Extended Contact Ball Bearing Guide


We offer the KSPT series for extended contact ball bearing guide rotation stages, perfect for angular adjust of high loads. For more information or specifications, please check our specifications tab below or contact our experts.

Ultrathin Rotation Stage with Central Aperture

Square footprint of rotation stages with a clear aperture at the center. total stage thickness 10mm. Can be installed in arbitrary orientations such as vertical or inverted due to superior stiffness inherent to the intergrated bearing way design.

  • Ideal for use in systems that require angular adjustment of high loads or that are constrained for space.
  • Low-profile X axis steel stage (TSDT) with stage thickness of 10mm is also available. E016 W7003
  • Opposed clamp locking mechanism standard.
  • The part number suffix FP indicates products with fine-pitch screws instead of standard micrometers. Fine Pitch screws have a screw pitch of 0.25mm and require a hex wrench or the optional hex wrench with knob (KCL) for adjustment.

When installing on a vertical surface, please make sure to place the micrometer head pointing down so that gravity pulls in the same direction as the springs. If the springs oppose gravity, they may not be able to withstand the load and not be able to hold the stage against the micrometer.
