Spindle bearing preload - Practical Machinist
Jun 10, 2019· My test for correct spindle pre-load on small lathes was to use a 3ft crowbar first of all behind the chuck back face or the spindle flange and prise outwards using moderate pressure. With a DTI set on the bed with the plunger against the chuck front face or spindle flange I would expect to see movement of about 0.001" to 0.0015".
