Bimetal Bushing aluminum-tin alloy (AlSn20Cu) as a sliding layer. In order to improve tribological behavior the sliding layer can be machined with lubricating grooves for oil- or grease storage and distribution. In case of corrosive environment the backing can be tin plated.Bimetal Bushing,wrapped bushes, thrust washers and bushes in connecting rods of gas engines, etc.
MATERIAL AND COMPOSITION
It has fairly good performance in anti-fatigue and good load capacity, anti-corrosion and smooth sliding movement.
Sliding layer can be machined with lubricating grooves and/or with grease indents
Aluminum-tin alloy for hydraumatic applications.
Liner material: AlSn20Cu
Load capacity: 30N/mm2
Temperature Max: 150℃
Liner hardness: HB30~40
Bearing forms available in standard dimensions
Metric bearings and imperial bushings made to order: standard bushing forms in special dimensions, half-bushings, special shapes obtained by stamping or deep drawing, customized bushing designs
SHAPES & FORMS
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
VIIPLUS advises to use a force fitting mandrel for the installation of the bushing. It might be necessary to apply some grease on the outer surface of the bushing when press fitting it into the housing.
Freeze fitting is suitable for diameter > 130mm, dry ice or liquid nitrogen can be used.
RANGE OF APPLICATION
It usually used as engine bearing with middle or low power, air compressor bushing. It is a good substitution for Babbit material.
