CON-SLIDE™ slide bearings are constructed of filled Teflon® (PTFE) bonded to flat rigid back-up steel. CON-SLIDE™ bearings are designed to reduce friction at loaded expansion and contraction joints in bridges, buildings, pipelines, etc. The CON-SLIDE™ material, at thermal expansion and contraction rates, will exhibit little or no wear for the life of the structure./Asset/a1082.jpg
