Elastomers In Compression
We gives 4 kinds of elastomer patterns to allow for added versatility in addressing certain application prerequisites. One piece designs are used in the “L” and “AL” models (known as spiders) and numerous element “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces determined by coupling size.
Strong Center Spider
The strong center design and style is frequently used design when shafts on 
the driver and driven tools may be kept separate by a typical gap
Open Center Spider
The open center style and design lets for your shafts from the driver and driven to be positioned within a short distance
Open center spiders give shaft positioning flexibility but have a reduced RPM capacity
Cushions
Used exclusively for the C and H Kind couplings
Load cushions are held in place radially by a steel collar which can be attached to among the list of hubs
Snap Wrap Versatile Spider
Style allows for effortless removal of the spider without having moving the hubs
Makes it possible for for close shaft separation all of the way up to the hubs maximum bore
Highest RPM is one,750 RPM together with the retaining ring, but if made use of using the LC Style (with collar) the regular RPM rating on the coupling applies
Fashion is available in NBR and Urethane only, and in limited sizes
Spider Components
SOX (NBR) Rubber
The normal materials that is certainly remarkably versatile materials 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.five instances higher torque capacity than NBR
Very good resistance to oil and chemical compounds
Materials delivers less dampening effect and operates at a temperature range of -30° to 160° F
Hytrel
Versatile elastomer made for large 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 higher torque abilities
Not affected by water, oil, dirt, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
