Features
Self-aligning ball bearings are double row, self-retaining units comprising outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies.The bearings are available in open and sealed designs.
Radial and axial load capacity
Self-aligning ball bearings can support axial forces in both directions as well as radial forces.
With cylindrical/tapered bore
Bearings of series 12, 13, 22 and 23 are available with a cylindrical or tapered bore.Bearings with a tapered bore have a bore taper of 1:12 and the suffix K.
Sealing/lubrication
Self-aligning ball bearings of series 12, 13, 22 and 23 are also available in sealed designs. Sealed bearings have contact seals on both sides and the suffix 2RS.They are greased with a high quality grease and are maintenance-free.
Operating temperature
Open bearings with brass cages can be used at operating temperatures from –30 °C to +150 °C.
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, restricted by the grease and seal material.
