PROPERTIES
Economic solution for bronze bearing application due to a thin wall thickness. High load capability and good stability with low abrasion. Suitable for rough working conditions, good corrosion resistance. Lubrication holes for maximum grease storage and the lowest maintenance intervals.
RANGE OF APPLICATION
Agriculture machinery, truck cranes & construction machinery, suitable for impact loads
MAINTENANCE
BRO-MET®/L is a low maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory. The lubrication holes are an excellent lubrication depot and keeping maintenance to a minimum.
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.
Special dimensions and imperial sizes are available on request
