The spindles front bearing is a combination hydrostatic and hydrodynamic bearings, that is surrounded by a high-pressure oil-film, that provide high rigidity as well as high vibration damping performance.

Equipped a pressure-switch with interlock function, make sure that reach the specified back-pressure then start up the spindle, that prevents shaft and bearing contact and friction.

Suitable for the cylindrical grinder, plunge or angular type can be select.
