Jaw Elastomers Overview

Elastomers In Compression
We features 4 styles of elastomer designs to allow for added versatility in addressing certain application demands. A single piece models are utilized in the “L” and “AL” models (called spiders) and several portion “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces determined by coupling dimension.
Strong Center Spider
The reliable center style and design is generally used layout when shafts of the driver and driven tools might be kept separate by a regular gap
Open Center Spider
The open center design and style will allow for your shafts of your driver and driven to become positioned inside of a short distance
Open center spiders present shaft positioning flexibility but possess a lower RPM capability
Employed exclusively for the C and H Sort couplings
Load cushions are held in location radially by a steel collar which can be connected to one of the hubs
Snap Wrap Flexible Spider
Style permits for quick elimination in the spider without having moving the hubs
Allows for close shaft separation each of the way as much as the hubs highest bore
Maximum RPM is 1,750 RPM with the retaining ring, but if used together with the LC Style (with collar) the normal RPM rating in the coupling applies
Type is obtainable in NBR and Urethane only, and in limited sizes
Spider Materials
SOX (NBR) Rubber
The standard materials which is really versatile material that is oil resistant
Resembles purely natural rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Has 1.five times higher torque capacity than NBR
Good resistance to oil and chemical compounds
Materials gives much less dampening result and operates at a temperature selection of -30° to 160° F
Versatile elastomer developed for substantial torque and high temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Rigid, porous, oil-impregnated metal insert exclusively for low speed (max 250 RPM) applications requiring substantial torque capabilities
Not affected by water, oil, filth, or intense temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
