INQUIRY

After many years’ development and research, NSK needle roller bearings have several series and are made from various material of steel. According to the material of outer ring, NSK needle bearing can be divided into drawn cup type and machined ring type, according to whether with inner ring or without inner rings, they can be divided into with inner ring bearing and no inner ring bearing. RNA6907 is needle roller bearing machined outer ring and without inner ring.
