Industrial W210PPB6 Square Bore Sealed Insert Bearing

The W210PPB6 1-1/8" square-bore sealed insert bearing is built for heavy-duty shaft support in disc harrows and other soil-tillage equipment. It uses a spherical outer race insert bearing with a triple-lip sealed, non-relubricatable design that is pre-greased and sealed-for-life for press-fit mounting into agricultural disc gangs. Key dimensions include an outside diameter of approximately 3.543 in (90 mm), an inner ring width of about 1.438 in, and an outer ring width of about 1.188 in, with a 1-1/8 inch square bore. Made from high-carbon chromium bearing steel, it accommodates misalignment and withstands high shock loads in dusty, vibrating environments. Manufacturer options include Fafnir / Peer / OEM equivalents, and it is commonly applied in disc harrows, tillage machines, planters, and other heavy-duty agricultural implements where sealed, self-aligning bearings are required. Common replacements: Fafnir W210PPB6, Timken DS210TT6, Peer W210PPB6.
