Parker 4304 Precision Ball Bearing Linear Stage 50 Lb

Product Description

The PARKER 4304 is a single-axis precision ball bearing linear positioning table designed for light-duty motion control applications requiring smooth, accurate linear travel. The table provides 1 inch of travel and supports a load capacity of 50 pounds, making it suitable for benchtop automation, instrumentation setups, and light manufacturing fixtures. Drive is delivered through a center drive configuration, which promotes even force distribution across the carriage. The table measures 4 inches long by 1.75 inches wide by 0.75 inches high. Installation and adjustment are handled by technicians and engineers working with precision motion assemblies.

This positioning table fits applications where controlled linear motion is needed on a compact footprint. With 16 mounting holes and a 6-32 mount hole size, the table integrates into a wide range of fixture plates, optical breadboards, and machine frames. It is well suited for laboratory automation, quality inspection equipment, light assembly stations, and similar tasks where repeatable positioning matters. The single-axis design keeps the build height low while maintaining rigid support across the full travel range.

Key Features

• 1 inch of linear travel with precision ball bearing carriage for smooth, low-friction motion
• 50 pound load capacity supports tooling, sensors, and light workpiece fixtures
• Center drive configuration distributes drive force evenly along the carriage
• 16 mounting holes with 6-32 thread size for versatile fixture integration
• Compact footprint: 4 inches long by 1.75 inches wide by 0.75 inches high
• Single-axis design maintains low profile in space-constrained assemblies

Compatibility

Designed as an OEM-style precision linear stage for use in single-axis motion control assemblies where a 6-32 mounting interface and 1 inch travel range meet application requirements.

Installation Notes

Installation is typically performed by mechanical or automation technicians familiar with precision motion hardware. Ensure the mounting surface is flat and clean before securing the table to avoid inducing bind or misalignment across the travel range. Use properly sized 6-32 fasteners and torque evenly across the mounting holes in an alternating pattern. Protect the ball bearing carriage from contamination during and after installation, as debris can degrade positioning accuracy over time.
