The bearings comprise drawn outer cups, plastic support rings with a concave inner profile, outer rings with a spherical outside surface, needle roller and cage assemblies and removable inner rings.
Aligning needle roller bearings are X-life bearings. These bearings have optimised raceway surfaces. This gives higher load carrying capacity and longer rating life.
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°.
Needle roller bearings with inner ring : Bearings with an inner ring are used if the shaft is not configured as a rolling bearing raceway.
Displacement of the inner ring : The standard inner ring allows axial displacement within the values “s” stated in the dimension tables. Where larger displacements occur, the standard ring can be replaced by a wider inner ring IR. Inner rings: see link.
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.
