CR N 4011 Cylindrical Roller Bearing - 55x100x25mm - High Radial Load and Stiffness
The CR N 4011 is a robust single-row cylindrical roller bearing designed specifically for applications demanding very high radial load capacity and superior stiffness. Featuring the N-type configuration, this bearing has two integral flanges on the outer ring but no flanges on the inner ring. This design enables axial displacement of the shaft relative to the housing, accommodating thermal expansion without generating internal stress, making it ideal for non-locating bearing positions. Manufactured using high-grade, stabilized bearing steel, the precision-ground rollers and raceways minimize friction and heat generation, ensuring prolonged service life even under continuous operation and demanding shock loads. The standard configuration utilizes a durable pressed steel or reinforced polyamide cage, optimized for reliability across various operating temperatures.
Engineered for challenging industrial environments, the N 4011 is indispensable in heavy machinery sectors such as gearboxes, large pumps, rolling mills, and power generation equipment. Its separable components (the inner ring can be mounted separately from the roller and outer ring assembly) simplify installation, inspection, and maintenance procedures, significantly reducing downtime. By offering maximum geometric precision and enhanced running accuracy, the CR N 4011 provides unparalleled rotational stability and is a direct, reliable replacement for equivalent competitor models, guaranteeing sustained performance and reliability essential for critical machinery components. Select the N 4011 for optimized efficiency and reduced total cost of ownership in high-speed, high-load applications.
