Long-travel, high-load motorized Z stages for optical experiments, fine positioning and precision processing.

PSAV series stages lift loads through a ball screw reducer, which has much smaller backlash than a trapezoidal screw reducer and supports very high payloads. Four linear bearing guides keep the 240 × 240 mm aluminum table running smoothly, and five models cover 50 to 400 mm of vertical travel. A two-phase 57 stepping motor with high holding torque drives the stage, with rated loads from 200 kg (50 mm travel) to 100 kg (400 mm travel).

Key Features

  • φ40 × 5 ball screw reducer with 4:1 reduction for high load capacity and low backlash
  • Four linear bearing guides for stable, smooth vertical motion
  • Travel from 50 mm to 400 mm on a common 240 × 240 mm table
  • Rated load from 200 kg (PSAV50-240ZF) to 100 kg (PSAV400-240ZF)
  • Two-phase 57 stepping motor, 1.8°, 2.4 A, 1900 mN·m holding torque
  • Two built-in limit sensors with dry-contact output; DB9 connector

Typical Applications

  • Optical experiments needing long vertical travel
  • Fine positioning of heavy payloads
  • Precision processing and machining setups
  • Lifting platforms for test and measurement equipment
