bearings in the 718 and 719 series are typically used. Bearings in these two series contain the largest number of balls, relative to the selected bore size, and can also accommodate the largest shaft diameter, relative to their outside diameter.
super-precision angular contact ball bearings 718 and 719 series
If a high degree of stiffness is required, bearings in the 718 and 719 series are typically used. Bearings in these two series contain the largest number of balls, relative to the selected bore size, and can also accommodate the largest shaft diameter, relative to their outside diameter. Both characteristics are particularly important for system rigidity, as the rigidity of a spindle increases with its shaft diameter, and the rigidity of a bearing arrangement increases with the number of balls.
