GMN
High-precision spindles, bearings & freewheels
GMN Paul Müller Industrie, founded in Nuremberg, Germany in 1908, is a precision specialist across five connected product areas, spanning high-precision deep-groove and spindle ball bearings, high-frequency motor and grinding spindles, high-speed electric drives, sprag-type freewheel clutches, and non-contact seals for high-speed shafts. Its bearings and spindles are staples of machine-tool builds where runout and speed matter.
We source and stock the GMN range for machine builders and MRO teams. The spindle ball bearings (angular-contact and high-precision deep-groove) are matched sets built for the rpm and rigidity of a grinding or milling spindle, and GMN's own high-frequency spindles cover grinding, milling, dressing, and workpiece duty with a range of tooling interfaces.
The freewheel clutches (backstops, overrunning, and indexing) and the non-contact labyrinth seals round out a precision-motion portfolio that lets one supplier cover the rotating heart of a machine. When a spindle needs rebuilding, matching the exact GMN bearing set and seal is what restores original accuracy.
Send us the GMN bearing designation or spindle model (or your speed, load, and precision class) and we'll quote the correct bearing set, spindle, freewheel, or seal.
