Elastomers In Compression
We provides 4 types of elastomer patterns to allow for added versatility in addressing certain application prerequisites. One piece models are used in the “L” and “AL” models (known as spiders) and multiple component “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces dependant upon coupling dimension.
Solid Center Spider
The strong center design and style is frequently used style and design when shafts on the driver and driven tools may be kept separate by a common gap
Open Center Spider
The open center style and design makes it possible for for the shafts of 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 one of several hubs
Snap Wrap Versatile Spider
Style allows for straightforward removal of the spider without having moving the hubs
Makes it possible for for close shaft separation all the way as much as the hubs greatest bore
Optimum RPM is one,750 RPM together with the retaining ring, but if applied using the LC Style (with collar) the regular RPM rating in the coupling applies
Style is available in NBR and Urethane only, and in limited sizes
Spider Components
SOX (NBR) Rubber
The normal materials which is remarkably versatile materials that may be oil resistant
Resembles all-natural rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has one.five instances higher torque capability than NBR
Very good resistance to oil and chemical compounds
Material supplies significantly less dampening effect and operates at a temperature choice of -30° to 160° F
Hytrel
Versatile elastomer created 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 high torque abilities
Not affected by water, oil, dirt, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
