Parker 4421 Precision Ball Bearing X-y Stage Table

Product Description

The PARKER 4421 is a precision ball bearing X-Y stage table designed for applications requiring accurate linear positioning in two axes. The center drive configuration delivers smooth, repeatable motion with a 1 inch travel range and a load capacity of 105 pounds. Twelve mounting holes with a 1/4-20 thread pattern provide versatile fixturing options. The table measures 5 inches long by 5 inches wide by 1 inch high, making it a compact solution for benchtop and machine-mounted positioning tasks. Installation is handled by mechanical, automation, and precision motion technicians working in industrial, laboratory, and manufacturing environments.

This X-Y stage is suited for precision positioning applications in industrial automation, optical alignment, laboratory instrumentation, and light machining setups. The dual-axis travel allows controlled movement in both X and Y directions from a single compact platform. The center drive layout supports balanced load distribution across the table surface, which is important when mounting fixtures, sensors, or tooling that require repeatable repositioning. The 1/4-20 mounting hole pattern is a common standard that simplifies integration with existing fixtures and breadboards.

Key Features

• Precision ball bearing construction for smooth, low-friction linear travel
• X-Y stage configuration enables two-axis positioning in a single unit
• 105 pound load capacity supports a wide range of tooling and fixture weights
• 1 inch travel range with center drive for balanced actuation
• 12 mounting holes with 1/4-20 thread pattern for versatile fixturing
• Compact 5 x 5 x 1 inch footprint suits benchtop and machine-frame installations

Compatibility

Designed as an OEM-style precision positioning component compatible with fixtures, breadboards, and machine frames that use standard 1/4-20 mounting hardware.

Installation Notes

Installation is typically performed by mechanical technicians or automation specialists. Ensure the mounting surface is flat and rigid to prevent binding or loss of travel accuracy. Power down any connected actuators or drive systems before mounting or adjusting the stage. Follow applicable machine safety and lockout/tagout procedures per OSHA and facility guidelines when integrating into automated equipment.
