Thomson Industries SSUTWN12 Twin Pillow Block Bearing

Product Description

The THOMSON INDUSTRIES SSUTWN12 is a closed twin pillow block linear bearing designed for precision linear motion applications. It features a 0.75 inch (19.05 mm) bore diameter and a ball bushing construction that supports both single and twin dynamic load capacities of 1130 and 2260 pounds respectively. Built from steel, this bearing block is suited for machine builders, maintenance technicians, and industrial service professionals who require a reliable, self-aligning linear motion component. The closed housing style protects the internal ball bushing from contaminants, making it appropriate for moderate-duty environments where debris or particulate exposure is a concern.

The SSUTWN12 is used in linear motion assemblies found in industrial machinery, automated equipment, and mechanical actuation systems. The twin pillow block configuration spans a center-to-center bore length of 4.5 inches, providing stable support across a shaft. This bearing is appropriate for use wherever a round-bore, self-aligning twin block mount is required along a linear shaft of 0.75 inches nominal diameter. The closed style makes it a practical choice when compared to open configurations in lightly contaminated environments.

Key Features

• 0.75 inch round bore accommodates standard 3/4 inch linear shafts
• Ball bushing twin pillow block design provides dual-point shaft support
• Closed housing style shields internal components from particulate contamination
• Self-aligning configuration compensates for minor shaft misalignment
• Steel body construction for strength and durability in industrial service
• Single dynamic load capacity of 1130 lbs; twin dynamic load capacity of 2260 lbs

Compatibility

Designed as an OEM-style replacement or direct-fit component for linear motion systems requiring a closed twin pillow block bearing with a 0.75 inch bore diameter and 4.5 inch center-to-center bore spacing.

Installation Notes

Installation is typically performed by mechanical technicians or machine maintenance personnel familiar with linear motion systems. De-energize and lock out all power to the machine before removing or installing this bearing block. Ensure the mating linear shaft is clean and within dimensional tolerance before seating the bearing. Follow applicable machinery safety standards and the equipment manufacturer's alignment procedures when mounting the block to its base plate.
