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

• 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

• 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

• Bearings with rings or cages varying from
  standard dimensions
• Secial bearings such as
  - Touchdown bearings for magnetic bearing systems
  - Vacuum applications (e.g. electron microscopy,
    turbomolecular pumps)
  - Aviation and spaceflight, semiconductor production
    technology
  - Medical technology / X-ray
  - Measurement and navigation technology
  - Bearing units
  - Machine tool applications
• Dry lubrication in GMN's own PVD Sputter system
• Assembled ready-to-install precision bearing units
• GMN develops and assembles ready-to-install precision bearing units - up to series production maturity
