Full-Complement Bearings
These utilize filling notches or angular contact design to maximize ball quantity, which eliminates the need for a retainer/cage. This design increases the load capacity.

Custom & Specialty
These bearings could have “modified attributes”, including non-standard bores, outside diameters, widths, and internal geometry.

Miniature-Inch Flanged Series
Our offerings with Outer Ring Flanges. The flange assists in positioning and mounting of the bearing.
