Self Aligned Ball Bearings

Self-aligning ball bearings are double-row, self-retaining units consisting of outer rings with a concave raceway, inner rings with a cylindrical or tapered bore, and ball and cage assemblies. These bearings are available in both open and sealed designs.

They can support axial forces in both directions, as well as radial forces, and are offered with either a cylindrical or tapered bore.

Self-aligning ball bearings are highly effective in compensating for misalignments. The maximum permissible misalignment from their centre axis depends on the bearing design, series, and actual operating conditions.

Open self-aligning ball bearings with brass cages can be used at operating temperatures ranging from -30°C to +150°C, while bearings with cages made from glass fibre-reinforced polyamide are suitable for operating temperatures up to +120°C.

Sealed self-aligning ball bearings are suitable for operating temperatures from -30°C to +100°C, depending on the grease used and the type of seal material.
