Jaw Elastomers Overview

Elastomers In Compression
We features 4 types of elastomer styles to permit for supplemental versatility in addressing precise application specifications. 1 piece types are used in the “L” and “AL” designs (referred to as spiders) and a number of aspect “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.
Solid Center Spider
The solid center design and style is generally employed design and style when shafts in the driver and driven tools can be kept separate by a normal gap
Open Center Spider
The open center design and style makes it possible for for the shafts with the driver and driven to become positioned inside a short distance
Open center spiders supply shaft positioning versatility but possess a reduced RPM capacity
Cushions
Utilized exclusively for the C and H Kind couplings
Load cushions are held in area radially by a steel collar and that is connected to one of several hubs
Snap Wrap Flexible Spider
Style and design allows for simple removal of the spider with no moving the hubs
Allows for shut shaft separation each of the way up to the hubs maximum bore
Highest RPM is 1,750 RPM with the retaining ring, but if utilised using the LC Kind (with collar) the normal RPM rating with the coupling applies
Fashion is obtainable in NBR and Urethane only, and in constrained sizes
Spider Supplies
SOX (NBR) Rubber
The conventional material that may be highly versatile material that’s oil resistant
Resembles natural rubber in resilience and elasticity, and operates efficiently in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.five times better torque capability than NBR
Fantastic resistance to oil and chemicals
Material gives significantly less dampening result and operates at a temperature choice of -30° to 160° F
Hytrel
Flexible elastomer designed for large torque and substantial temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for lower speed (max 250 RPM) applications requiring substantial torque abilities
Not affected by water, oil, grime, or severe temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
