Jaw Elastomers Overview

Elastomers In Compression
We features four forms of elastomer types to permit for more flexibility in addressing certain application necessities. A single piece types are used in the “L” and “AL” models (called spiders) and many component “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 dimension.
Strong Center Spider
The sound center design and style is frequently utilised design when shafts from the driver and driven gear is usually kept separate by a regular gap
Open Center Spider
The open center design and style makes it possible for to the shafts in the driver and driven to get positioned within a short distance
Open center spiders present shaft positioning flexibility but have a decrease RPM capacity
Employed solely to the C and H Sort couplings
Load cushions are held in spot radially by a steel collar which is attached to one of several hubs
Snap Wrap Versatile Spider
Design makes it possible for for quick elimination of the spider without having moving the hubs
Will allow for near shaft separation each of the way up to the hubs greatest bore
Highest RPM is one,750 RPM with all the retaining ring, but when made use of together with the LC Type (with collar) the typical RPM rating with the coupling applies
Type is obtainable in NBR and Urethane only, and in limited sizes
Spider Resources
SOX (NBR) Rubber
The normal materials that is hugely versatile material that’s oil resistant
Resembles natural rubber in resilience and elasticity, and operates proficiently in temperature ranges of -40° to 212° F (-40° to 100° C)
Has one.five occasions better torque capacity than NBR
Very good resistance to oil and chemical compounds
Materials supplies much less dampening result and operates at a temperature variety of -30° to 160° F
Versatile elastomer created for substantial torque and large temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Rigid, porous, oil-impregnated metal insert exclusively for low velocity (max 250 RPM) applications requiring large torque abilities
Not impacted by water, oil, grime, or excessive temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
