Compact small-angle rotation stages with a sine mechanism for fast, repeatable reciprocating motion.

The SIN series converts the motion of a 1 mm lead ball screw into small-angle rotation through a precision sinusoidal mechanism, giving low backlash and high repeatability in a compact package. Linear slider guides carry the translating element, a pair of angular contact ball bearings supports the rotary table, and the body is rigid black anodized aluminum. The stages suit automation equipment and precision instruments with tight space and weight limits, as well as production lines with short, high-frequency reciprocating moves.

Key Features

  • Sinusoidal mechanism for precise, high-frequency reciprocation over ±9° (SIN18-40) or ±6° (SIN12-60)
  • Small-pitch φ6 × 1 mm ball screw: ≈0.0009° (SIN18-40) or ≈0.00055° (SIN12-60) resolution at 20 microsteps
  • Precision linear slider guides on precision-machined guide surfaces
  • Pair of angular contact ball bearings: axial runout ≤ 5 µm, radial runout ≤ 10 µm
  • Repeatability ≤ ±0.005° and reverse clearance ≤ 0.01°
  • Two built-in limit sensors; DB9 connector with 0.2 m high-flex cable

Typical Applications

  • Small-angle tilt and rotation in automation equipment
  • Precision instruments with limited space
  • High-frequency reciprocating motion on production lines
  • Fine angle tuning of optical components
