Thomson Industries Qsss 1/2 L 60 Linear Shafting

Product Description

The THOMSON INDUSTRIES QSSS 1/2 L 60 is a round linear shafting rod manufactured from 440-C stainless steel, designed for use in linear motion systems and precision mechanical assemblies. The shaft measures 0.5 inches in diameter and 60 inches in overall length, with a tight diameter tolerance range of 0.4990 to 0.4995 inches. Surface hardness is rated at 50 to 55 Rockwell C, providing the wear resistance required for bearing-guided linear motion applications. This shafting is installed by mechanical technicians, millwrights, and industrial maintenance professionals working on linear slides, actuators, and guide systems.

This shaft is suited for residential and commercial linear motion applications including linear bearings, bushings, and support rail assemblies. The 440-C stainless steel construction makes it appropriate for environments where corrosion resistance is a priority alongside mechanical hardness. The 60-inch length accommodates longer-travel linear motion setups and can be cut to length in the field as required by the application. Standard installation involves mounting within linear bearing blocks or support rails as part of a guided motion assembly.

Key Features

• 440-C stainless steel construction for corrosion resistance and surface hardness
• 50 to 55 Rockwell C hardness for wear resistance in bearing-contact applications
• Tight diameter tolerance of 0.4990 to 0.4995 inches for precise linear bearing fitment
• 60-inch overall length supports longer-travel linear motion configurations
• Standard shaft type compatible with common linear bearing and support rail systems

Compatibility

Designed as an OEM-style replacement or new-installation component for standard linear bearing systems requiring a 0.5-inch diameter round shaft in 440-C stainless steel.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians familiar with linear motion systems. Disable all power and relieve any spring or mechanical load from the linear assembly before removing or inserting shafting. Use appropriate shaft support rails and end blocks to prevent deflection along the 60-inch span. Avoid using the shaft as a structural beam without verified support spacing for the applied load.
