Bushing inner-Ø after mounting

Pls consult our sales engineers, standard delivered tolerance: r6 or E7

Shaft tolerance

f7 or h6 [N/mm2]

SHAFT MATERIAL

The shaft hardness should be at least 70-100HB harder than the bronze alloy. Surface roughness ≤ Ra 0.8

PROPERTIES

LUB-MET® fullfills the highest operational demands and is suitable for shock loads. Depending on the alloy, it is corrosion-resistant and also highly wear-resistant with a long life span.

RANGE OF APPLICATION

Cranes, mining machines, construction machinery, off-shore & marine applications, steel plant, hydro power & hydro mechanical

MAINTENANCE

LUB-MET® is a maintenance-free bearing material, but an initial greasing is mandatory for the "running-in"process. A lithium aging-resistant grease should be used.

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

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.
