Thomson Industries 3/4 L Smae L 36 Round Linear Shafting

Product Description

The THOMSON INDUSTRIES 3/4 L SMAE L 36 is a round linear shafting rod machined from steel with a Rockwell 60C hardness rating. It measures 0.75 inches in nominal diameter and 36 inches in overall length, with a tight diameter tolerance band of 0.7490 inches minimum to 0.7495 inches maximum. The shaft features an annealed end treatment. This type of precision-ground shafting is used in linear motion assemblies and is typically installed by mechanical technicians, millwrights, or automation integrators working on guided linear systems.

This shafting is suited for use in linear bearing systems, slide assemblies, and other motion-control applications where consistent shaft diameter and surface finish are critical. The 36-inch length accommodates a range of travel distances in both light industrial and precision automation setups. The annealed end treatment simplifies cutting and machining if field-trimming is required. At 4.5 pounds, the shaft is manageable for single-person installation in most bench or frame-mounted configurations.

Key Features

• Nominal diameter of 0.75 inches with tight tolerance range: 0.7490 to 0.7495 inches
• Overall length of 36 inches for versatile fitment in linear motion frames
• Steel construction with Rockwell 60C hardness for wear resistance under load
• Annealed end treatment allows field machining or cutting without cracking
• Weighs 4.5 pounds - manageable for individual handling and installation

Compatibility

Designed as an OEM-style replacement or drop-in component for linear bearing systems and slide assemblies requiring a 0.75-inch diameter steel shaft.

Installation Notes

Installation is typically performed by millwrights, mechanical technicians, or automation integrators. Ensure the mating linear bearings or bushings are rated for a 0.75-inch shaft diameter before installation. Support both ends of the shaft during mounting to prevent bowing under clamping force. If field-cutting is required, use appropriate metalworking tools and deburr cut ends before assembly.
