Nippon Thompson Co., Ltd. is a bearing manufacturer that launched the technical development of needle roller bearings for the first time in Japan and is proud of the high quality level and abundant varieties of its products. Needle roller bearings are bearings for rotary motion that incorporate needleshaped thin rollers instead of ordinary bearing balls or rollers. Compared with other rolling bearings, they are small-sized and lightweight but have a large load capacity. They are widely used with high reliability in the fields of automobiles, industrial machinery, OA equipment, etc. as resource-saving type bearings that make the whole machine compact.

Characteristics of Needle Roller Bearings Characteristics of Needle Roller Bearings Bearings can be classified classifiedmain two main types, namely rolling and sliding bearings. bearings. Rolling bearings Bearings can be into two into types, namely rolling bearings bearings and sliding Rolling bearings can be subdivided further into ball bearings and roller and roller accordingaccording to the rolling elements. can be subdivided further into ball bearings bearings bearings to the rolling elements.

Basic Dynamic Load Rating Rolling bearings will suffer damage due to various causes during service. Damage such as abnormal wear, seizure, and cracks is caused by improper use, including incorrect mounting, lack of oil, dust intrusion and so on, and can be avoided by remedying these causes. However, bearings will eventually be dam- aged due to fatigue-flaking even if used properly. When a bearing rotates under load, the raceways and the rolling elements are subjected to repeated stress- es concentrated on the part close to the surface. Fatigue, therefore, occurs in the surface layer, pro-...
