Elastomers In Compression
We gives 4 styles of 
elastomer types to allow for added flexibility in addressing particular application demands. One particular piece patterns are used in the “L” and “AL” models (referred to as spiders) and multiple part “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces based upon coupling size.
Reliable Center Spider
The sound center design is commonly used style and design when shafts in the driver and driven equipment might be kept separate by a regular gap
Open Center Spider
The open center style and design permits for the shafts of the driver and driven to become positioned inside a short distance
Open center spiders offer shaft positioning versatility but possess a lower RPM capability
Cushions
Made use of exclusively for that C and H Type couplings
Load cushions are held in area radially by a steel collar and that is attached to among the hubs
Snap Wrap Flexible Spider
Design permits for simple elimination of the spider with no moving the hubs
Lets for shut shaft separation the many way as much as the hubs maximum bore
Highest RPM is one,750 RPM together with the retaining ring, but if made use of with all the LC Form (with collar) the regular RPM rating on the coupling applies
Type is obtainable in NBR and Urethane only, and in restricted sizes
Spider Supplies
SOX (NBR) Rubber
The normal material which is very flexible material that’s oil resistant
Resembles pure rubber in resilience and elasticity, and operates effectively in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.5 occasions higher torque capacity than NBR
Fantastic resistance to oil and chemicals
Materials supplies less dampening effect and operates at a temperature variety of -30° to 160° F
Hytrel
Flexible elastomer created for large torque and substantial temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for minimal speed (max 250 RPM) applications requiring substantial torque capabilities
Not impacted by water, oil, filth, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
