Cylindrical roller bearing is a type of rolling bearing that uses cylindrical rollers as rolling elements and is mainly used to withstand radial loads. Some models can withstand bidirectional axial loads structural characteristics Adopting a separable design of inner and outer rings for easy installation and disassembly Rollers and raceways are in line contact or modified line contact, with high radial load-bearing capacity According to the edge structure, it can be divided into NU (no edge), NJ (inner ring single edge), NUP (inner ring double edge) and other types Core strengths Applicable scenarios: Suitable for large and medium-sized electric motors, machine tool spindles, internal combustion engines, and other scenarios, capable of withstanding heavy loads and impact loads High speed performance: low friction coefficient, maximum speed close to deep groove ball bearings Axial adaptability: NU and N-type bearings allow for bidirectional axial displacement and are suitable as free end supports Installation requirements It is necessary to strictly control the machining accuracy of the shaft and seat hole to avoid stress concentration caused by the deviation of the outer ring axis
