GMN offers a complete range of sizes, types and designs with its spindle ball bearings in standard sizes S, SM and KH. In conventionally oil-lubricated spindle bearings, lubricant is supplied through a lateral oil supply. GMN spindle bearing designs +A, +AB, +L and +LB provide direct oil supplies to the lubrication point through a bore in the outer ring. GMN spindle bearing designs +AG ensure the highest possible machine running times without complex oil supply systems. These feed the lubricant directly into the lubricating point through holes in the outer ring. The developed high-performance, separable BNT and BHT designs ensure fast and uncomplicated handling, especially with regard to assembly and maintenance.

The use of high-precision radial groove ball bearings is especially recommended when axial forces are supported in two directions, but the installation space makes the use of a spindle bearing pair impossible; plus when the best-possible guide for rotating components is needed, but the RPM requirements are less important. Depending upon the load capability and the installation space available, GMN provides deep groove ball bearings in sizes 60 and 62 as per DIN 625. A large selection of various cages, lubricants and covers make it possible to adapt GMN deep groove ball bearings to any application.

GMN high-speed spindles of the HS, HSX, HV-X and UHS series are irreplaceable for grinding work. Whether you must work with holes or frames, with these spindles you always make the right choice. The HV-X and HV-P series are optionally available with a rotational angle sensor, and therefore outstandingly suitable for 4Q operation. The types in the HV-P, HSP and HSP..g series are equipped with an HSK-C holder and furthermore suited for milling and drilling applications. GMN high-speed spindles of the HC, HCS, UHS, HCT series are an essential component of highly-effective machining of various materials. Whether aluminum, steel or titanium, these spindles are optimally designed for all machining tasks which require performance, torque and speed. Using an oil-air or grease permanent lubrication, the spindle bearings operate in a secure fashion.
