Parker 4004-DM Ball Bearing Linear Stage 25 Lb 1 in Travel

Product Description

The PARKER 4004-DM is a single-axis precision ball bearing linear positioning table designed for applications requiring accurate, repeatable linear motion under moderate load. The table features a center drive mechanism and supports up to 25 pounds of capacity across 1 inch of travel. Eight 6-32 threaded mounting holes provide secure, flexible attachment to fixtures, instrument frames, or machine bases. The compact form factor — 1-3/4 inches long by 1-3/4 inches wide by 3/4 inches high — makes it suited for tight-tolerance assemblies where space is limited. Mechanical engineers, automation technicians, and precision instrument specialists are the typical installers.

This linear stage is used in laboratory instrumentation, optical alignment setups, semiconductor inspection equipment, and light industrial automation where controlled single-axis positioning is required. The ball bearing carriage delivers smooth, low-friction motion appropriate for both manual and motorized drive configurations. Its small footprint supports integration into multi-axis stage assemblies or standalone positioning fixtures in research and light manufacturing environments.

Compatibility

Designed as an OEM-style precision linear stage for single-axis positioning assemblies. No specific system or model compatibility was provided in the product data.

Installation Notes

Installation is typically performed by mechanical technicians or automation engineers. Before mounting, ensure the mating surface is clean, flat, and free of burrs to preserve stage accuracy. Use appropriately sized 6-32 hardware and tighten fasteners evenly across all mounting holes to prevent carriage bind or misalignment. Avoid applying lateral loads beyond the rated capacity, as this can shorten bearing life and reduce positioning repeatability.
