| -2- these rollers proved to have no preload. We think you will agree that there is a con- siderable difference between working near the lower limit of preload" as agreed to by us and sending in rollers with "no end movement" and which upon our inspection, have no preload. In view of the fact that you sent in one batch which was quite satisfactory it seems to us that your works must be under the impression that we no longer require the pre- load between the specified limits. This is not so. For your information we repeat the preloads which the various roller assemblies should have. Your N.2784 6 - 12 ozs. at 3" radius. " N.2891 6 - 12 ozs. " " " N.2790 4 - 8 ozs. " " " N.2904 4 - 8 ozs. " " We should be glad to receive your comments on this matter. Yours faithfully, for ROLLS-ROYCE LTD. | ||
