Elastomers In Compression
We presents four kinds of elastomer models to permit for added flexibility in addressing unique application specifications. A single piece models are used in the “L” and “AL” versions (known as spiders) and a number of part “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces determined by coupling size.
Solid Center Spider
The strong center style and design is typically employed design and style when shafts on the driver and driven tools is usually kept separate by a normal gap
Open Center Spider
The open center design and style lets to the shafts from the driver and driven for being positioned inside of a short distance
Open center spiders present shaft positioning versatility but have a decrease RPM capacity
Cushions
Used exclusively for the C and H Style couplings
Load cushions are held in area radially by a steel collar and that is connected to among 
the list of hubs
Snap Wrap Versatile Spider
Design allows for simple removal on the spider devoid of moving the hubs
Makes it possible for for near shaft separation the many way up to the hubs optimum bore
Greatest RPM is 1,750 RPM using the retaining ring, but when made use of with the LC Style (with collar) the usual RPM rating from the coupling applies
Design is accessible in NBR and Urethane only, and in limited sizes
Spider Elements
SOX (NBR) Rubber
The standard materials that may be very versatile material that is oil resistant
Resembles organic rubber in resilience and elasticity, and operates efficiently in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has one.5 instances higher torque capacity than NBR
Fantastic resistance to oil and chemicals
Material delivers much less dampening impact and operates at a temperature range of -30° to 160° F
Hytrel
Versatile elastomer made 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 solely for lower 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)
