Bearing NU 212 ECML/C3B20 SKF
The NU 212 ECML/C3B20 SKF is a high-quality cylindrical roller bearing designed to meet the demands of various industrial applications. Manufactured by SKF, a globally recognized leader in bearing technology, this bearing ensures reliable performance, durability, and precision under challenging operating conditions.
This particular model, NU 212 ECML/C3B20, belongs to the NU series of cylindrical roller bearings which are known for their ability to accommodate heavy radial loads and high speeds. The ECML designation indicates an optimized internal design for enhanced load capacity and extended service life, while the C3 clearance provides additional internal clearance for thermal expansion and shaft deflection, making it suitable for applications with high operating temperatures or shaft misalignment.
Key features of the NU 212 ECML/C3B20 SKF include:
- Design: Single row cylindrical roller bearing with a two-piece inner ring that allows for axial displacement of the shaft relative to the housing.
- Internal Clearance: C3 clearance providing greater radial internal clearance than standard bearings, improving performance under higher temperatures and speeds.
- Material: High-grade bearing steel ensuring excellent wear resistance and fatigue life.
- Separation Capability: The design allows easy mounting and dismounting, simplifying maintenance and replacement.
- Optimal Lubrication: Designed to operate effectively with proper lubrication for reduced friction and extended bearing life.
Dimensions for the NU 212 bearing series are standardized, and the NU 212 ECML/C3B20 SKF typically features the following measurements:
- Inner Diameter (d): 60 mm
- Outer Diameter (D): 110 mm
- Width (B): 22 mm
These dimensions make the NU 212 ECML/C3B20 SKF suitable for use in electric motors, gearboxes, pumps, and other machinery where robust radial load carrying capacity and precise rotational accuracy are required.
Choosing the NU 212 ECML/C3B20 SKF ensures that your equipment operates smoothly, reduces downtime, and benefits from SKF's extensive engineering expertise and quality assurance. Whether you are replacing worn bearings or designing new systems, this bearing provides a reliable solution backed by one of the most trusted names in the industry.
