cylindrical roller bearing with cage has good rigidity and can bear high radial load, and because of the cage, this kind of bearing is more suitable for high-speed situation compared with full design bearing. The bearing with suffix e has higher optimized bearing capacity, so it is suitable for higher load conditions.

one ring of this kind of bearing can be separated for easy installation and disassembly. The inner and outer rings can be tightly matched.

single row cylindrical roller bearing with cage can be used as non positioning, semi positioning and positioning bearing.

we can provide a variety of sizes of X-life grade bearings. These bearings are identified in the dimension table.

compared with non X-life bearings, the raceways of X-life bearings have smaller surface roughness Ra and higher geometric accuracy. Therefore, the X-life bearing of the same size has higher bearing capacity and longer life. In some applications, this means smaller bearings can be used.

floating bearing

n and Nu cylindrical roller bearings are floating bearings and can only bear radial force.

Nu type bearing outer ring with two flange, inner ring without flange. The inner ring of n type bearing has two stops, and the outer ring has no stops.

semi positioning bearing

NJ cylindrical roller bearing is semi positioning bearing. Half locating bearing can not only bear high radial load, but also bear unidirectional axial load, so it can locate the shaft in one direction. In the other direction, it can be used as floating bearing. This type of bearing has two stops on the outer ring and one stop on the inner ring.

Nu type floating bearing can be combined with a L type inclined retaining ring HJ to form a half locating bearing unit. However, it is not allowed to use two L inclined retaining rings at the same time ( there is a risk of jamming ) .

the relative axial displacement of the inner and outer rings in one direction is' s ', and the specific values are shown in the size table.

NUP and L inclined retaining ring HJ are positioning bearings.

positioning bearing can not only bear radial force, but also bear bidirectional axial force, so it can realize bidirectional axial positioning of shaft.

NUP the outer ring of cylindrical roller bearing type ' > has two stops, one side of the inner ring has a rigid stop, the other side has a flat retaining ring.

NJ type bearing can be combined with a L type inclined retaining ring HJ to form a positioning bearing unit. The outer ring of this bearing unit has two stops, and the inner ring has one stop, L inclined retaining ring is installed on the side of the inner ring without stop. For the parameters of NJ type bearing, L type inclined retaining ring HJ see the dimension table. Bearings and inclined retaining rings of type L need to be ordered separately.
