High Radial Load Capacity: The internal geometry is designed to maximize load distribution, thereby extending service life under demanding operating conditions.
NJ-Type Configuration: Features a design with two flanges on the outer ring and one flange on the inner ring, facilitating axial positioning and enabling effective resistance against unidirectional axial loads.
ECM Cage: Constructed from glass fiber-reinforced Polyamide 66; compared to standard brass or steel cages, it offers lower noise levels, reduced heat generation, and superior lubricant flow characteristics.
High-Speed Capability: The optimized design of the rollers and raceways effectively minimizes centrifugal forces, allowing the bearing to maintain efficient and stable operation even at high rotational speeds.
Separable Components: The inner ring is detachable, significantly simplifying the installation, maintenance, and inspection processes for complex industrial assemblies.
High Dimensional Precision: Manufactured to rigorous tolerance standards, ensuring perfect interchangeability and consistently superior performance within modular systems.
