PROPERTIES
COM-KU®/D has good sliding properties, suitable for high load capacity esp for impact and edge loads, good chemical resistance, long life-span, good damping features.
RANGE OF APPLICATION
Marine and off-shore industry, hydro power, hydro mechanical, pipe laying,
MAINTENANCE
COM-KU®/D is a maintenance-free material, however greasing with lithium based age resistant lubricants can enhance the bearing life.
MOUNTING ADVISE
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.
CAPTION
* 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.
