  • Surface Roughness Chart: Understanding Surface Finishes

    Ra is a measure of the average length that is between peaks and valleys. It also measures the deviation from the mean line on the surface within a sampling length. On the other hand, Rz helps measure the vertical distance between the highest peak and the lowest valley. It does this within five sampling lengths then averages the distances measured.

  • BEARING REPLACEMENT GUIDE

    To obtain accurate measurements for ball bearings, internal clearance is usually measured by applying a specified measuring load to the bearings. The clearance measured is always slightly larger than the actual bearing internal clearance due to the elastic deformation caused by the measuring load. Actual internal clearance is obtained by correcting the measured clearance .
