English term or phrase: unpolished raceways/unground tracks
What's the difference between these two expressions? I would say no difference, but I could'nt find anything.
Any suggestions? Thanks!

"Inner rings for radial bearings with unground tracks

Inner rings for radial bearings with unpolished raceways"

English translation:no unpolished ~ unground | yes : raceway ~ track
Explanation:
take this example. 1. A bearing race is forged, 2. ground to dimension, and then 3. polished. Certainly there are other ways to do it but between steps one in two you have unground & unpolished, and between steps two and three you have ground & unpolished.

As already mentioned grinding is to establish dimension, and polishing is to harden and smooth a surface. two different processes and objectives.

Raceway and track are to my knowledge synonomous.

they are different mechanical processes.


Explanation:
- polishing gives a smoother finnish comparing with grounding, which is made first in a grinding machine.
