Elastomers In Compression
We gives four styles of elastomer designs to allow for more flexibility in addressing specific application specifications. 1 piece patterns are used in the “L” and “AL” versions (referred to as spiders) and various portion “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces determined by coupling size.
Strong Center Spider
The sound center design and style is generally employed style and design when shafts of your driver and driven gear might be stored separate by a normal gap
Open Center Spider
The open center style and design permits for that shafts from the driver and driven for being positioned within a brief distance
Open center spiders provide shaft positioning versatility but have a decrease RPM capacity
Cushions
Applied solely to the C and H Style couplings
Load cushions are held in location radially by a steel collar which can be connected to among the list of hubs
Snap Wrap Versatile Spider
Style enables for quick elimination in the spider with no moving the hubs
Will allow for close shaft separation the many way as much as the hubs optimum bore
Optimum RPM is 1,750 RPM with all the retaining ring, but if employed with all the LC Style (with collar) the typical RPM rating in the coupling applies
Design is accessible in NBR and Urethane only, and in restricted sizes
Spider Components
SOX (NBR) Rubber
The typical material that may be really versatile material that is definitely oil resistant
Resembles normal rubber in resilience and elasticity, and operates efficiently in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has one.five occasions higher torque capacity than NBR
Great resistance to oil and chemical compounds
Materials offers significantly less dampening effect and operates at a temperature variety of -30° to 160° F
Hytrel
Flexible elastomer made for substantial torque and large temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for reduced velocity (max 250 RPM) applications requiring large torque capabilities
Not impacted by water, oil, dirt, or extreme temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
