Precision Grinding:The good grinding processing in the outer and inner ring, make the surface smooth and delicate, grinding crack and groove error obviously reduced and touch surface larger.  

6.Bearing oil & grease

Oils – maintain their consistency well over a wide temperature range and are

easy to apply. For very low torque applications, a light instrument oil should be specified. Higher running speeds are possible with oil but the obvious drawback

with oil is the fact that it tends not to stay in place.

Greases – are simply oils mixed with a thickener to so that they stay inside

the bearing. Greases are generally more suitable for heavy loads and have the obvious advantage of giving constant lubrication over a long period without maintenance.
