What are the advantages of NSK gas smooth bearings?
NSK gas smooth bearing has a high speed; high precision; conflict loss. Depending on the dreams of the devil, it is ridiculous.
The air film of the NSK gas smooth bearing has the effect of error homogenization; its accuracy is two orders of magnitude higher than that of the rolling bearing; and it oscillates. It means that the è ¡ è ¡ è ¡ è ¡ 冉 è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡ è ¡Î£ Phosphorus throwing æ¹ã• éª leg test.
Smooth gas is generally air or inert gas; not only does it not pollute into the atmosphere; and the bearing has small oscillation and low noise; it does not pollute the environment. The gas static bearing has no direct metal touch; the theoretical life is infinite.
NSK gas smooth bearings have defects?
NSK gas smooth bearing defects have four aspects; first, the bearing capacity is low; second, the reliability is poor; third, the cost is expensive; fourth, the working conditions are severe.

NSK gas smooth bearing scale NSK gas smooth imported bearings are widely used in machine tools; such as for spindle support; including workpiece shaft, tool shaft, grinding wheel shaft, etc.
Generally; machine tool spindle bearings have two types of hydrostatic bearings and dynamic pressure hybrid bearings. Small high-speed spindles can also be used with wave foil bearings. Gas static pressure bearings are most used in machine tools; the savings in small holes and toroidal bearings are the most common. .
These years; porous gas hydrostatic bearings are very popular; far-used for machine tool self-dynamic pressure mixing smooth bearings. These years; newly developed high-speed gas smooth bearings called floating ring dynamic pressure gas bearings; very high-speed spindle support .
