Thomson Industries Qstu 1 L 48 Linear Shaft 1 in 48 in Steel

Product Description

The THOMSON INDUSTRIES QSTU 1 L 48 is a tubular round linear shafting designed for use in linear motion systems and precision positioning applications. Manufactured from steel with a hardness rating of 58 to 63C, this shaft provides the wear resistance and dimensional stability required in demanding motion control environments. It measures 1 inch in diameter and 48 inches in length, with a tolerance of 0.031 inches. At 7.584 pounds, it offers solid structural integrity without excessive weight. Mechanical technicians and industrial maintenance professionals install this component in guided linear assemblies, automated equipment, and machine slides.

This shaft is suited for use in both light industrial and commercial linear motion applications. It fits into bearing and bushing assemblies that require consistent roundness and surface hardness for repeatable travel. Typical installations include linear guides on manufacturing equipment, actuator assemblies, and material handling systems. The tubular construction reduces overall weight compared to solid shafting while maintaining the rigidity needed for guided motion under load.

Key Features

• Tubular round shaft profile reduces weight while maintaining structural stiffness
• Steel construction with 58 to 63C hardness for wear and surface durability
• 1 inch diameter with a 0.031 inch tolerance for precise fitment in linear bearings
• 48 inch overall length suitable for medium-span linear motion assemblies
• Consistent roundness supports smooth, low-friction travel in guided systems

Compatibility

Designed as an OEM-style replacement or direct-fit component for linear motion systems requiring 1 inch diameter round tubular shafting with 58 to 63C surface hardness.

Installation Notes

Installation is typically performed by mechanical or industrial maintenance technicians. Disconnect and lock out all power to the equipment before removing or installing linear shafting. Inspect bearing blocks and support mounts for wear before fitting the new shaft. Avoid using the shaft as a ground path or structural support member beyond its rated linear motion application.
