Needle Roller Bearing (KOYO):
Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
Needle bearing characteristics and uses:
With thin and long needle bearing roller (roller length diameter of 3 to 10 times the diameter of generally not more than 5mm), so the radial structure is compact, its internal diameter and load capacity of the same with other types of bearings, minimum diameter, especially for radial bearing mounting dimensions restricted results. According to use different, and can be used without inner ring of the bearing or needle roller and cage assemblies, at this time to match the journal and the bearing surface and the shell holes, as bearing directly on the surface, the outer rolling surface, in order to ensure load capacity and operational performance and have the same ring bearings, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing ring.
Such bearings can only bear radial load
