To RHC.{R. H. Coverley - Production Engineer} X1020 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}11/KW.28.7.36. Hall's Tin Bearing Alloys. From a conversation we have had with Leylands it appears that they had complete success running R.R.53 as big end bearings, and this rather agrees with our views. It is only on the main bearings where a high percentage of tin is required to avoid picking up. Will you therefore please put in hand one set of Ph.III strap type rod solid bearings, and one set of Bentley big end bearings, in each of the following alloys :- (a) 14% Tin. 1% Antimony. 2% Nickel. 1% Magnesium. .5% Manganese. (b) 3% Tin. 1% Antimony. 2% Nickel. 1% Magnesium. .4% Manganese. We think these harder alloys will be particularly useful in the case of the Ph.III where locating lugs are relied on.
