Definitions
- the present invention relates to bearing alloys comprismaterials and under the same conditions this figure caning primarily aluminium, zinc and copper. 10 not exceed 280 kg. per sq. cm), is there an increase in the Bearing materials are known which consist of an alutemperature and of the frictional resistance without the miniurn-zinc-copper alloy containing 30% to 66% alushaft being affected and a noticeable increase of wear minium, a copper content which is at least one-sixth and at occurring.
- Shafts of soft steel for example St 50.11
- St 50.11 most one-quarter of the aluminium content present and show no scoring or erosion after 100 hours running within which the remainder is zinc.

- bearing materials of the aluminium-zinc-copper type are The specific weight of the new material lies in general improved by the addition of antimony or tin, or antimony between about 3.6 and 3.8 gm. per cu. cm. and depends and tin.
- the content of antimony may range between 0.05 mainly on the aluminium content.

Sat- The new material can be readily cast in sand moulds isfactory results are obtained if the sum of the copper and and in shell moulds or by die casting. It requires no subtin fraction lies between 8 and 12% preferably 10%. sequent heat treatment. This is however not absolutely necessary. Abearing mate- The chromium content can range up to 3%. Instead rial consisting of 20% aluminium, 60% zinc, 10% copper of chromium, nickel up to 3% may be added. and 10% tin has very satisfactory running properties. Further components of the new material may be silicon,
- bearing materials which have been tested are beryllium and magnesium. Their content individually shown in the following table: should not exceed 3% and altogether 6%.
