1. Suffix designation "X":columned surface. for example,NATR 40X;
2. Usually when the columned outer ring is mounted into the housing in normal tolerance, Cr and Cor is working; when the outer ring is used as track roller,Cw and Cow is working;
3. Limited speed for oil: about 30% higher than the one of grease;
