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.
Mounting Geometry




   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.
 
   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.
 
   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.
   Bore Diameter
 
     The bore diameter.
 
   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.
   Diameter
 
     The diameter or cross-sectional width of the brake or clutch assembly.
 
   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.
   Length
 
     The dimension along the axis of rotation.
 
   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.
   Weight
 
     The weight of brake and/or clutch.
 
   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.
