Properties of sliding bearing material

Friction and Running-in Characteristics

Friction

The friction in GLYCODUR® bearings mainly depends on the bearing load, the sliding velocity and the operating temperature. The surface roughness of the mating surface and, above all with GLYCODUR® A bearings, the lubrication conditions are also important. The coefficient of friction for GLYCODUR® F bearings is between 0.03 and 0.25 depending on the operating conditions.

The coefficient of friction for GLYCODUR A bearings is similar, but lubrication has a stronger effect in this case.The lower coefficients of friction are typically obtained under high specific bearing loads and low sliding velocities (see diagram). Under extremely unfavorable conditions, as well as with low loads the indicated value may even be exceeded. GLYCODUR bearings show negligible “stick-slip”.




Guidelines for friction coefficients for GLYCODUR F bearings

Running-In characteristics

During the running-in phase of GLYCODUR F bearings one part of the polytetrafluoroethylene top layer will be transferred to the mating surface. For this reason, the characteristically low operating values for wear and friction will be obtained with GLYCODUR F bearings after they have been run-in.
