Application of O-rings in rotary motions In a rotating application a shaft contin-uously rotates in the inside diameter of the O-ring, causing friction and heat. Because rubber is a poor conductor of heat, the O-ring can loose its proper-ties. To minimize or reduce wear, the following could be done; however consult the local ERIKS representative:
