Elastomers In Compression
We presents 4 types of elastomer models to permit for added versatility in addressing specific application specifications. 1 piece designs are used in the “L” and “AL” models (known as spiders) and many part “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.
Reliable Center Spider
The strong center design is generally employed style when shafts on the driver and driven products is usually kept separate by a regular gap
Open Center Spider
The open center design and style will allow to the shafts of the driver and driven to become positioned within a short distance
Open center spiders offer you shaft positioning versatility but possess a lower RPM capacity
Cushions
Used exclusively for the C and H Style couplings
Load cushions are held in spot radially by a steel collar and that is attached to on the list of hubs
Snap Wrap Versatile Spider
Style and design allows for easy elimination in the spider without the need of moving the hubs
Makes it possible 
for for close shaft separation all the way as much as the hubs optimum bore
Maximum RPM is one,750 RPM using the retaining ring, but if used with the LC Style (with collar) the standard RPM rating of the coupling applies
Design is obtainable in NBR and Urethane only, and in limited sizes
Spider Elements
SOX (NBR) Rubber
The standard materials that may be very flexible material that may be oil resistant
Resembles all-natural rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has one.5 occasions better torque capability than NBR
Superior resistance to oil and chemical compounds
Material supplies much less dampening result and operates at a temperature range of -30° to 160° F
Hytrel
Versatile elastomer created for substantial torque and high temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert solely for very low velocity (max 250 RPM) applications requiring large torque capabilities
Not affected by water, oil, grime, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
