Thomson Industries 3/8 L Ctl 7 Round Linear Shaft

Product Description

The THOMSON INDUSTRIES 3/8 L CTL 7 is a standard round linear shaft designed for use in linear motion systems requiring precise guidance and load support. Machined from 1566 grade steel and hardened to a Rockwell C hardness of 60 to 65, this shaft delivers consistent dimensional accuracy with a diameter tolerance held between 0.3740 inches and 0.3745 inches. At 7 inches in overall length and a nominal diameter of 0.375 inches, it suits a range of compact linear motion assemblies. Installation is handled by mechanical technicians and machine builders working with linear bearing systems, slides, and actuator assemblies.

This shaft is suited for residential and commercial mechanical applications where a short, precision-ground linear shaft is needed to support or guide linear bearings, bushings, or carriages. The 7-inch length makes it appropriate for compact assemblies, small automation fixtures, and replacement applications in existing linear motion systems. The hardened steel construction supports repeated loading cycles without significant wear at the shaft surface.

Key Features

• 1566 grade steel construction for durability in linear motion applications
• Rockwell C hardness of 60 to 65 for wear resistance at the bearing interface
• Diameter tolerance of 0.3740 inches to 0.3745 inches for precise fit with linear bearings
• Nominal diameter of 0.375 inches (3/8 inch) and 7 inches overall length
• Standard shaft type suitable for drop-in replacement in compatible linear systems

Compatibility

Designed as an OEM-style replacement or new-build component for linear motion assemblies requiring a standard 3/8-inch diameter hardened steel round shaft.

Installation Notes

This shaft is typically installed by mechanical technicians or machine builders assembling or servicing linear motion systems. Ensure the mating linear bearings or bushings are rated for a 0.375-inch shaft diameter before installation. Clean the shaft and bearing bores thoroughly before assembly to prevent contamination from affecting the tolerance fit. Secure end supports or shaft clamps according to the equipment manufacturer specifications.
