The ACL F780 tri-metal material system at the heart of DuraglideTM 780 bearings has been designed for and proven in a wide range of engine applications, both OE and aftermarket. The complimentary layers ensure that superior strength is available from the steel and sintered copperlead-tin lining, accompanied by the excellent anti-seizure properties of the lead-tin-copper overlay. For the engine rebuilder this means confidence - the confidence provided by a tough bearing capable of great performance whether fitted in a garage or precision workshop.
