Lubrication in general
Oil or grease lubrication
Monorail guidance systems must be lubricated. Technical, economic and ecological factors will determine whether oil or grease should be used and which lubrication method should be applied.
A significant factor in selecting the type of lubrication is the environmental conditions, such as contamination. If extreme conditions are anticipated, it is recommended that Schaeffler External Sales is consulted in the design phase.
Delivered condition, suitable lubricants
RUE..-E and KUSE are protected by a preservative. The preservative is compatible with oils and greases having a mineral oil base.
The series KUVE..-B and KUVE..-W are supplied with basic greasing. Nevertheless, the series KUVE..-B and KUVE..-W must be relubricated with the minimum oil quantity or initial grease quantity before commissioning.
Initial greasing is possible by agreement, in order to supplement the basic greasing. The basic greasing is not a substitute for initial greasing. It is only suitable for bridging the period for commissioning, until the carriages are provided with an initial greasing or are connected to a central lubrication system.
KUVE25-B..-HS (design High-Speed) and KUVS are supplied as standard with an initial greasing (greasing ready for operation).
Monorail guidance systems run exclusively under mixed friction conditions. Doped lubricants should therefore be used in preference (type P to DIN 51502).

Used lubricants
ACHTUNG
Used lubricants should be disposed of by environmentally-friendly methods. The use of lubricants is governed by national regulations for environmental protection and occupational safety as well as guidance from the lubricant manufacturers. These regulations must be observed.
