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.
