Flanged ball bearing units
SKF flanged ball bearing units consist of an insert bearing mounted in a housing, which can be bolted to a machine wall or frame. The SKF assortment includes units compliant with ISO standards, North American standards, or Japanese Industrial Standards (JIS). Within the SKF assortment, you can find units for nearly all requirements regarding bolt patterns or locking on the shaft.
In addition, SKF Food Line ball bearing units provide hygienic and high-performance bearing unit solutions for the most demanding food and beverage environments.

Y-bearing units can accommodate moderate initial misalignment, but normally do not permit
axial displacement. They are ready-to-mount, ready-to-use units († fig. 1) and available as:
• - Y-bearing - plummer - block - units
• - Flanged - Y-bearing - units -
• - - Y-bearing - take-up - units The housings are available in:
• - composite - material - († fig. 2)
• - grey - cast - iron - († fig. 3)
• - - sheet - steel - († fig. 4)
SKF Y-bearing units provide designers with considerable freedom of choice so that compromises can be avoided. Numerous standard series Y-bearing units are available († tables on pages 20 to 23). The tables list Y-bearings and Y-bearing housings and their possible combin ations to units. For information about more specialized Y-bearing units, refer to the sections, SKF ConCentra ball bearings and units and SKF Food Line Y-bearing units starting on page 247.
