Cylindrical Roller Bearing Single Row With Removable Outer Ring N310E N320E
Cylindrical roller bearing, with cage, single row, non-locating bearing, 0 ribs on outer ring, 2 rib on inner ring, type N3
A single-row cylindrical roller bearing consists of a solid inner and outer ring with cylindrical rollers in a cage. This cage prevents contact between the cylinder rollers, so this bearing type can support higher speeds than full-complement cylinder roller bearings. Also, single-row cylindrical roller bearings with cages are very rigid and they can take high radial forces. As the inner and outer rings of these bearings can be easily disassembled, they are very easy to install.
Applications of single-row cylindrical roller bearings include gearboxes, agricultural machinery, pumps, compressors, and electric motors.
