Jaw Elastomers Overview

Elastomers In Compression
We features 4 types of elastomer styles to permit for additional versatility in addressing specific application needs. 1 piece models are utilized in the “L” and “AL” designs (referred to as spiders) and multiple component “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces based upon coupling dimension.
Reliable Center Spider
The reliable center style is typically utilised style when shafts in the driver and driven gear is often stored separate by a conventional gap
Open Center Spider
The open center layout enables for your shafts in the driver and driven to be positioned inside of a quick distance
Open center spiders offer shaft positioning versatility but possess a lower RPM capability
Cushions
Utilised solely for your C and H Sort couplings
Load cushions are held in area radially by a steel collar which is attached to on the list of hubs
Snap Wrap Flexible Spider
Style and design enables for effortless removal on the spider without the need of moving the hubs
Lets for close shaft separation every one of the way up to the hubs greatest bore
Maximum RPM is 1,750 RPM with the retaining ring, but if applied together with the LC Type (with collar) the normal RPM rating in the coupling applies
Type is obtainable in NBR and Urethane only, and in limited sizes
Spider Supplies
SOX (NBR) Rubber
The conventional material which is hugely flexible materials that may be oil resistant
Resembles purely natural rubber in resilience and elasticity, and operates correctly in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has one.five instances better torque capacity than NBR
Fantastic resistance to oil and chemical compounds
Material presents significantly less dampening result and operates at a temperature selection of -30° to 160° F
Hytrel
Versatile elastomer created for higher torque and high temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert solely for low speed (max 250 RPM) applications requiring substantial torque capabilities
Not affected by water, oil, filth, or excessive temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
