• High Precision

  FB Series has lead accuracy C3~C7. It is also possible to adjust axial clearance.
  FB Series can be utilized in various instruments that require high accuracy such as industrial robots, semiconductor manufacturing equipment, and 3D measurement instrument.

• Cost-Effective

  FB Series is a highly cost-effective product even with high precision requirements, because we utilize plastic working when processing the shaft. Traditional cutting and grinding takes more time, so by utilizing plastic working our customers save time and cost.

  *What is plastic working?
  A process which extrudes material into a mold. Advantages of plastic working are increased strength and superior surface smoothness of the shaft.

• Dependable Short Lead Times

  We can deliver products in consistently short lead times due to our large inventory of plastic worked shafts.

• Customize

  We can design and manufacture the size of nut and shaft shape required for your unique specifications.

Example of uses
Industrial robots, semiconductor manufacturing equipment, 3D measurement instrument, lithography, high pressure welding machine etc.
