| Spring Assistance: | |||
| Your choices are... | |||
| Spring Actuation / Engage | The device is spring-actuated and needs power to engage. | ||
| Spring Return / Disengage | The spring provides return force and the device needs power to disengage. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Clutch Engagement | |||
| Your choices are... | |||
| Noncontact | Devices use a noncontact technology such as a magnetic field or eddy currents to provide engagement and drive. | ||
| Friction | Friction between contact surfaces transmits power. This is the most common configuration. | ||
| Toothed | Toothed contact surfaces transmit power without slipping. No heat is generated. Devices are engaged only when stopped or running at a slow speed (< 20 rpm). | ||
| Wrap Spring | Torque is transmitted from input to output by a coiled spring that wraps around the output element. The device is disengaged when the spring is uncoiled via a control tang at its end. | ||
| Oil Shear | Drive engagement is achieved by the viscous shear of transmission fluid between the device's plates. | ||
| Plate / Disc | The torque level is controlled by compression springs which force plates together. | ||
| Ball Detent | Ball detent is a slip mechanism in which, upon overload, balls ride up out of seats to overcome springs or air pressure engagement. | ||
| Roller Detent | Rollers, held in place by springs, wedge between the inner and outer races to engage the clutch. | ||
| Pawl Detent | Pawl detent is a slip clutch mechanism in which, upon overload, the pawl overcomes spring or air pressure engagement and rotates out of its detent. | ||
| Sprag | Sprags are steel wedges that tip in one direction to wedge between inner and outer races. They can be configured with either the inner or outer race as the input or output. Too much torque makes the sprags tip so much that contact is not maintained. Often, sprag clutches can transmit more torque than other designs of slip or overrunning clutches. | ||
| Other | Other unlisted, specialized, or proprietary clutch engagement mechanisms. | ||

Brake Specifications

|
|
| ||
| Torque Rating | The maximum torque rating for the brake should equal or exceed the application's requirement. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Power | The maximum power rating for the brake. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Speed | The maximum rotary speed rating. This specification applies only to rotary brakes. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Maximum Pressure | The maximum pressure for a hydraulic brake. | ||

| |||
| Brake Engagement: | |||
| Your choices are... | |||
| Noncontact | Braking action is achieved through a non-contact technology such as a magnetic field, eddy currents, etc. | ||
| Friction | Friction between contact surfaces transmits power. This is the most common type of brake. | ||
| Toothed | Toothed contact surfaces transmit power without slipping or heat generation. Teeth are engaged only when stopped or running at a slow speed (< 20 rpm). | ||
| Wrap Spring | A coiled spring wraps downward onto the rotating element. The brake is disengaged when the spring is uncoiled via a control tang at its end. | ||
| Oil Shear | Braking action is engaged via the viscous action of the shearing of transmission fluid. | ||
| Other | Other unlisted, specialized, or proprietary brake engagement mechanisms. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Brake Type: | |||
| Your choices are... | |||
| Band | Band brakes are the simplest type of brake. They have a metal band lined with heat- and wear-resistant friction material. | ||
| Drum | Drum brakes press shoes against a spinning surface. They are often used on automobile rear wheels. | ||
| Disc | Disc brakes have brake pads, a caliper, and a rotor. During operation, the brake pads are squeezed against the rotor. Disc brakes have good heat dissipation properties. | ||
| Cone | Cone brakes consist of a cup and a cone which is lined with a heat- and wear-resistant friction material. During actuation the cone is pressed against the mating cup surface. Cone brakes are not commonly used. | ||
| Other | Other unlisted, specialized, or proprietary brake engagement configurations. | ||

|
| ||
| Shaft Configuration: | |||
| Your choices are... | |||
| In-line | The clutch or brake shaft is along same axis as the driven or braked load. | ||
| Parallel | The clutch or brake shaft is parallel, but offset from the axis of the driven or braked load. | ||
| Right Angle | The clutch or brake axis is perpendicular to the axis of the load. | ||
| Other | Other unlisted shaft alignments. | ||

| |||
| Drive / Load Connection | |||
| Your choices are... | |||
| In-line Shafts | The drive and the load have shafts which attach to a through-bore. | ||
| Through Shaft | The drive shaft attaches to a bore and the load is driven through the outer diameter. | ||
| Shaft - Pulley / Gear / Sprocket | The drive shaft attaches to a bore and the output is a drive component such as a pulley, gear, or sprocket. These clutches are often designed to accept different drive components. | ||
| Flange | The brake or clutch is mounted to the object in motion via a flange. | ||
| Other | Other unlisted direct shaft attachments or flange mountings. | ||
