Thomson Industries SFB12 Flanged Pillow Block Linear Bearing

Product Description

The THOMSON INDUSTRIES SFB12 is a single flanged pillow block linear bearing designed for use in linear motion systems requiring precise shaft guidance and load support. This closed-style ball bushing bearing features a self-aligning design and an engineered-polymer retainer, making it well suited for applications where smooth, low-friction linear travel is critical. The 1.75-inch bore accommodates round shafts and supports a single dynamic load capacity of 600 pounds and a twin dynamic load capacity of 1200 pounds. Weighing 0.75 pounds, this compact bearing unit is installed by mechanical technicians and automation specialists in industrial and commercial equipment builds.

The SFB12 is intended for linear motion assemblies in industrial machinery, automated equipment, and mechanical systems where a flanged pillow block mount is required. The flanged housing allows for direct surface mounting, simplifying installation on frames, plates, and structural supports. The self-aligning bore style accommodates minor shaft misalignment, reducing wear and extending service life in demanding duty cycles. This bearing is appropriate for both new builds and replacement applications in light-to-medium industrial settings.

Key Features

• Closed ball bushing style for full shaft contact and consistent load distribution
• Self-aligning design compensates for minor shaft misalignment
• Engineered-polymer retainer reduces friction and noise during linear travel
• Single dynamic load capacity of 600 pounds; twin dynamic load capacity of 1200 pounds
• Flanged pillow block housing allows direct surface mounting without separate bracket hardware
• Round bore type for use with standard round linear shafting

Compatibility

Designed as an OEM-style replacement or new-installation linear bearing for industrial linear motion systems requiring a 1.75-inch bore single flanged pillow block configuration.

Installation Notes

Installation is performed by qualified mechanical technicians familiar with linear motion systems. De-energize and lock out all power to the machine before removing or installing any bearing components. Ensure the mating shaft is clean, within tolerance, and free of burrs before pressing or sliding the bearing into position. Follow applicable machinery safety standards and the equipment manufacturer's assembly specifications when torquing mounting fasteners.
