Thomson Industries Qs 1 L 48 Round Linear Shaft

Product Description

The THOMSON INDUSTRIES QS 1 L 48 is a round linear shaft designed for precision linear motion applications in industrial and mechanical systems. Machined from 1566 grade steel and hardened to 60 to 65 Rockwell C, this shaft delivers the surface hardness and dimensional consistency required for use with linear bearings, bushings, and guide systems. It measures 1 inch in diameter and 48 inches in overall length, with a tight diameter tolerance of 0.9990 to 0.9995 inches. Mechanical maintenance technicians and industrial equipment assemblers are the typical installers of this component.

This shaft is suited for both new builds and replacement service in linear motion assemblies found in industrial automation, packaging machinery, material handling equipment, and similar mechanical systems. Its 48-inch length makes it appropriate for medium-span slide systems and actuator guide rails. The standard shaft type and 1-inch nominal diameter are common across a wide range of linear bearing products used in light to medium industrial environments.

Key Features

• 1566 grade steel construction with hardness of 60 to 65 Rockwell C for wear resistance
• Tight diameter tolerance of 0.9990 to 0.9995 inches for precise bearing fit
• 1-inch nominal diameter by 48-inch overall length for medium-span applications
• Standard shaft type compatible with common linear bearing configurations
• Weighs 13 pounds, suitable for fixed and sliding linear guide assemblies

Compatibility

Designed as an OEM-style replacement or new-build component for linear motion systems requiring a 1-inch diameter steel round shaft with hardened surface finish.

Installation Notes

Installation is typically performed by mechanical technicians or industrial maintenance personnel. Secure all adjacent machinery and de-energize any powered components before removing or installing a linear shaft. Use proper shaft alignment tools to avoid binding against bearings or bushings. Inspect mating linear bearing bore tolerances before installation to confirm correct fit with the 0.9990 to 0.9995 inch diameter range.
