Spindle Bearings

Spindle bearings are a special type of single row angular contact ball bearings. They can absorb radial forces as well as axial and combined forces and are suitable for highest requirements of guiding and running accuracy, rigidity, increase in speed and decrease in friction due to their very limited tolerances. Spindle bearings cannot be disassembled and are not suitable for compensation of angular misalignments. They are mainly used for bearing the main spindle in the machine tools.

Dimensions and Tolerances

The boundary dimensions of the bearings are standardised in ISO 15, DIN 616, and DIN 628-6. ALPHA Wälzlager GmbH supplies spindle bearings with precision tolerance P4S in accordance to DIN 620-2 and ISO 492. 

Internal Clearance or Preload

Spindle bearings are divided into clearance classes and preload classes. These are not standardised and are defined by suffixes.
