Dry Self Lubricating Bearings and Bushings EKU/EKF/EKA


The material

The composite material “EKU” consists of three layers: a strip of steel support and a porous bronze matrix (CuSn 10) 0,25 mm of tickness impregnated and coated by material for bearings PTFE annealed at a temperature of 327 ° C.

“EKU” Material properties

The main characteristics of the materials EKU are: - designed to operate without lubrication - excellent sliding behaviour - runs smoothly and quietly with jerky movements negligible - suitable for applications of spin, swing and slide - low coefficient of friction - minimal wear - tolerates dusty environments - no capillary action that draws abrasive particles - chemical resistance - does not accumulate static electricity, making them suitable for use in explosive and flammable environments.

Wear

During the break part of the PTFE coating is transferred to the surface of the shaft resulting in smoothing of the surface. This will have a sliding layer with a low coefficient of friction and low wear. During normal operation, the wear rate increases slowly.

Lubrication

The bearings made of EKU material are used in dry conditions. The regular application of oil or rust compounds can extend the useful life of the bearing by reducing the possibility of corrosion. The bearing life is reduced when it is completely dry or fully lubricated. If you apply the lubricant, the recommended ones are all oils and lubricants used for plastic plain bearings. The lithium-based lubricants without additives MoS2 seem to be the most suitable.
