Velmex A4009P40-S4-TL UniSlide Linear Positioner

The Velmex A4009P40-S4-TL UniSlide Linear Positioner is a precision manual positioning system component designed for repeatable, accurate linear motion in laboratory automation, optical alignment, metrology, and semiconductor tooling. It provides 5 inches of travel with a 0.025 inch lead screw per revolution and features a Thumbscrew Lock for secure positioning, making it ideal for research instrumentation, calibration setups, and custom motion systems that require fine, repeatable movement. The unit supports substantial horizontal and center loads for a manual stage: up to 100 lb horizontal load, up to 100 lb horizontal center load, up to 50 lb vertical center load, and up to 40 lb normal load, with a cantilevered moment rating of 130 lb-in. Its footprint includes a base of 10 in by 4 in by 1 in and a carriage measuring 4 in by 2.25 in, with carriage mounting holes specified as #10-32 UNF. This UniSlide is commonly used for replacement and retrofit in optical inspection systems, microscopy equipment, metrology stations, and precision measurement applications, and is well-suited for system integrators, OEMs, and engineers seeking reliable, manual motion control in instrumentation and test fixtures.
