Spindle bearings - Import export

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.

Spindle bearings are in SLF’s DNA. When it comes to Spindle Bearings we manufacture and design only the very highest quality in large renage of Options. are particularly applicable in scenarios involving machine tool building, as well as scenarios in which the bearing is subject to the most stringent requirements pertaining to precision or permissible speeds contact angle of 15° or 25° available Other contact angle and materials are available e DLR bearings are also available

EWS quality now available for Swiss-type lathes. This new development in driven tools is EWS's response to many customers' requests. The tool systems may appear straightforward at first sight, but their simplicity belies their performance. The design concentrates on the mounting and the spindle concentricity. The requirement profile was developed jointly with an American medical technology company which uses very small drill bits and requires extreme concentricity properties. The spindle bearing technology used with labyrinth seals sets new standards in this field, and is associated with a long service life. Provision has already been made for service. The service centres in Germany, China, Korea and the USA have already been trained in the system and are ready to respond without delay. Third-party brands can also be serviced there at any time.

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.

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.

The axis height of the spindle bearings matches the fixed bearing unit 2407801. The floating bearing units consist of a housing with deep groove ball bearing, which adapts axially to the linear expansion of the spindle.

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.

Based on our many years of experience in developing and manufacturing high-quality machine components, GMN has specialized in the area of high-precision ball bearings as well as the production of high-performance and long-lived deep groove and spindle ball bearings to meet – or even exceed – the highest precision classes P4 and ABEC 7. Certification under international standards ensures the highest precision in the development and manufacturing of GMN ball bearings and guarantees constant, outstanding qualities related to speed suitability, stability and longevity. The broad product range includes a large selection of standard solutions as well as requirements-tailored special designs.
