High Speed Grinding Of Spindles Use Ball Bearing 7060AC 300x460x74mm

High speed grinding of spindles use ball bearing 7060AC 300x460x74mm

The four point contact ball bearing 7060ac belongs to single row ball bearing.The bearing types commonly used in high speed grinding spindle are B70C and B70CA series, and B72C and B72CA series can also be used in heavy load. The cage is made of high strength phenolic clamp tube, and the guide of outer ring edge can make the bearing get good lubrication.
