Composite plain bearing AW-50
Galvanized steel/PTFE
Plain bearing made of composite material with galvanized steel backing, sintered bronze and PTFE running layer without lead additives.
-
Plain bearing made of three-layer composite material (backing, sintered bronze, PTFE sliding layer), self-lubricating, maintenance-free and ready to install. Design in accordance with ISO 3547 (DIN 1494). Used for high bearing pressures and low sliding speeds, dry running with low coefficient of friction and low wear, can also be used for lubricated bearing points. Good chemical resistance. Suitable for rotation, oscillation and axial movements. No tendency to weld with metal.
