Hanbury - Head Complaints} Grylls Esq. Dear Sirs, REAR AXLE BEARING 35 mm DOUBLE ROW DOUBLE PURPOSE BEARING With reference to your valued communication of the 28th ultimo, regarding the above, we regret that our reply has been unavoidably delayed and trust this will have caused you no inconvenience. We have investigated the question of obtaining a greater capacity on this job, and on our drawing S.5516 we outline alternative schemes, which will we believe, be self explanatory. Scheme .1. outlines a bearing of exactly the same overall dimensions as the present bearing using 19/32" balls instead of 9/16" balls as in the old bearing, but as will be seen from the drawing, owing to the extra size of balls, only eleven per row can be fitted with the result that the increase in capacity is only six per cent. This bearing should normally be quite satisfactory, but we usually prefer to have a greater amount of material behind the ball than is present in the case of the outer rings on this job, and while we should not anticipate any trouble from the fact that this is ENCLOSURE | ||
