Con-Serv, Inc. - Preformed Fabric Reinforced Elastomeric

The following formula has proven successful in calculating the thickness of the preformed fabric pad to accept a given rotation.
This formula allows for the internal stresses built up in the pad upon rotation.

PF
Thickness Required = ((W/2) x tan a) / "C"

W = width of pad in rotation direction
C = coefficient of friction

CON-SERV Inc recommends an 11 ga. plate be laminated every 2" in pads over 2" thick for strength and stability.
