Thomson Industries Qs 1 1/4 L Pd 54 Linear Shaft

Product Description

The THOMSON INDUSTRIES QS 1 1/4 L PD 54 is a predrilled round linear shaft designed for use in linear motion systems and mechanical assemblies. Manufactured from steel hardened to 60 to 65 Rockwell C, this shaft measures 1.25 inches in diameter and 54 inches in overall length. The predrilled configuration simplifies mounting and reduces setup time in the field. At 18.792 pounds, it is a solid, production-grade component suited for demanding linear motion applications. Mechanical engineers, machine builders, and industrial maintenance technicians are the primary installers of this type of shaft.

This linear shaft is used in applications requiring precise, guided linear motion, including conveyor systems, actuator assemblies, slide units, and automated machinery. The steel construction with Rockwell C 60 to 65 hardness supports high load and wear requirements typical of industrial and light manufacturing environments. The predrilled shaft design is commonly specified when end-mounting or through-bolt attachment is part of the assembly design. This shaft is appropriate for both new machine builds and replacement of worn or damaged linear motion components.

Key Features

• Predrilled shaft type simplifies end mounting and reduces on-site machining
• Steel construction hardened to 60 to 65 Rockwell C for wear resistance
• 1.25-inch diameter with a tolerance of 0.031 inches for consistent fit
• 54-inch overall length suits longer travel linear motion assemblies
• Weighs 18.792 pounds - solid, production-grade stock

Compatibility

Designed as an OEM-style replacement or new-build component for industrial linear motion systems requiring a 1.25-inch diameter predrilled steel shaft with 54-inch overall length.

Installation Notes

Installation is typically performed by mechanical technicians or machine builders familiar with linear motion system assembly. De-energize and lock out all power to the machine before removing or installing any shaft components. Inspect shaft support blocks and linear bearings for wear before installation, and verify bore tolerances are within specification to ensure proper shaft fit. Follow applicable machinery safety standards and manufacturer assembly guidelines for torque and retention hardware.
