Repair of spindles and motor spindles fitted with FAG bearings
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of FAG spindles and motor spindles — the world benchmark brand for very high precision machine tool spindle bearings, part of the Schaeffler group.
FAG, the benchmark spindle bearings of the Schaeffler group
TLDR: FAG, a brand of the German Schaeffler group, offers single-row angular contact spindle bearings of very high precision, whose extremely tight tolerances make them the benchmark for the main spindle bearings of machine tools demanding the highest guidance accuracy.
FAG, a historic brand of the Schaeffler group, produces very high precision spindle bearings — single-row angular contact ball bearings whose extremely tight tolerances make them particularly suited to applications demanding the highest guidance accuracy, such as machine tool main spindle assemblies. These bearings are available in every configuration relevant to main spindle assemblies, with universal design bearings that can be mounted in any arrangement or combined into different sets with no loss of performance. For decades, Schaeffler products under the INA and FAG brands have successfully equipped rotary table bearings, drive spindles, main spindles and axes of machine tools worldwide, making FAG one of the unavoidable references when overhauling a spindle or motor spindle.
One piece of history many workshops are unaware of: FAG was for a long time a spindle manufacturer in its own right, before selling that activity to Weiss. Original FAG spindles and motor spindles are therefore still running in many machine fleets, and we handle them just as we handle spindles fitted with FAG bearings — two distinct situations that are best not confused at the diagnosis stage. For spindles from the business that took over this activity, see our Weiss page.
A range of ceramic ball and high-speed spindle bearings
TLDR: FAG spindle bearings are available with steel or ceramic balls (hybrid bearings), in open, sealed or Direct Lube versions for extremely high speeds, with series dedicated to high speed (HCS70, HCS719) offering reduced friction and longer service life.
FAG spindle bearings are available with steel or ceramic balls (hybrid design), with rings in standard bearing steel or high-performance steel, in open or sealed versions, and in Direct Lube design for extremely high speeds. The high-speed spindle bearings of the HCS70 and HCS719 series, fitted with smaller diameter ceramic balls, allow higher speeds while reducing friction and heat generation, putting less strain on the lubricant for a longer service life. Bearings with integrated seals are lubricated for life with a high-performance FAG grease and require no maintenance, while the X-life ultra range, with stainless steel rings, meets the most severe requirements for vibration resistance and load capacity.
