Ball bearing / angular-contact / high-accuracy / high-speed
These bearings present the super high speed dn value, 2,100,000 (as dmn value; 2,600,000) using air-oil lubrication. Boundary dimensions are equal to the ISO standard series, but super high speed revolution using air-oil lubrication can be obtained. Bearings also operate under high acceleration conditions.note:
dn = bearing bore diameter in mm x rotational
speed in rpm.
dmn = bearing ball PCD in mm x rotational
speed in rpm.
