Elastomers In Compression
We presents four varieties of elastomer models to allow for more flexibility in addressing certain application needs. 1 piece patterns are used in the “L” and “AL” models (known as spiders) and many component “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.
Solid Center Spider
The sound center style is usually applied design and style when shafts from the driver and driven tools could be kept separate by a common gap
Open Center Spider
The open center layout permits for your shafts of the driver and driven to be positioned inside of a quick distance
Open center spiders offer shaft positioning versatility but have a reduced RPM capacity
Cushions
Employed solely for your C and H Sort couplings
Load cushions are held in place radially by a steel collar that’s connected to on the list of hubs
Snap Wrap Versatile Spider
Style and design will allow for quick removal in the spider without having moving the hubs
Will allow for shut shaft separation all the way as much as the hubs maximum bore
Greatest RPM is 1,750 RPM with all the retaining ring, but when utilized using the LC Type (with collar) the usual RPM rating on the coupling applies
Design is accessible in NBR and Urethane only, and in constrained sizes
Spider Components
SOX (NBR) Rubber
The regular material that is hugely flexible materials that is certainly oil resistant
Resembles pure rubber in resilience and elasticity, and operates properly in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.five times better torque capability than NBR
Very good resistance to oil and chemical compounds
Materials supplies significantly less dampening effect and operates at a temperature variety of -30° to 160° F
Hytrel
Versatile elastomer created for high torque and large temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for minimal velocity (max 250 RPM) applications requiring higher torque abilities
Not affected by water, oil, grime, or excessive temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
