Clutch Specifications


	Torque Rating		The maximum torque rating of a clutch drive.
	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 rotary power of the load that devices must handle.
	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.

	Rotational Speed		The rotary speed of the load. This specification applies only to rotary clutches.
	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.

	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.
	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 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.

	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.
	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 Operation:
	Your choices are...
	Spring Actuation / Engage		The spring engages during operation and requires power to disengage. Spring-actuated brakes are also called power-off brakes, fail-safe brakes, and safety brakes.
	Spring Return / Disengage		The brakes need power to engage. A spring is used to disengage the brake. Spring-return brakes are also called power-on brakes and non-fail-safe brakes.
	Other		Other unlisted brake operation technologies.
	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.

Features & Options



	Your choices are...
	Adjustable Torque		Adjustable torque is used primarily for slip clutches and torque limiters. Users can adjust the torque at which the clutch disengages or slips.
	Zero Backlash		There is no play or backlash during the engagement of the load and no load disengagement during a direction reversal.
	Washdown Capable		The housing is rated for washdown cleaning.
	Bi-directional		Devices can be set-up to rotate in either direction.
	Automatic Re-engagement		The clutch re-engages the load when the torque drops to an acceptable level.
	Slip Indication		Slip indication can move a pin radially when an overload occurs, or send an electrical signal to the drive motor.
	Feedback		Feedback provides an electrical or electronic signal for monitoring parameters such as position, speed, torque, lockup, or slip status.
	Other		Other unlisted, specialized, or proprietary features.
	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.

	Right Angle		The clutch or brake axis is perpendicular to the axis of the load.
	Other		Other unlisted shaft alignments.
	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.

	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.
