Self-Lubricating Bearing Materials

TacBEAR self-lubricating PTFE bearing and bushing material is designed to provide a durable, low maintenance and cost effective alternative to its high-performance plastic counterpart.
TacBear’s unique self-lubricating material is constructed by coating one side of an aramid fabric with PTFE. The uncoated side is then bonded to a steel (or other metal) surface. The smooth PTFE surface with its anti-static properties facilitates an easy sliding, friction-resistant bearing or bushing. Additionally, the fabric component improves resistance to cold flow allowing for higher loads.
Taconic can also fusion bond PTFE fabrics and films (filled or unfilled) to a variety of flat sheet stock. Bushings or bearings can then be formed from the flat sheet stock.
