Unbalance correction by balance weights arrangement -optional

•Unbalance can be corrected by arranging 2 or 3 balance weights on the circumference. This method is popular for balancing of grinding wheels.
•If this method is applied to general industrial machinery, balance correction will be easily done only by rearrangement of balance weights, weight selection and/or fabrication is not needed.
•SB-8802 series can be applied 1 plane(G) or 2 plane(GW) balancing.
