Jaw Elastomers Overview

Elastomers In Compression
We presents four kinds of elastomer patterns to allow for extra flexibility in addressing distinct application demands. A single piece patterns are used in the “L” and “AL” models (referred to as spiders) and various element “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 dimension.
Reliable Center Spider
The reliable center design and style is normally utilized style when shafts with the driver and driven products can be stored separate by a standard gap
Open Center Spider
The open center layout allows for your shafts of your driver and driven to become positioned inside of a brief distance
Open center spiders give shaft positioning versatility but have a reduced RPM capability
Cushions
Used solely for the C and H Variety couplings
Load cushions are held in area radially by a steel collar and that is connected to one of the hubs
Snap Wrap Versatile Spider
Design and style allows for easy elimination of your spider with out moving the hubs
Permits for close shaft separation the many way as much as the hubs highest bore
Highest RPM is one,750 RPM using the retaining ring, but when applied with the LC Variety (with collar) the standard RPM rating of your coupling applies
Design is obtainable in NBR and Urethane only, and in restricted sizes
Spider Materials
SOX (NBR) Rubber
The common material that’s remarkably versatile material that is definitely oil resistant
Resembles normal rubber in resilience and elasticity, and operates correctly in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.five instances higher torque capability than NBR
Good resistance to oil and chemicals
Material presents much less dampening result and operates at a temperature array of -30° to 160° F
Hytrel
Versatile elastomer designed for substantial torque and large temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert solely for very low velocity (max 250 RPM) applications requiring higher torque capabilities
Not affected by water, oil, grime, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
