Precision Rolled Ball Screws (PSRT Series)

High accuracy (JIS C5) has been achieved by Rolled Ball Screw.
We provide Rolled Ball Screws with high precision & better cost
performance, which can be replaced with conventional
Ground Ball Screw with C5 grade.

Features

  • The conventional type of Rolled Ball Screws can reach the accuracy grade of Ct10 or Ct7.
    ABSSAC newly developed the high grade accuracy of Rolled Ball Screw, which can achieve JIS C5 grade.
  • Fixed side end-journal can be set larger than nominal diameter of Screw Shaft, so there is no need to use Collar by press fit.
  • End-journal profile and dimension are standardized, so ABSSAC Compact Support-Unit can be installed.
  • Since supported-side end-journal is unfinished, it is possible to do additional end machining with your requested thread length.
  • The Axial play is set at 5um or less, but Zero backlash is possible by your request.
  • Special end-journal profile can be available as customized order.
