Single-row deep groove ball bearings are the most common type of rolling bearing. The raceway grooves in the inner and outer rings form a circular arc with a radius slightly larger than that of the balls.
In addition to open varieties, these bearings may have steel shields or come pre-lubricated with grease maintained by rubber seals install... View More

Filling slots in the inner and outer rings allow maximum ball bearings to contain a larger number of balls than normal deep groove ball bearings; however, the slots make them unsuitable for applications with high axial loads.
BL2 and BL3 types have boundary dimensions equal to those of Series 62 and 63 single-row deep groove ball bearings re... View More

The inner ring groove of magneto bearings is slightly shallower than that of deep groove bearings and the outer ring bore diameter on the side without a shoulder is cylindrical from the bottom. The outer ring may be separated, allowing easier mounting.
In general, two of these bearings are used together in a paired mounting (sometimes called... View More

Small, miniature, and instrument precision bearings broadly come in deep groove and angular contact varieties. Deep-groove types may have a flanged outer ring, special inner ring width, thin-walled cross-sections, or a special shape for synchros. These bearings can come open, sealed, or shielded.
