Parker 3922 Precision Ball Bearing X-y Stage Table

Product Description

The PARKER 3922 is a precision ball bearing X-Y stage table designed for linear positioning applications requiring high accuracy and repeatability. It features a center drive configuration with a 1/2 inch travel range and supports a load capacity of 6 pounds. The table measures 1.25 inches long by 1.25 inches wide by 0.5 inches high, making it suited for compact installations. Six 4-40 threaded mounting holes provide secure, versatile attachment. This type of component is typically installed by mechanical engineers, automation technicians, and precision instrument technicians working in laboratory, metrology, or light industrial environments.

The PARKER 3922 fits applications that demand controlled, fine-resolution movement along two axes. Its compact footprint and center drive design make it appropriate for optical bench setups, inspection stages, microscope positioning platforms, and similar precision motion assemblies. The 4-40 mounting hole pattern accommodates standard hardware used across a wide range of precision instrument configurations. The 6-mounting-hole layout distributes clamping load evenly, supporting stable positioning under rated capacity.

• 6 pound load capacity supports typical light-duty staging needs
• Six 4-40 threaded mounting holes with 0.75 inch center-to-center spacing
• Compact form factor: 1.25 inches long x 1.25 inches wide x 0.5 inches high

Compatibility

Designed as an OEM-style precision positioning component compatible with systems and fixtures using 4-40 mounting hardware in X-Y stage configurations.

Installation Notes

Installation is performed by mechanical or instrumentation technicians familiar with precision linear motion assemblies. De-energize and lock out any powered system before mounting or adjusting the stage. Use calibrated 4-40 fasteners and avoid over-torquing, which can distort the bearing race and degrade travel accuracy. Verify axis alignment with a dial indicator or equivalent metrology tool before placing the assembly into service.
