Cylindrical roller bearings are rolling-element bearings, they feature cylindrical rollers in linear contact with raceways, providing high load capacity and rigidity. Key characteristics include: high radial load capacity, separable design and low friction. Variants: Single-row (NU, NJ, NUP types), double-row, and full-complement designs for different load and space requirements. Common applications include wind turbines, machine tools, and automotive transmissions.
HECB is a prominent cylindrical roller bearings supplier/factory/stockist in China, recognized for its commitment to quality and innovation.The company specializes in manufacturing a diverse range of cylindrical roller bearings, Needle Roller Bearing, Track Roller Bearing, Tapered Roller Bearing, Deep Groove Ball Bearing and Spherical Plain Bearing designed to meet the needs of various industries, including heavy machinery, automotive, and industrial equipment.
Types of Cylindrical Roller Bearings
Single Row Bearings:
NU/N/NJ/NUP/NF Types: NU and N allow axial displacement, suitable as non-locating bearings. NJ handle unidirectional axial loads. NUP combines flanges and a loose ring for bidirectional axial positioning.
Double Row Bearings (NN/NNU): Feature higher radial load capacity with crossed roller arrangements. NNU and NN accommodate axial displacement.
Four Row Bearings: Designed for heavy duty applications like rolling mills, offering extreme radial stiffness.
Full Complement Bearings: Lack cages to maximize roller count for higher load capacity but lower speed tolerance.
Thrust Variants: Handle axial loads in specific configurations.
Special Types: Include sealed bearings (contaminant resistance), RN/RNU , and E-type.
