Elastomers In Compression
We offers four varieties of elastomer styles to allow for supplemental versatility in addressing specific application necessities. One particular piece models are used in the “L” and “AL” models (known as spiders) and numerous portion “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces dependant upon coupling size.
Solid Center Spider
The sound center design is generally utilised design and style when shafts of the driver and driven gear is usually stored separate by a normal gap
Open Center Spider
The open center design and style lets for your shafts with the driver and driven to become positioned inside 
of a short distance
Open center spiders offer you shaft positioning flexibility but have a reduce RPM capability
Cushions
Utilized solely for your C and H Variety couplings
Load cushions are held in spot radially by a steel collar that’s connected to among the hubs
Snap Wrap Flexible Spider
Layout makes it possible for for quick removal from the spider devoid of moving the hubs
Lets for near shaft separation each of the way as much as the hubs maximum bore
Greatest RPM is 1,750 RPM using the retaining ring, but if employed using the LC Kind (with collar) the regular RPM rating in the coupling applies
Type is available in NBR and Urethane only, and in limited sizes
Spider Resources
SOX (NBR) Rubber
The normal material that’s remarkably flexible materials that may be oil resistant
Resembles normal rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has one.five times higher torque capability than NBR
Excellent resistance to oil and chemical substances
Material offers significantly less dampening result and operates at a temperature range of -30° to 160° F
Hytrel
Versatile elastomer designed for large torque and high temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for lower pace (max 250 RPM) applications requiring higher torque capabilities
Not impacted by water, oil, grime, or extreme temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
