Elastomers In Compression
We presents 4 varieties of elastomer types to permit for supplemental flexibility in addressing specific application prerequisites. 1 piece types are utilized in the “L” and “AL” models (called spiders) and various component “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces based on coupling size.
Reliable Center Spider
The solid center layout is frequently used style when shafts on the driver and driven equipment could be kept separate by a common gap
Open Center Spider
The open center style 
and design permits for that shafts of the driver and driven to get positioned inside a short distance
Open center spiders supply shaft positioning flexibility but have a reduce RPM capacity
Cushions
Utilised solely for the C and H Sort couplings
Load cushions are held in location radially by a steel collar which can be attached to on the list of hubs
Snap Wrap Versatile Spider
Design and style enables for simple elimination with the spider with no moving the hubs
Enables for close shaft separation all the way up to the hubs maximum bore
Greatest RPM is 1,750 RPM with the retaining ring, but when used with the LC Kind (with collar) the normal RPM rating from the coupling applies
Style is accessible in NBR and Urethane only, and in limited sizes
Spider Resources
SOX (NBR) Rubber
The common material that is very flexible material which is 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 1.five instances higher torque capability than NBR
Superior resistance to oil and chemical substances
Materials gives significantly less dampening effect and operates at a temperature array of -30° to 160° F
Hytrel
Flexible elastomer designed for high torque and higher 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 large torque abilities
Not impacted by water, oil, filth, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
