How does the Surface Roughness Calculator work?

Measure Ra (average roughness) in micrometers or microinches Then: Typical values: rough (3.2-6.3 μm), normal (0.8-1.6 μm), smooth (0.05-0.2 μm) Then: Specify based on functional requirements.

Can you give an example of how to use the Surface Roughness Calculator?

Example: Input Bearing surface typically requires Ra <0.4 μm (smooth) gives a result of Specify fine grinding or lapping (Affects bearing life).
