SKF NU 2248 MA/C3

1. Product Description

The SKF NU 2248 MA/C3 bearing is a cylindrical roller bearing, designed to support high radial loads. This type of bearing is particularly suitable for applications requiring resistance to high loads and high rotation speeds.

2. Materials and Construction

• Rings and Rollers: Made of high strength alloy steel, typically chrome steel (100Cr6), which offers a combination of hardness and toughness.
• Coatings: SKF bearings may include protective coatings against corrosion and wear, although the NU 2248 MA/C3 is generally without coatings.
• Seals: It is not equipped with seals, making it suitable for applications where protection against external contaminants is not necessary.

3. Dimensions and Weight

• Internal Diameter (d): 240 mm
• External Diameter (D): 440 mm
• Width (B): 72mm
• Weight: Approximately 25 kg

4. Mechanical Characteristics

• Radial Load Capacity: High, thanks to the arrangement of the cylindrical rollers which distribute the load evenly.
• Working Speed: Suitable for high speeds thanks to its design and high quality materials.
• Radial Clearance: C3, which indicates greater radial clearance than class C2 or C0 bearings, allowing for wider mounting tolerances and thermal expansion.
• Accuracy: Good, designed for industrial and precision applications.

5. Mathematical formulas

• Radial Load Capacity (C): The radial load capacity can be calculated using the formula C=FfC = \frac{F}{f} $C$ $=$ f F ​, FF $F$ is the applied load and ff $f$ is the factor of duration.
• Nominal Life (L10): The nominal life of the bearing is calculated with the formula L10=(CF)3L10 = \left( \frac{C}{F} \right)^3 $L$ $10$ $=$ $($ F C ​) 3 , where CC $C$ is the load capacity and FF $F$ is the applied load. The L10 rated life indicates the number of hours at which 90% of the bearings will reach or exceed the specified life under the defined load and speed conditions.

6. Sectors of Use

• Industry: Ideal for machine tools, transmissions and pumps, where great resistance to radial loads is required.
• Automotive: Used in high-performance vehicle components.
• Energy: Suitable for turbines and generators in the energy sector, thanks to its resistance and reliability.

7. Advantages of Purchasing in Stock

• Immediate Availability: Ensures the bearing is ready for immediate use, reducing machine downtime.
• Lower Cost: Purchasing from stock can offer more competitive unit prices thanks to bulk purchasing.
• Reduce Wait Time: Minimize wait times for replacement and maintenance, helping to keep operations running without interruption.
