Aligning needle roller bearings are X-life bearings. These bearings have optimised raceway surfaces. This gives higher load carrying capacity and longer rating life.
Bearings without inner ring have particularly compact radial dimensions. However, they require a shaft raceway that is hardened and ground.
Compensation of Misalignments : Due to the Spherical Outer Ring and the concave support ring, aligning bearings can compensate static misalignments between the shaft and housing of up to 3°.
Sealing : Aligning needle roller bearings are not sealed.
Lubrication : The open bearings can be lubricated with oil or grease.
Operating temperature : The range of possible operating temperatures is from –20 °C to +100 °C,
restricted by the plastic support rings.
Cages : The cages are made from sheet steel.
