surface texture on a shaft

[nyvens]

hi!

how can surface texture on a shaft be important?
lets say for a rotating shaft connected to a bearing. How can different surface finish on the shaft affect the shaft/bearing assembly? And in practical/real situations where can that be seen?

many thanks

Depending on the type of bearing, materials, speed and lubricant the answer will vary. More detail is important.

Well, ball bearing, mild steel shaft, lubricant: grease, motor-2850rmp.
