These single or double row units comprise machined outer rings without ribs, needle roller and cage assemblies and removable inner rings. Since the bearings are not self-retaining, the outer ring, needle roller and cage assembly and inner ring can be fitted independently of each other.
Needle roller bearings without ribs are X-life bearings. In this design, the raceway surfaces are optimised. 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.
The needle roller and cage assembly can be fitted either together with the outer ring or with the shaft. It can also be subsequently slid between the outer ring and shaft.
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.
Bearings with plastic cage can be used at operating temperatures from –20 °C to +120 °C.
The cages are made from sheet steel or plastic. Bearings with a plastic cage have the suffix TV.
