SKF bearing rings characteristics

NSK bearing and a fine grit oil-stone with certain pressure workpiece surface to processing, super let is to point to in good lubrication condition, FAG increased to 80% ~ 95% , workpiece rotate at a certain speed, and in vertical direction of rotation to a work as on a concussion movement a processing method. It has the following features:

1. Can effectively reduce the corrugated degrees. Let the process, when oil-stone and workpiece circular contact is equal to or greater than the surface of the wavelength of the striation, can ensure oil-stone always in the role of wave and not and troughs contact, this wave contact pressure is bigger, convex peak was removed, thus reducing the corrugated degrees.

2. TIMKEN bearing can effectively improve the let the groove furrowed error, improve the ball bearing groove of the groove shape error. General improvement in 35% or so.

3. Can be super let surface produces stress. Let the main process of plastic deformation have cold, so the surface of workpiece formed after let residual stress.

4. Reduce the surface roughness.

5. Can make the surface contact area collar job increase. After super , collar work surface contact support area can be grinding of after by 15% ~ 40%.

6. High production efficiency, low labor strength, NTN bearing is easy to realize the automation.
