Thomson Industries SPTWNM08 Linear Bearing 8mm 500 Lbs

Product Description

The THOMSON INDUSTRIES SPTWNM08 is a closed twin pillow block linear bearing designed for precision linear motion applications. This bearing features an 8mm bore and a dynamic load capacity of 500 pounds, making it well-suited for moderate-duty linear guidance tasks in industrial and automated equipment. The closed housing design provides integrated protection against contaminants, extending service life in environments where dust or debris may be present. It is typically installed by mechanical technicians and machine builders working on linear motion systems, automated machinery, or motion control assemblies.

This bearing is used in applications requiring guided linear motion along a shaft or rail. The closed twin pillow block configuration allows the unit to be mounted directly to a flat surface, with twin mounting points providing stable, rigid attachment. It is commonly found in light industrial machinery, CNC equipment, automation platforms, and similar mechanical systems where consistent shaft alignment and load support are required.

Key Features

• Closed twin pillow block style provides contamination protection for the bearing interior
• 8mm bore diameter for compatibility with 8mm linear shafts
• 500 pounds dynamic load capacity for moderate-duty applications
• Overall length of 62mm with a 50mm center-to-center mounting hole spacing for straightforward mounting layout
• Compact overall dimensions: 35mm wide by 28mm tall, suitable for space-constrained installations

Compatibility

Designed as an OEM-style replacement or direct-fit component for linear motion systems utilizing 8mm diameter shafting in industrial and automated equipment applications.

Installation Notes

Installation is typically performed by mechanical technicians or machine builders familiar with linear motion systems. Before servicing or replacing linear bearings, de-energize all associated drive systems and relieve any mechanical tension on the shaft assembly. Ensure the mounting surface is flat and clean to prevent misalignment that could cause premature wear. Follow applicable machinery safety standards and the equipment manufacturer guidelines during installation.
