Project Description

Bimetal Bushing Steel backed bronze Bushings carring a sintered tin-lead-bronze alloy (CuPb30) as a sliding layer.

MATERIAL AND COMPOSITION

Materiai:Steel+CuPb30

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 copper plated.

BEARING PROPERTIES

Liner material: CuPb30

Load capacity: 25N/mm2

Temperature Max: 170℃

Liner hardness: HB30~45

RANGE OF APPLICATION

When soft alloy is plated on the bushing surface, it can be applied under high speed and middle load working situation, just like engine main bearing, connect-rod bushing, rocket arm bushing and oil pump side plate.

AVAILABILITY

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

Cylindrical bushes

Flanged bushes

Thrust washers

Flanged washers

Sliding plates

ASSEMBLY 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

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.
