Timken® Fafnir® super precision ball bearings are designed to meet demanding machine tool requirements for high speeds, accuracy, rigidity and maximum machine uptime. These bearings are manufactured to ABEC 9/ISO P2 running tolerances, the most precise tolerances recognized by the ball bearing industry. Most have contact angles of 15 or 25 degrees for different combinations of radial and axial loads. Special raceway finishes and ball bearing designs achieve the highest possible operating speeds.
