Heavy duty needle roller bearing is composed of one or two rings and needle roller group with cage. According to different applications, it can be divided into bearings with or without inner rings. Therefore, the solid ring needle roller bearing can meet the requirements of light weight, small space occupation and high power transmission. The solid ring needle roller bearing has smaller volume and higher bearing capacity. Structure type outer ring double rib (or double lock ring) with cage needle roller bearing Na, NAV, NKI type can be respectively installed with inner ring and outer ring (with lock ring, full set of needle roller and cage), with high authorized speed, which can be divided into single row and double row. If the shaft cannot be used as a raceway, i.e. if it is not possible or economical to grind the shaft for hardening, this type of needle roller bearing with inner ring can be used
