GLYCODUR® F bearings have good dry sliding properties and do not need lubrication. The presence or supply of oil or other fluids may be advantageous, including other liquids not normally used for lubrication, e.g., water, kerosene or paraffin. Lubrication enhances the removal of heat from the bearing and the formation of a load carrying hydro-dynamic lubricant films result in a considerably enhanced wear characteristic and thus a considerable extension of the service life.
If grease is applied periodically for reasons of sealing or protection of the mating surface against corrosion, this will extend the service life of the bearings. A single application of grease to GLYCODUR F bearings during installation may have a negative effect on the service life, however, as the grease will form a paste-like mixture with the wear particles produced during running-in, which will increase the bearing wear.
Age-resistant lithium-based greases are preferred for lubrication, but at operating temperatures over 80°C (170°F), silicone greases should be used. Greases containing solid lubricant additives (e.g., molybdenum disulfide) are unsuitable.
