Thomson Industries Qs 1/2 L 24 Round Linear Shaft

Product Description

The THOMSON INDUSTRIES QS 1/2 L 24 is a standard round linear shafting rod designed for use in linear motion systems, precision slides, and bearing-supported assemblies. Machined from 1566 grade steel, this shaft measures 0.5 inches in diameter and 24 inches in overall length. The diameter is ground and held to a tight tolerance of 0.4990 to 0.4995 inches, ensuring consistent fit with linear bearings and pillow block assemblies. Surface hardness runs 60 to 65 Rockwell C, providing the wear resistance required in industrial and mechanical motion applications. Maintenance technicians and machine builders install this type of shafting during new builds and component replacements.

This round linear shaft is suited for residential and light industrial linear motion equipment, including actuators, drawer slides, automated equipment, and material handling systems. Its standard 0.5-inch diameter and 24-inch length make it a common replacement or build-specification shaft in applications where a hardened, ground steel rod is required. The standardized dimensions allow compatibility with off-the-shelf linear bearings and bushings sized for 0.5-inch shafting.

Key Features

• 1566 steel construction with 60 to 65 Rockwell C surface hardness for wear resistance
• Ground diameter held to 0.4990 to 0.4995 inches for precise bearing fit
• 24-inch overall length suits a wide range of actuator and slide frame lengths
• Standard 0.5-inch shaft diameter compatible with common linear bearing stock sizes
• Weighs 1.75 pounds, appropriate for hand-installation without lifting equipment

Compatibility

Designed as an OEM-style replacement or build-specification component for linear motion assemblies requiring a standard 0.5-inch diameter hardened steel shaft.

Installation Notes

Installation is typically performed by mechanical technicians or machine builders. Secure all equipment and de-energize any actuators or drives before removing or installing shafting. Use appropriate shaft clamps, end supports, or pillow blocks rated for the shaft diameter to ensure correct alignment. Cutting to length, if required, should be performed with tooling rated for hardened steel stock.
