At what temp should one get concerned about the temp of Babbitt shells on spindle.
Was using 18” Lehmann for roughly 2 hrs continuously (4 five minute stops to change work pieces) turning down some extremely deeply hardened IH semi axles. When I went to shut it down I rested my hand on rear bearing in passing and it was borderline too hot to stay there. Got temp gun and front bearing was 97 and rear was 145ish. Ambient air temp was 92.
Near noticed this before and the oilers were working. Should I be worried?
