Characteristics of Needle Roller BearingsBearings can be classified into two main types, namely rolling bearings and sliding bearings. Rolling bearings can be subdivided further into ball bearings and roller bearings according to the rolling elements.IKO Needle Roller Bearings are high-precision rolling bearings with a low sectional height, incorporating needle rollers as the rolling element. They have the following features. Merits of Rolling Bearings Merits of Needle Roller BearingsCompared with sliding bearings, rolling bearings Compared with other rolling bearings, IKO Needle have the following merits:Roller Bearings have the following advantages: Static and kinetic friction is low. With a low sectional height, they can withstand heavy loads.the between difference Since and kinetic friction is small and the frictional coefficient is also can be made more compact and lightweight, saving machine costs and power consumption.small, drive units or machines friction static they have a low rolling bearings and compared Since with other can withstand heavy loads, machines can be made more compact and lightweight, thus saving costs.sectional height yet Stable accuracy can be maintained for long periods. Rotating torque is small, improving mechanical efficiency.Owing less maintained for long periods.wear, to stable accuracy can be Since the rotating radius is small, the rotating torque is also small under frictional conditions, the same thus improving mechanical efficiency. Machine reliability is improved. Inertia is minimized.the bearing Since rolling fatigue, machine reliability is improved.life can be estimated based on Since the bearing volume and weight are small, the moment of inertia of the bearing is minimized when it is put in motion. Lubrication is simplified. Most suited to oscillating motions.rolling elements Many small spacing pitch, and this configuration is most suited to oscillating motions.arranged are at a Since grease lubrication is sufficient in most cases, lubrication can be simplified for easy maintenance.A3
