This 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. The applications of single row cylindrical roller bearings including: gearboxes, agricultural machinery, pumps, compressors, and electric motors. The NUP244-EM is a single row cylindrical bearing with NUP design. The outer ring has two rigid ribs, while the inner ring has one rigid and one loose rib. As a result, this bearing can take radial forces as well as axial forces in both directions. NUP bearings are used as locating bearings. Locating bearings locate a shaft axially in both directions. The NUP244-EM cage material: brass. Special strength and durability under extreme conditions such as shock loads and vibrations, high acceleration forces and lack of lubrication.
