Spindle ball bearings
 | 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 to 70 mm and 75 to 120 mm (BIGspi)
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

Hybrid bearings
 | Rings and balls from different material Rings made from steel 100Cr6 and balls from ceramics (e.g. silicon nitride Si3N4) Optimized wear behaviour, rigidity, load capacity, speed and life
