The LUMET wear plate, thrust plate and bushing materials are specifically selected for the application involved.
The wear plates, thrust plates and bushings material are provided with solid lubrication, with this feature
incorporate in different configurations, depending on the application involved. The arrangement of the solid
lubricant takes into consideration the direction and type of movement, to ensure lubrication is provided over
the full contact surfaces of the two components involved. Impurities penetrating the bearing surfaces are
absorbed into the solid lubricant pockets, thus displacing lubricant pockets thus displacing lubricant
particles which in turn provides lubrication. In principle however, the penetration of contamination into the
bearing area should be prevented by applying appropriate seals and/or scrapers. Solid lubrication is utilized
at lower speeds, as the frictional heat created cannot be dissipated adequately, for that reason the speed
should be limited. In the case of intermittent movement, higher speeds are possible. The primary factors taken
into consideration in establishing the component material are:
- Bearing load stated as psi, calculated as total
load (lbs.) divided by total surface area ( in sq. inches)
- Speed generally stated in inches per minute or
feet per minute
- Temperature can operate as high as 1100 degrees
F or 600 degrees C
- Design required
