Jaw Elastomers Overview

Elastomers In Compression
We delivers four kinds of elastomer styles to permit for extra flexibility in addressing distinct application demands. A single piece patterns are utilized in the “L” and “AL” models (referred to as spiders) and many element “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces according to coupling dimension.
Reliable Center Spider
The sound center style is frequently used design when shafts on the driver and driven products can be stored separate by a conventional gap
Open Center Spider
The open center design and style allows for your shafts of your driver and driven to become positioned inside a brief distance
Open center spiders give shaft positioning versatility but possess a reduced RPM capability
Cushions
Made use of solely for the C and H Sort couplings
Load cushions are held in spot 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 with the spider with out moving the hubs
Enables for close shaft separation every one of the 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 with the coupling applies
Design is obtainable in NBR and Urethane only, and in restricted sizes
Spider Materials
SOX (NBR) Rubber
The common material that is remarkably versatile materials 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 capacity than NBR
Superior resistance to oil and chemicals
Material presents less dampening result and operates at a temperature selection of -30° to 160° F
Hytrel
Versatile elastomer built for large 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 abilities
Not affected by water, oil, dirt, or extreme temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
