The ball screw is cleaned and completely inspected (See inspection procedure under Ball Screw Reconditioning). Bearing journals are inspected for proper size and critical runout and concentricity to the screw diameter. If the bearing diameters are worn, they need to be corrected for the ball screw to function properly in the machine tool.

Sep 07, 2012 The ball screw design is much efficient for translating rotary motion into linear movement and positioning control, converting roughly 90 of a motor’s torque into thrust. Balls screws achieve this high level of efficiency because the bearing balls transfer and share the load between the nut and the screw.Get Price
If the ball screw is not installed parallel with the table or slide, the ball nut will tighten as it travels towards the ends of the screw, which puts the ball nut under extreme radial load and will cause the ball screw to fail. Some ball screws have adjustable bearing blocks while others use spacers or shims for adjustment. Always have your.Get Price

Apr 06, 2016 The rolling and grinding processes produce different surface finishes. A rough surface finish is problematic in ball screw assemblies because it can result in higher friction and wear on the load carrying balls. The grinding process produces a very smooth surface finish, and in theory, the rolling process does as well.Get Price
2. Place the magnetic base indicator on the ball screw and put the pointer on the bearing support block. Press again. This will show you the movement in the bearings and bearing lock nut.
