Needle roller bearings (needle bearing) is a
cylindrical roller with roller bearings, relative to its diameter,
roller both thin and long. This is called needle roller. Despite
having a smaller cross-section, has a higher load bearing capacity,
thin and long needle bearing mounted roller (roller diameter D≤5mm,
L / D≥2.5, L is the length of the roller), so radial structure is
compact, its diameter size and load capacity with other types of
bearings, minimum diameter, especially for radial bearing mounting
dimensions restricted results.
Depending on different
occasions, can be used without an inner ring of the bearing or
needle roller and cage assemblies, then the journal surface and the
surface of the bearing shell holes match directly as the bearing,
the outer rolling surface, to ensure the load capacity and
operational performance there are rings with the same bearing,
shaft or housing bore raceway surface hardness, machining accuracy
and surface quality should be similar bearing ring raceway. Such
bearings can only bear radial load.
