Splitting A Ball Bearing To Cut Out Backlash
Ball bearings can introduce axial wobble in precision mechanisms due to gaps between balls and races. Chronova Engineering demonstrates a novel approach: splitting a single ball bearing's outer race in half along the circumference, then pressing the two halves together to create a self-contained preloaded bearing. This eliminates the need for paired bearings and avoids thermal expansion issues. Testing on a milling machine feed screw reduced backlash from 0.1–0.2 mm down to 30–40 microns. The technique is related to four-point-contact bearings but is not widely known.
