub can be press fit into the bore of your component. Clutches with a keyed hub let you slip on your component. Clutches without a hub have a precision ground outer race, so they can be press fit directly into a component and positioned anywhere along the length of your shaft. They also have mounting holes on their face you can use to secure your component or an anti-rotation device, such as a torque arm, for a different backstopping setup.
Clutches that mount to shafts with set screws bite into your shaft when tightened to hold it. Clutches that mount to shafts with a slip fit must be secured with a shaft collar or in some other way that prevents them from moving along the length of your shaft.
Covers protect you from rotating equipment when the clutch is mounted to the end of the shaft.
Torque arms work as an anchor for clutches in backstopping applications. Mount to the outer race of your clutch and a stationary piece of equipment.

Soft-Start Centrifugal Clutches
Disengaged until they rotate fast enough to transmit torque, these clutches give the components on your driven side a smooth start by allowing the driving side to start without load. Fasten them to your shaft by tightening the set screws, which bite into the shaft to hold it.
Shaft-to-shaft clutches also act as a shaft coupling, allowing you to regulate torque transmission between two shafts.
Through-shaft clutches regulate torque transmission between an input shaft and a mounted component.
Clutches with support rollers are quieter and last longer than other centrifugal clutches because the contact points are supported by urethane rollers to prevent slipping.
Clutches with a pulley come ready to install a V-belt.
Spring kits allow you to change the speed at which the clutch engages.

Electric Clutches for Face-Mount Motors
Designed to mount directly to a NEMA face-mount motor, these clutches let you electrically control when to transmit power without turning off your motor. When you remove power to these clutches, they stop power transmission by disconnecting your motor's load. Fasten them to your motor's shaft using the set screws, which bite into the shaft for a tight hold. To the other side, attach a gearbox or couple a gear, sprocket, pulley, or other component.
Controllers (sold separately) convert an AC input into a DC output to engage and disengage these clutches. They mount inside a conduit box (sold separately).
Conduit boxes (sold separately) attach directly to these clutches to protect wiring from dust and moisture.
Covers (sold separately) change the open design of these clutches into a totally enclosed fan-cooled unit, protecting them from dust and moisture.

Speed Reducers for Roller Conveyors
Also known as pallet brakes, these reducers mount on a gravity conveyor and create friction on the rollers to control the conveyor's speed. Speed reducers have an internal brake that gradually engages as the speed of the rollers increases. For best results, the spacing of the reducers should be equal to the length of the material you're conveying.
Inline-mount rollers are often used for floor-mounted conveyors or those without much clearance underneath because they are mounted at the same level as other rollers on the conveyor. They come into direct contact with the load.
Under-mount reducers prevent damage to the load because they don’t come into direct contact with it. Instead, they are mounted underneath the conveyor where they contact the conveyor rollers.

Rotary Speed Limiters
Install these rotary speed limiters at the hinges of small lids, doors, and access panels for smooth, quiet motion. They're often used in electronics applications.
Speed limiters with a 360° rotation angle are often used to move small hoods, flaps, and fans. A cycle is one shaft rotation.
Dual direction speed limiters dampen motion in both directions. Common uses for them include controlling the motion of a switch-activated door and opening and closing a DVD player.
Clockwise and counterclockwise speed limiters dampen motion in the listed direction, moving freely in the opposite direction. Use them in processes that require returning a part to its original position.
