Elastomers In Compression
We delivers four forms of elastomer styles to permit for extra flexibility in addressing precise application prerequisites. A single piece styles are used in the “L” and “AL” models (referred to as spiders) and numerous aspect “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 solid center design is generally used design and style when shafts of the driver and driven tools could be kept separate by a standard gap
Open Center Spider
The open center design and style enables for the shafts in the driver and driven for being positioned within a short distance
Open center spiders give shaft positioning versatility but have a reduced RPM capability
Cushions
Utilized solely for the C and H Style couplings
Load cushions are held in area radially by a steel collar which can be attached to among the hubs
Snap Wrap Flexible Spider
Design and style permits for uncomplicated removal with the spider devoid of moving the hubs
Lets for shut shaft separation all the way up to the hubs highest bore
Greatest RPM is one,750 RPM with the retaining ring, but if utilised together with the LC Kind (with collar) the standard RPM rating of the coupling applies
Type is obtainable in NBR and Urethane only, and in limited sizes
Spider Components
SOX (NBR) Rubber
The normal material that is certainly extremely flexible material that may be oil resistant
Resembles natural rubber in resilience and elasticity, and operates effectively in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.5 occasions higher torque capability than NBR
Good resistance to oil and chemical compounds
Materials gives much less dampening result and operates at a temperature selection of -30° to 160° F
Hytrel
Flexible elastomer intended for substantial 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 abilities
Not impacted by water, oil, grime, or extreme temperatures – operates in temperatures of -40° to 450° F (-40° 
to 232° C)
