Nb Swf 12GWUU Round Flanged Double Linear Bearing

Product Description

The NB SWF 12GWUU is a round flanged double linear bearing designed for precision linear motion applications. With an inside diameter of 0.75 inches and an outside diameter of 1.25 inches, this bearing supports smooth, low-friction linear travel along a shaft. The overall length measures 3.09 inches and the flange width is 2.19 inches, making it suitable for applications where a flanged mounting face is required for secure positioning. Licensed mechanical technicians and machine builders typically install this bearing in linear guide assemblies, automation equipment, and industrial machinery.

This bearing is well-suited for light to medium-duty linear motion systems in both industrial and commercial settings. The round flanged double configuration provides two bearing circuits in a single housing, distributing load across a greater contact area compared to a single-circuit design. Typical installations include linear actuators, slide assemblies, and positioning stages where shaft diameters of 0.75 inches are used.

Key Features

• Round flanged double bearing type for increased load distribution across two bearing circuits
• Inside diameter of 0.75 inches fits standard 0.75-inch linear shafts
• Outside diameter of 1.25 inches with overall length of 3.09 inches
• Flange width of 2.19 inches enables secure face-mount installation
• Compact, self-contained housing simplifies integration into linear motion assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit linear bearing for precision linear motion systems using 0.75-inch diameter shafts in industrial and automation applications.

Installation Notes

Installation is typically performed by qualified mechanical technicians familiar with linear motion systems. Before servicing, power down and de-energize all connected equipment. Ensure the mating shaft is clean, free of burrs, and within the specified diameter tolerance before pressing or sliding the bearing into position. Do not force the bearing onto an out-of-tolerance shaft, as this can damage the bearing circuits and reduce service life.
