Milling spindle for high loads ball bearing 7056ACDBP5 280*420*65mm
Angular contact ball bearings 7056AC,7056C,7056B have higher limit speed, can bear both radial and axial loads, and can also bear pure axial loads. The axial load capacity of angular contact ball bearings depends on the contact angle.

Angular contact ball bearings used in precision machine tools can be divided into two categories, one for the spindle of machine tools, and the other for
high-speed grinding of spindles and motorized spindles of grinders. Their structures and properties vary according to their uses. Angular contact ball
bearings for machine tool spindles require high rotation accuracy, sufficient stiffness, load-bearing capacity and small occupancy of space. Commonly
used are 70C, 70AC, 70B, 718B, 718AC, 719AC, 719B, 72B, 72AC, 73B and 73AC series. 70 series can bear lighter load, 72 series can bear heavier
load. C means the contact angle is 15 degrees, AC is 25 degrees, and B is 40 degrees.
