FAG 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.
FAG self-aligning ball bearings can support axial forces in both directions as well as radial forces.
FAG self-aligning ball bearings with cylindrical or 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.
FAG self-aligning ball bearings with adapter sleeve
Self aligning ball bearings with a tapered bore are also available with an adapter sleeve, locknut and tab washer. Adapter sleeves must be ordered in addition to the bearing.
FAG self-aligning ball bearings with extended inner ring
FAG bearings of series 112 have an extended inner ring, a locating slot on one side of the inner ring and are located by means of dowel pins.
These bearings are intended for simple bearing arrangements with conventional shafts. Due to the bearing bore tolerance (J7), they are very easy to fit.
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.
Sealed bearings are greased with a high quality grease and are maintenance-free.
Compensation of angular misalignments
Under normal operating conditions and with a rotating inner ring, self-aligning ball bearings can swivel approx. 4° about their central position; sealed bearings can swivel by max. 1,5°. As a result, they permit skewing between the inner and outer ring and can thus compensate misalignments, shaft deflections and housing deformations.
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.
FAG self-aligning ball bearings cages
Self-aligning ball bearings with cages made from glass fibre reinforced polyamide 66 have the suffix TVH.
Ball-guided solid brass cages are indicated by the suffix M.
