Self-lubricating properties from a PTFE & Pb based sliding layer combined with a strong steel backing. DU® has very good wear and friction performance over a wide range of load, speed and temperature conditions. Available in a wide range of standard dimensions and in corrosion resistant bronze backed (DU-BTM). DU® has been the industry standard since its introduction in 1956. Special shapes & dimensions are available to order.
Usage:
Dry = Very good
Oil lubricated = Good
Grease lubricated = Fair
Water lubricated = Fair
Process fluid lubricated = Fair
