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.

RANGE OF APPLICATION

Agriculture machinery, truck cranes & construction machinery, suitable for impact loads

MAINTENANCE

BRO-MET® is a low maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory. The diamond pockets 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

Gluing: Adhesive should not contact the sliding surface!

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
