Thomson Industries SPM08 Closed Linear Bearing 8mm Id

Product Description

The THOMSON INDUSTRIES SPM08 is a closed linear bearing designed for precision linear motion applications in industrial and mechanical systems. Built around an 8mm bore diameter and a 16mm outside diameter, this Super Ball Bushing bearing delivers a dynamic load capacity of 310 pounds. The closed bearing style fully encircles the shaft for maximum support and contamination resistance. With a self-aligning design and four ball circuits, it compensates for minor shaft misalignment and distributes load evenly across the bearing surface. Mechanical technicians and machine builders install this bearing in linear slides, actuators, and guided motion assemblies where reliable, repeatable movement is required.

This bearing is suited for light-to-medium duty linear motion applications in both industrial automation and precision machinery environments. Its compact 25mm overall length makes it appropriate for space-constrained designs. The closed configuration is typically selected for environments where shaft exposure to debris or particulate contamination is a concern. Technicians use this part as a direct replacement in assemblies requiring an 8mm shaft with a 16mm housing bore.

Key Features

• 8mm bore diameter with 16mm outside diameter for compact fitment
• 310 pound dynamic load capacity for reliable load-bearing performance
• Closed bearing style provides full shaft enclosure and contamination protection
• Self-aligning design compensates for minor shaft misalignment
• Four ball circuits distribute load evenly across the bearing
• 25mm overall length suits space-constrained linear motion assemblies

Compatibility

Designed as an OEM-style replacement for linear motion assemblies requiring a closed Super Ball Bushing bearing with an 8mm shaft bore and 16mm housing outside diameter.

Installation Notes

Installation is typically performed by mechanical technicians or machine builders working on linear motion systems. Power down and de-energize all actuators and drives before replacing any bearing. Press the bearing into the housing bore with appropriate tooling to avoid applying load directly to the ball circuits. Ensure the mating shaft is clean, within dimensional tolerance, and free of burrs before assembly.
