Thomson Industries SUPER4 Closed Linear Bearing 60 Lb

Product Description

The THOMSON INDUSTRIES SUPER4 is a closed-style Super Ball Bushing linear bearing designed for precise linear motion applications. With a 0.25-inch bore diameter and 0.5-inch outside diameter, this compact bearing delivers a dynamic load capacity of 60 pounds. It features a self-aligning design and an engineered-polymer retainer with four ball circuits, making it well suited for motion control assemblies where consistent, low-friction travel is required. Installation is handled by mechanical technicians and machine builders working with linear shafting systems.

This bearing is used in light-duty to medium-duty linear motion systems, including automation equipment, instrumentation, and precision positioning assemblies. Its closed bearing style fully encloses the shaft for improved contamination resistance compared to open-style alternatives. The self-alignment feature helps compensate for minor shaft misalignment during assembly, reducing setup time in tight-tolerance applications.

Key Features

• Closed bearing style for improved shaft enclosure and contamination resistance
• 60-pound dynamic load capacity suitable for light to medium linear motion loads
• Self-aligning design compensates for minor shaft misalignment
• Four ball circuits for balanced load distribution across the bearing length
• Engineered-polymer retainer for lightweight construction
• 0.735-inch overall length in a compact 0.75-inch nominal size envelope

Compatibility

Designed as an OEM-style replacement or direct-fit linear bearing for 0.25-inch diameter linear shafting in closed-bore linear motion assemblies.

Installation Notes

Installation should be performed by qualified mechanical technicians familiar with linear motion systems. Before servicing or replacing linear bearings, ensure all machine power and pneumatic sources are fully de-energized and locked out. Press or slide the bearing into its housing using appropriate tooling - do not strike the bearing directly with a hammer, as this can damage the ball circuits or retainer. Verify shaft diameter and surface finish meet the bearing manufacturer's specifications before installation.
