At a high level, ground and rolled ball screws appear to function nearly identically within a wide range of mechanical applications. However, the raceway surfaces, which are very similar to traditional machine screw threads found in a typical screw/nut system, are differentiated by the manufacturing process used to create these features.
The top bearing "killers," or causes of damage and premature end of bearing life, are inadequate lubrication, contamination, overload, and improper handling and installation. They affect cylindrical, spherical, needle, tapered, and ball bearings. When they strike, they force companies to pay for ...
