Endcap Circulation


Less impact and noise with Nut
Double screw patented design
Lighter weight
Suitable for
Transmission devices and equipments 


Promote higher speed rotation and extra high Dm-N value (up to 200,000)

Strengthen durability: When operating repeatedly, friction between balls cause heat generation. That may be made balls oxidized or decarburized, and shortened the service life.

Optimized design for high reliability: Use of computer simulation and FEM analysis.
All nuts are covered with bead groove ball so effectively in the same length under the nut; endcap type can maintain higher dynamic loads than external type.

  • FDE Type (Endcap.Double Nut)
  • FSE Type (Endcap.Single Nut)
