Sintered self-lubricating bearing sleeves, produced by powder
metallurgly method, are intended for operation in hydrodynamic
and semi-fluid friction conditions. Very good sliding properties
of self-lubricating bearings, especially advantageous at low
sliding speeds, swinging and reversible motions, and start-stop
operating conditions, determine their application in many modern
machines and devices.
