Jaw Elastomers Overview

Elastomers In Compression
We presents 4 varieties of elastomer models to allow for supplemental flexibility in addressing distinct application specifications. One piece designs are used in the “L” and “AL” designs (called spiders) and a number of portion “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces based upon coupling size.
Strong Center Spider
The reliable center layout is usually employed design when shafts on the driver and driven products might be stored separate by a standard gap
Open Center Spider
The open center design will allow to the shafts on the driver and driven for being positioned inside a brief distance
Open center spiders provide shaft positioning flexibility but have a decrease RPM capacity
Cushions
Used exclusively to the C and H Variety couplings
Load cushions are held in location radially by a steel collar and that is attached to one of the hubs
Snap Wrap Versatile Spider
Layout permits for uncomplicated elimination in the spider devoid of moving the hubs
Will allow for near shaft separation each of the way up to the hubs maximum bore
Highest RPM is 1,750 RPM using the retaining ring, but when utilized with all the LC Kind (with collar) the regular RPM rating with the coupling applies
Design is accessible in NBR and Urethane only, and in restricted sizes
Spider Elements
SOX (NBR) Rubber
The typical material that is certainly highly flexible material that’s oil resistant
Resembles organic rubber in resilience and elasticity, and operates properly in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.5 times higher torque capacity than NBR
Superior resistance to oil and chemicals
Materials presents much less dampening effect and operates at a temperature range of -30° to 160° F
Hytrel
Versatile elastomer intended for substantial torque and substantial temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert solely for lower pace (max 250 RPM) applications requiring large torque capabilities
Not affected by water, oil, grime, or severe temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
