Jaw Elastomers Overview – V Pulley

Elastomers In Compression
We delivers 4 kinds of elastomer styles to permit for supplemental flexibility in addressing precise application requirements. A single piece designs are utilized in the “L” and “AL” versions (known as spiders) and several component “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces depending on coupling dimension.
Reliable Center Spider
The solid center design is generally utilised design and style when shafts of your driver and driven equipment may be stored separate by a regular gap
Open Center Spider
The open center style and design allows for that shafts of your driver and driven to become positioned inside a short distance
Open center spiders give shaft positioning versatility but possess a reduced RPM capability
Cushions
Utilised exclusively to the C and H Type couplings
Load cushions are held in spot radially by a steel collar that is connected to among the list of hubs
Snap Wrap Versatile Spider
Layout allows for uncomplicated removal of your spider without the need of moving the hubs
Makes it possible for for close shaft separation the many way as much as the hubs greatest bore
Maximum RPM is one,750 RPM together with the retaining ring, but when utilized together with the LC Kind (with collar) the standard RPM rating with the coupling applies
Fashion is obtainable in NBR and Urethane only, and in restricted sizes
Spider Resources
SOX (NBR) Rubber
The standard materials that is definitely remarkably flexible materials which is oil resistant
Resembles pure rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.5 occasions higher torque capability than NBR
Great resistance to oil and chemical substances
Materials delivers much less dampening effect and operates at a temperature array of -30° to 160° F
Hytrel
Versatile elastomer developed for large torque and higher temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for very low speed (max 250 RPM) applications requiring high torque capabilities
Not affected by water, oil, filth, or severe temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
