Characteristics Of Needle Roller Bearings

- Nov 14, 2017 -

Needle roller bearings are fitted with thin and long rollers (roller diameters d≤5mm,l/d≥2.5,l to roller lengths), so the radial structure is compact, its inner diameter and load capacity are at the same time as other types of bearings, the outer diameter is the smallest, especially suitable for the radial mounting dimensions limited support results.

Depending on the use of the situation, you can choose the bearing or needle roller and cage assembly without inner ring, at this time, the shaft neck surface and the outer surface of the casing hole are directly used as the inner and outer rolling surface of the bearing, in order to ensure the load capacity and the running performance is the same as that of the ring bearing, the hardness of the raceway surface of the shaft or casing hole, The machining accuracy and surface quality should be similar to the raceway of bearing rings. The bearings are only capable of withstanding radial loads.
