introduction:ikoStandard for needle roller bearings IKONeedle roller bearings are roller bearings with cylindrical rollers,Relative to its diameter,The roller is thin and long。This roller is called a needle roller。Despite having a smaller cross-section,The bearing still has a high load bearing capacity,Needle roller bearings are fitted with long thin rollers(Roller diameterD≤5mm,L/D≥2.5,LIs the length of the roller),Thus the radial structure is compact,Its inner diameter and load capacity are the same as other types of bearings,Small outside diameter,Especially suitable for support structures with limited radial mounting size。The following is a small edition of Feng Ye to take you to understandikoStandard needle roller bearings!
