Help with Flexible Couplings specifications:

Coupling Type
   Coupling Type:       
   Your choices are...         
   Coil Spring       Coiled springs are used to couple shafts. This coupling type is used in instrument and low horsepower applications. 
   Double Loop Coupling       Double loop couplings consist of a solid elastomeric element with two U-shaped webs that connect the shaft attachment hubs. This coupling type permits a relatively high degree of axial misalignment. 
   Elastomeric "Tire" Shape       Shaft hubs are attached to either side of an elastomeric "tire". This coupling type accommodates angular and parallel misalignment as well as end-float. 
   Flexible Link       Three cantilevered beams or links are arranged in a triangle and attached to hubs and torque sleeves. Flexible links handle angular, parallel, and axial misalignment. 
   Gear / Multi-Jaw       Gears with external teeth are mounted on shafts. A sleeve with internal teeth fits over the gears. This widely used coupling style provides high torque and allows axial misalignment, but usually needs lubrication and good shaft alignment. 
   Helical / Slit       Helical or slit couplings prevent backlash and provide constant velocity with angular misalignment. They are designed for high speeds and do not require lubrication.  Helical and slit couplings are flexible beams machined from a solid piece of material with a bore through the center.  Slit couplings have several slits, machined on the periphery of the coupling that allows the beam to flex.  A helical coupling is a type of a slit coupling and has a continuous, helical slot in the center section, machined through to the bore.  Both coupling types have no backlash and constant velocity with angular misalignment. They can operate at high speeds with no lubrication. 
   Magnetic       Permanent magnets are mounted on shafts separated by a nonmagnetic barrier. Magnetic coupling provide torque ratings to 500 ft.-lb. and can eliminate the need for seals. 
   Metal Bellows       Metal bellows couplings are designed for high speeds and light-duty applications. They prevent backlash and do not provide cyclic speed variation. 
   Metal Contoured Diaphragm       Torque is transferred through contoured, metallic diaphragms. This coupling type provides high horsepower and revolutions per minute (RPM). 
   Roller / Silent Chain       Sprockets on each shaft are coupled by a chain or chains. This coupling style is suitable for heavy-duty, high torque applications. 
   Schmidt Coupling       Torque is transmitted through a series of plates connected by links. Schmidt couplings permit large lateral misalignment. 
   Shear Coupling       Shear couplings contain metal inserts for shaft attachment inside an elastomeric coupling that will shear or tear in over-torque or machine jam conditions to prevent motor or machine damage. 
   Sliding Block / Oldham       Slotted or jawed flanges on shafts transmit torque through a captured sliding disk or block. 
   Steel Grid       Slotted flanges on each shaft are coupled by a flexible steel band that is laced through the slots. This coupling type provides good shock absorption. 
   Spider Coupling       Spider couplings use an elastomeric ring with multiple radial arms in between a rigid component on each side: drive, and driven. The elastic component allows for some axial and radial misalignment. Spider couplings can assist in absorbing shock loads due to high acceleration, deceleration, or change of direction. 
   Torsionally Flexible Coupling       Torsionally flexible couplings incorporate an elastomer member and have the ability to dampen vibration, absorb shock, and twist without causing damage. Torsion forces are applied when one end of the device moves in one direction, while the other end either remains fixed or moves in the opposite direction. 
   Wafer / Flexible Disc       Torque is applied through sheet-metal plates mounted to shafts and intermediate plates by two-point supports. This coupling type is suitable for light- to moderate-duty applications. 
   Other       Other unlisted, specialized, or proprietary coupling types.
