Bearings for Swiveling Spindle Heads in Machine Tools

ROBUSTSLIM angular contact ball bearings are designed to meet the needs of machine tool swivel heads.

These bearings achieve the high running accuracy characteristic of ball bearings alongside high moment rigidity on par with crossed roller bearings.

Features

• High running accuracy
  ROBUSTSLIM bearings achieve a rotational runout under 0.5 μm.
• High moment rigidity
  These ball bearings provide the same high level of moment rigidity as crossed-roller bearings.
• Compact
  A specialized design reduces width dimensions by over 35% compared to standard ball bearings.
