Remarks
  1. The value is for one slide table.
  2. The maximum carrying mass is adjusted by the mass when the rating life of the linear motion rolling guide, ball screws, or bearings is 18,000 hours during continuous operation at a number of revolutions of the motor of 3000min-1 and an acceleration/deceleration time of 0.2s. The mass calculated is based upon the basic static load rating of the linear motion rolling guide.

Remarks
  1. The value is for one slide table.
  2. The maximum carrying mass is adjusted by the mass when the rating life of the linear motion rolling guide, ball screws, or bearings is 18,000 hours during continuous operation at a number of revolutions of the motor of 3000min-1 and an acceleration/deceleration time of 0.2s. The mass calculated is based upon the basic static load rating of the linear motion rolling guide.

TU Features

TU Series is a slim, low-profile positioning table that consists of a U-shaped track rail and a slide table. The slide table assembled inside the U-shaped track rail is an integral part of a linear motion rolling guide mechanism, in which two rows of large diameter steel balls are arranged in four point contact with raceways. Owing to this design, stable, high accuracy motion and high rigidity are obtained in operations even when loads are fluctuating, varying in direction and magnitude, or are complex. Also, by adopting a U-shaped track rail, the rigidity of track rail under moment load and torsion is greatly improved. TU Series includes six sizes with a track rail widths of between 25 mm to 130 mm. For each of them, various slide table lengths can be selected. Also, ball screw types and leads, motor types, and sensor installations, etc. can be selected to obtain an optimum positioning table suitable for each application.
