CNC Turning Spindle Bearing Change Reconditioning Turning Machine  

Why dont you use induction Heater for bearing insertion. Very easy method. You take big syringe for grease. Any way you are doing a good job

@ 2.11, you were tapping the outer race while fixing on the spindle shaft. Never do this. Your hammering force on the outer race, will travel to the inner race though the balls. This will damage the bearing and will result in premature failure. And also, use a syringe to load the grease. Make a 3 studded screw jack, with which you can easily assemble bearings

It is not good job. Why you don't use bearing heater? Do not hit to bearings like this!
