SHAPE LOCATION TOLERANCE SHOULD BE TO CURRENT STANDARD;

The cylindrical roller bearing is composed of inner ring and roller guided by shoulder and with cage. The

cylindrical roller is generally differentiated in accordance with the different shoulders. The cylindrial roller bearings made by our company include Model N, NU, NJ, NUP, NF and Model NUP...N, NUPN...NR with snap ring.

This kind of bearings has a high rigidity and high load carrying capacity, generally only withstanding the

radial load. Except the full complement needle roller bearing, the bearings are equipped with high rigid cage correctly to guide the roller parallel to axis line.

The structure of cylindrical roller bearing is distinguished in accordance with the different shoulders. Model NU cylindrical roller bearing has the outer ring with two shoulders and one inner ring without shoulder. As for Model N cylindrical roller bearing, the inner ring has two shoulders and the outer ring has no shoulder. Model NU, N cylindrical roller bearings are running bearings. The inner ring and outer ring can be separated conveniently for mounting and dismounting. As for Model NJ cylindrical roller bearing, the outer ring has double shoulders and the inner ring has single shoulder. As for Model NF cylindrical roller bearing, the inner ring has double shoulder and the outer has single shoulder, they can withstand the single-directional axial force. Model NUP cylindrical roller bearing is used as fixing bearing, withstanding the alternate directional axial force. The outer ring of it has double shoulder and one baffle ring.

Model NUP...N, NUP...NR cylindrical roller bearings with snap ring,

The cylindrical roller bearing with the outer ring with a sop slot in the inner ring and single-shoulder and flat baffle ring in the inner ring is the modified type with Model NUP bearing adding a stop slot. It can simplify the axial fastening of bearing in housing bore. Because of through hole in outer housing, the axial size can be reduced.
