Bearings for Swiveling Spindle Heads in Machine Tools
NSK provides angular contact ball bearings specially designed for machine tool swivel heads. These bearings match the high-precision processing needed in multi-spindle configurations. In particular, our ROBUSTSLIM high-accuracy low-profile angular contact ball bearings offer high rigidity with low torque.
- High running accuracy and low torque rotation made posible with ball bearings
- High moment stiffness on par with crossed roller bearings
- Specialized design more compact than standard bearings
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.
- 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.
A specialized design reduces width dimensions by over 35% compared to standard ball bearings.
