Ball Screws
Overview
NMT's Ball Screw is produced from the latest tribology (friction control technology), and boasts the world's top level production volume
due to excellent production technology and quality control.
It is also used in machine tools, general machines such as injection molding machines and conveyors, and in special environments such as semiconductor and FPD manufacturing equipment. We are contributing globally to development.
FAQs
Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.
While DGBBs can handle axial loads in both directions, single-row angular contact ball bearings can only receive axial load in one direction.
Seals and shields offer additional protection for bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings, then finally open bearings. NMT uses supplementary designations D, DU, DW, and V (DD, DDU, DDW, VV) for sealed bearings and Z (ZZ) for shielded bearings. No supplementary designations are listed for open bearings.
