SKF W211-PPB4 Disc Harrow Bearing For Agricultural Equipment

SKF W211-PPB4 Disc Harrow Bearing is a heavy-duty, round-bore bearing designed for agricultural disc harrow gangs. This non-relubricatable unit features a spherical outer race and triple-lip seals to keep out dirt and moisture in demanding field conditions. It accepts a 2.188-inch (55.56 mm) bore and has an outer diameter of 3.937 inches (100.00 mm), with a bearing width of 2.1875 inches (55.56 mm) for robust support in disc-harrow hubs. Marketed variants include UBS W211PPB4 by some suppliers, reflecting its role as a standard replacement part across several agricultural brands. The spherical outer race helps tolerate minor misalignment in disc-harrow hubs, while the sealed, non-relubricatable design minimizes maintenance in harsh soils and residues. This bearing is commonly used in disc gangs, gauge wheels, and other tillage attachments that rely on reliable rotation and load handling in farming operations.
