Elastomers In Compression
We features 4 forms of elastomer styles to permit for additional versatility in addressing particular application specifications. A single piece designs are utilized in the “L” and “AL” designs (referred 
to as spiders) and a number of aspect “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces based on coupling size.
Reliable Center Spider
The reliable center design and style is typically used design and style when shafts on the driver and driven tools might be kept separate by a regular gap
Open Center Spider
The open center style enables for your shafts with the driver and driven to get positioned within a quick distance
Open center spiders give shaft positioning versatility but have a reduce RPM capacity
Cushions
Utilized solely for that C and H Form couplings
Load cushions are held in spot radially by a steel collar which is attached to one of several hubs
Snap Wrap Flexible Spider
Style makes it possible for for straightforward removal in the spider without the need of moving the hubs
Will allow for near shaft separation each of the way as much as the hubs optimum bore
Highest RPM is 1,750 RPM together with the retaining ring, but if utilised with the LC Sort (with collar) the regular RPM rating on the coupling applies
Style is obtainable in NBR and Urethane only, and in restricted sizes
Spider Resources
SOX (NBR) Rubber
The typical materials that may be extremely flexible materials that is certainly oil resistant
Resembles pure rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.five instances higher torque capability than NBR
Superior resistance to oil and chemicals
Materials gives much less dampening impact and operates at a temperature selection of -30° to 160° F
Hytrel
Flexible elastomer designed for higher torque and higher temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert solely for reduced speed (max 250 RPM) applications requiring large torque capabilities
Not affected by water, oil, dirt, or severe temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
