Jaw Coupling Overview
· The most standard fundamental jaw coupling spider is a spider constructed of solid Nitrile Butadiene (Buna N) rubber (pictured at left). This flexible elastomer is oil resistant, resembles natural rubber in resilience and elasticity, and operates effectively in a temperature range of 40 ° to 212 ° F (40 ° to 100 ° C). This rubber is well suited for cyclic loads (stop/start or reversing).
