Angular contact ball bearings α0 = 15°/25° - Support of axial load in one direction only - High rigidity and loading capacity, radial and axial, due to higher number of balls - Adjustment against a second bearing is necessary - Size range from 5 mm to 70 mm bore diameter - Precision classes P4/P2 resp. ABEC7 and ABEC9 as well as HG and UP according to GMN factory standard - Suitable for very high speeds Radial deep groove ball bearings - Support of axial and radial loads in both directions - Available in open, single or double shielded execution (depending on cage) - Operation as single bearing (main bearing, radially without play) without separate axial adjustment - Size range from 5 mm to 40 mm bore diameter - Suitable for high speeds
