PROPERTIES
FER-MAN®259 is a maintenance-free material that is suitable for applications where dust and dirt with a particular hardness and abrasiveness is inevitably paired with high dynamic impact loads. It shows an especially long lifespan in such applications.
RANGE OF APPLICATION
Clamshell for garbage handling machines and underwater applications, crawler chain links, excavator bucket bushings and ladle carriers.
MAINTENANCE
Lubrication is not necessary.
MOUNTING ADVISE
Housing: Mounting bevel min. 1.5 mm x 15-45° Shaft: Mounting bevel 5 mm x 15°, edges rounded
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.
