The inner diameter of the Self-Aligning Double Row Ball Bearings is cylindrical or conical. The conical inner bore has a taper of 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.Bearings Direct's supply of self aligning ball bearings includes self-aligning double row ball bearings. These range from light to medium duty. Our light duty bearings are offered with or without seals.

The raceways in these bearings are positioned off-center to handle angular (combined radial and thrust) loads.. Double-row bearings handle thrust loads in both directions.. Open bearings dissipate heat more efficiently than shielded and sealed bearings.. Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
