INA aligning needle roller bearings

As INA bearing distributor, Nodes bearings have INA aligning needle roller bearings in stock. On time deliveries, no minimums quantities, and combined sales experience of over 20 years in this field.

INA aligning needle roller bearings are units comprising 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.

INA aligning needle roller bearings are firmly seated in the housing bore. The bore can therefore be produced easily and economically.

INA aligning needle roller bearings with/without inner ring

INA bearings of type RPNA do not have an inner ring and are therefore particularly compact. However, they requirea raceway that is hardened and ground.

INA bearings of type PNA have an inner ring. They are used if the shaft cannot be configured as a rolling bearing raceway.

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.
