Benchtop Machine Shop: Mill: Spindle Bearings

Apr 10, 2019For a mini lathe or mini mill using AC bearings, about 1 in/lbs is good, and I'd estimate a range of 0.6-1.5 in/lbs being acceptable. Since grease can effect the breakaway torque I'll turn the spindle in the opposite direction I'm going to measure and then turn it back just slightly and then measure.Get price

Mini Mill Y

You will have to mill approximately 0.060" (~1.5mm) off the existing shaft key to make room for the new assembly. The shorter shaft key does not affect performance, as the bearing reduces the amount of torque required to move the axis. This mod should work with all Sieg X2 derived mini mills – Harbor Freight, Grizzly, Homier, etc.Get price

Ball Bearings

Ball bearings, or deep-groove bearings, extend the working life of equipment by enabling wheels, pulleys, and other rotating parts to reduce friction and move smoothly. Ball bearings have a series of round balls encased in a housing and support high axial or low-to-moderate radial loads. Axial (thrust) bearings support loads parallel to the Get price

May 01, 2017Moreover, compared to the roller bearings, they run cooler and generally have higher RPM rating. Part numbers for Mini Mill's stock bearings are 6007 and 6206 for bottom and top bearings respectively. The first digit designates the series. In this case 6 is for radial bearings; angular contact bearings are series 7, so I need 7007 and 7206.Get price

What is the best AR milling machine to finish an 80% lower

Oct 14, 2015I knew nothing about milling before I bought a LMS mini mill. But I didn't mind learning. Always wanted to and figured the 80% game would make learning to mill a little more fun. It certainly wasn't easy to get started. But with enough time, effort and practice, it is pretty easy to produce a quality lower from an 80%.Get price
