Double Row Precision Cylindrical Roller Bearing NN3013KW33/P5

When high accuracy and heavy radial loads meet in high-speed spindles, super precision cylindrical roller bearings deliver the performance you need.

• New materials and a refined design take machine tool performance to the next level.

• Optimized for higher speeds with reduced heat generation.

• Longer service life through reliable grease lubrication.

• Stable rotation at high speeds, supported by a high-rigidity PPS resin cage that controls deformation under centrifugal force.

1. Precision Machine Tool Industry
These bearings serve as core spindle supporting components for mainstream precision machining equipment, including CNC lathes, vertical and horizontal machining centers, milling machines and high-speed grinding spindles. Their superior rigidity effectively resists cutting vibration and spindle deflection during heavy-duty machining, while the low-heat and high-speed structural design ensures stable long-cycle operation. They maintain consistent machining accuracy during both rough cutting and ultra-precision finishing, greatly improving the processing efficiency and finished product quality of intelligent machine tools.

2. Automotive Precision Manufacturing
Widely used in high-precision spindle equipment and automated production lines for automotive core component manufacturing. They are specially applied to the machining and processing of engine parts, transmission components and chassis structural parts. With reliable heavy-load resistance and high rotational stability, the bearings adapt to the high-frequency and continuous working state of automotive assembly and precision machining lines, ensuring uniform processing precision and stable mass production consistency for automotive parts.

3. Aerospace High-End Machining Field
Ideal for high-precision machining centers dedicated to aerospace core component production. They support the precision processing of turbine blades, aircraft structural parts and other critical aerospace components that require ultra-high precision and extreme reliability. The bearings' anti-deformation, low-vibration and long-life performance meets the strict standards of aerospace manufacturing, effectively avoiding precision errors caused by spindle instability and guaranteeing the safety and qualification of key aviation parts.

4. High-Precision Medical Equipment Industry
Applicable to high-speed dental tools, surgical precision instruments and professional medical device manufacturing machinery. Relying on stable high-speed operation, low noise and high precision advantages, the bearings ensure the smooth and accurate operation of miniature high-speed medical equipment. Meanwhile, their durable and low-maintenance characteristics meet the long-term stable operation requirements of medical production equipment, complying with the high cleanliness and high reliability standards of the medical industry.

5. General High-End Industrial Machinery
Suitable for various high-speed industrial equipment that requires stable radial load capacity and continuous operation, including high-speed industrial pumps, precision compressors and other key mechanical equipment. The double-row roller structure provides excellent radial load-bearing capacity, while the optimized lubrication and low-friction design reduces equipment heat generation and wear. It effectively improves the operational stability and service cycle of general industrial high-speed rotating equipment, reducing overall industrial operation and maintenance costs.
