That's good info, thankyou. I was considering making a housing to hold a seal at the bottom end of the spindle but I'll see what I can find out from Timken before I go any further. The maximum speed of the spindle is about 1400 rpm, not particularly fast but I hadn't considered that it is much faster than wheel bearings typically run. I have a manual for the mill but it shows a different vertical attachment to what I have (it shows the type with a quill). It specifies a #3 grease for the vertical spindle bearings with 2-3 shots monthly only. Interestingly it calls the lube points on the vertical spindle "grease nipples" whereas every other lube point on the machine is referred to as an "oil nipple".
