Fafnir super precision ball bearings are designed to meet demanding machine tool requirements for high speeds, accuracy and rigidity. These bearings are available manufactured to ABEC-7 and ABEC-9 tolerances, the most precise tolerances recognized by the ball bearing industry.
Most super precision ball bearings have contact angles of 15° or 25° for different combinations of radial and axial loads. Special raceway finishes and ball bearing designs achieve the highest possible operating speeds.
Hybrid ceramic bearings are available with steel rings and ceramic balls for special applications involving high speeds and other demanding requirements.
Ballscrew support bearings are supplied in sets with 60° contact angles and a maximum ball complement for the high capacity and axial rigidity required for the most precise tool positioning.
Typical Applications
High-speed grinding
High-speed boring and milling
Precision vertical and horizontal milling spindles
