COM-KU®/M is suitable for high load, rotating, oscillating and reciprocating moments under slow speed. It has excellent mechanical properties and fatigue strength. Robust sliding layer and very good wear behavior.
Suspension, defense industry,off-shore applications, hydraulic cylinders, mooring equipment
COM-KU®/M is a maintenance-free bearing material. No lubrication is necessary.
Housing: Chamfer min. 1.5 mm x 15-45°, for easy bushing alignment Shaft: Chamfer 5 mm x 15°, for easy insertion of the shaft
Freeze fitting is suitable for diameter > 130mm, dry ice or liquid nitrogen can be used.
* For higher requirements – e.g. higher temperature ranges – different materials are available in this category.
** The listed values in the material properties are valid for optimal operating conditions. By changing the conditions of application, e.g. an increase in the sliding speed or strain, these values could shift.
