Applications

Machine tools spindle units

Spindle units have a vital function in machining operations. Discover how Widi products, services and knowledge can help you optimize spindle designs for higher performance and machine uptime.

Factors that go into the machine tool bearings selection process include:

  • Available space
  • Loads (magnitude and direction)
  • Precision and stiffness
  • Speeds
  • Operating temperature
  • Vibration levels
  • Contamination levels
  • Mounting and seal requirements

Bearings for screw drives

Machine tools require screw drives that can position a work piece or machine component quickly, efficiently, and precisely. To meet these requirements, screw drives can be supported at both ends by Widi’s angular contact thrust ball bearings.

The main criteria used when selecting bearings to support screw drives are:

  • Axial stiffness and load carrying capacity
  • Running accuracy
  • Speed
  • Frictional moment (heat generation)
  • Ability to cope with misalignment
  • Mounting and seal requirements
