The various structure of cylindrical roller bearing is what to distinguish

Cylindrical roller bearing is a bearing inner ring and outer ring with guard guide roller with complete unit composed of cage. Cylindrical roller bearing often to guard to distinguish different, this company produces the cylindrical roller bearing with N, NU, NJ, NUP, NF type and NUP with a snap ring. 。 。 N、NU. 。 。 NR type cylindrical roller bearing. This kind of bearing with high stiffness, - As only used to bear radial load, large load capacity. In addition to the full roller bearings, adopt high rigid retainer, correctly guide roller is parallel to the axis. Cylindrical roller bearing a variety of structure is different to distinguish guard. NU type cylindrical roller bearing, the outer ring has two guard and an inner ring without a guard. N type cylindrical roller bearing, which has two guard, outer ring without guard. NU, N type cylindrical roller bearings are floating bearing, inside and outside the circle can be separated, convenient to install and remove. Double guard NJ type bearing outer ring, inner ring with single guard; NF type bearing double guard is the inner ring, outer ring on a single guard, they can withstand a one-way axial force. NUP type fixed bearing, cylindrical roller bearing as can withstand alternating direction of axial force, this kind of bearing outer ring with double guard and a retainer. With a snap ring cylindrical roller bearing NUP. 。 。 N、NP。 。 。 NR. Outer ring has a locking groove, inner ring have single guard with flat cylindrical roller bearing collar, this type of bearings is NUP on the outer ring with a snap ring groove variant, can be simplified bearing in casing hole axial fastening, the shell hole hole can make it, to narrow the axial dimension of the parts.
