Bearing Slide for Mobile Phone

Bearing slides are superior to conventional expansion plates, rollers and rocker arms, accommodating expansion, contraction and other reciprocating motions of any structure that moves as a result of thermal, seismic or differential forces. Normally, a bearing slides consists simply of two pads of PTFE sliding against each other; for very high pressure applications, a single pad may be used to counterface a polished stainless steel plate. The assembly is designed so that one pad(generally the top pad) is larger than the other by an amount in excess of the expected movement, so keeping the contact area constant throughout the cycle of motion.
