Thomson Industries 1/4 L Ctl 7 Linear Shaft 0.25in Steel

Product Description

The THOMSON INDUSTRIES 1/4 L CTL 7 is a standard round linear shafting component used in linear motion systems across industrial and mechanical applications. This shaft measures 0.25 inches in diameter and 7 inches in overall length, machined from steel with a hardness rating of 60 to 65 HRC (Rockwell C scale). The hardened surface supports accurate, low-friction travel of linear bearings and carriages. Maintenance technicians, machine builders, and motion system integrators typically specify this type of shafting when replacing worn or damaged shaft stock in existing linear assemblies.

This shaft is suited for light-duty linear motion applications in automation equipment, actuators, and slide assemblies. The 0.25-inch diameter and 7-inch length make it appropriate for compact linear systems where precise shaft sizing is required. It is installed as a standalone replacement shaft or as part of a custom-cut linear bearing system in both OEM manufacturing environments and field service repair scenarios.

Key Features

• Standard round shaft profile compatible with matched linear bearings and bushings
• Steel construction with hardness of 60 to 65 HRC for wear resistance and dimensional stability
• 0.25 inch diameter for use in compact linear motion assemblies
• 7 inch overall length provides a ready-to-install replacement without additional cutting in many applications
• Single-piece packaging allows individual replacement without purchasing in bulk

Compatibility

Designed as an OEM-style replacement shaft for linear motion systems requiring a standard 0.25 inch diameter round steel shaft.

Installation Notes

Linear shafting is typically installed by machine builders or maintenance technicians familiar with linear motion systems. Before replacing shaft stock, de-energize all actuators, release any clamping mechanisms, and ensure the shaft supports or end blocks are cleared. Use appropriate shaft support blocks or end supports to secure the shaft and maintain alignment with the linear bearing or bushing assembly. Verify shaft diameter and length tolerances against the existing system specifications before installation.
