Fafnir Precision Ball Bearings

Fafnir Precision Ball Bearings

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 Fafnir 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. Fafnir 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.
