| FROM R.{Sir Henry Royce} ORIGINAL RH{R. Hollingworth}/24.2.37. C. to SG.{Arthur F. Sidgreaves - MD} WDH. HS.{Lord Ernest Hives - Chair} HE. W-Da.{Bernard Day - Chassis Design} REX. H-VY. SKEFCO TYPE BEARINGS. K/G52 I do not wish to use the Skefco type of swivel bearings on any of our work, aero and car. Though they are self aligning they will neither take the load or end pressure of a plain deep groove or other type. HY.{Tom Haldenby - Plant Engineer} made rather an extensive test of these some years ago and came to the conclusion - according to my memory - that they were not a good type of bearing. This is the original bearing of the Skefco Co. with its non-grooved, spherical surface, and is the only type of bearing that I thoroughly dislike, except the radial type of thrust bearing running at high speed, which we do not at present use. So you have:- (1) Deep groove. (2) Ordinary bearing. (3) Single and double New Departur. (4) Schatz. (5) The very great favourite - the short roller,(parallel) (6) The bearing we have rarely attempted to use, namely the Timken taper type. We understand this latter to be excellent for heavy loads at slow speeds, such as road wheel work, especially on lorries or other slow and heavy duty, but it has been gaining considerable favour during the last few years.
