Nk20 is high quality needle roller bearing

Needle roller bearings nk20 are bearings with cylindrical rollers of less than a length in diameter.The end of the roller is shrunk slightly to improve the line contact between the roller and the raceway.This prevents peak stress at both ends of the needle roller, thus prolonging the life of the nk20 bearing.

Nk20 bearing is a bearing with a cylindrical roller, relative to its diameter, the roller is thin and long.This roller is called a needle roller.Although has a small cross-section, bearing still has high load capacity, nk20 bearing with fine and long roller for the roller length, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.
Needle roller bearing nk20 is equipped with a thin and long roller (roller diameter D≤5mm, L/D≥2.5, L is the roller length), so the radial structure is compact. Its inner diameter size and load capacity are the same as other types of bearings, and the outer diameter is the smallest.

Nk20 is especially suitable for bearing results where the radial installation size is limited.According to the use of different occasions, can be used without inner ring of the nk20 bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway.The bearing can only withstand radial loads.
