Aerotech PRO-SV Long-travel Lift Stages

With a minimum step size of 10 nm, Aerotech's PRO-SV stages are the most precise screw-driven lift stages available—plus they offer the longest travel range available at the shortest height. They’re also the only long-travel lift stages that can move up to 60 kg of mass while providing excellent payload accessibility and geometric performance.

Features:

• Supports 60 kg load capacity, with up to 50 mm travel and 20 mm/s maximum speed
• Delivers excellent straightness & angular performance thanks to high-precision crossed-roller bearings
• Achieves 10 nm step size by combining precision-ground ball-screw, slotless torque motor & low-expansion linear encoder
• Provides long service life thanks to high-reliability drive mechanism
• Integrates seamlessly with PRO-SL and PRO-LM linear stages
• Offers ThermoComp® for consistent performance in changing environments 

Long Travel in a Low-Profile Package

Unlike other types of vertical motion stages, PRO-SV features a drive mechanism that impinges directly on the moving carriage. This provides an exceptionally long range of vertical travel and maintains the shortest height possible, granting free and clear access to the user's payload. Minimising the work-point height is especially important in designing motion systems because it minimizes the Abbe offset, thus contributing to greater overall precision.

Precisely Engineered for Superior Performance

A major problem commonly associated with lift stages is subpar geometric performance (i.e., straightness, pitch, roll, and yaw). PRO-SV provides an innovative solution to this problem. Guided by anti-creep and crossed-roller bearings, the moving carriage is thoroughly supported in all directions, making PRO-SV the most precise commercially-available lift stage on the market. Additionally, a slotless, brushless torque motor is joined directly to a large-diameter, precision-ground ball-screw drive mechanism to position even the heaviest payloads with extremely smooth, cog-free motion. The lack of belts, gears, and flex-couplings contributes to PRO-SV's high reliability and eliminates sources of error from wind-up and excessive backlash.
