Jaw Elastomers Overview

Elastomers In Compression
We features 4 types of elastomer styles to allow for more flexibility in addressing certain application necessities. One piece designs are utilized in the “L” and “AL” designs (known as spiders) and a number of element “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces based on coupling size.
Reliable Center Spider
The solid center style is frequently utilised layout when shafts in the driver and driven products may be kept separate by a typical gap
Open Center Spider
The open center design and style makes it possible for for that shafts in the driver and driven for being positioned inside of a short distance
Open center spiders supply shaft positioning versatility but have a lower RPM capability
Cushions
Used exclusively to the C and H Kind couplings
Load cushions are held in spot radially by a steel collar that is attached to on the list of hubs
Snap Wrap Flexible Spider
Layout makes it possible for for quick elimination from the spider devoid of moving the hubs
Allows for close shaft separation the many way up to the hubs optimum bore
Greatest RPM is 1,750 RPM together with the retaining ring, but if utilised using the LC Type (with collar) the normal RPM rating with the coupling applies
Style is available in NBR and Urethane only, and in restricted sizes
Spider Materials
SOX (NBR) Rubber
The typical materials that may be really flexible material that is certainly oil resistant
Resembles pure 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 better torque capability than NBR
Fantastic resistance to oil and chemicals
Materials gives less dampening result and operates at a temperature choice of -30° to 160° F
Hytrel
Flexible elastomer intended for substantial torque and high temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for lower velocity (max 250 RPM) applications requiring higher torque capabilities
Not affected by water, oil, dirt, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
