I AM SELLING SKF NU 2248 MA/C3 BEARING STILL IN THE BOX

7000 euros

The SKF NU 2248 MA/C3 bearing is a monorow cylindrical roller bearing designed for applications requiring high performance and resistance to high radial forces. This bearing features a solid inner and outer ring, with cylindrical rollers arranged in a cage that prevents contact between the rollers, thus allowing higher speeds than cageless cylindrical roller bearings. The MA design, with a brass cage, is outer ring-centered for maximum durability and reliability.

Main technical data:

• Internal diameter (d): 240 mm
• External diameter (D): 440 mm
• Width (B): 120 mm
• Weight: 85.4 kg
• Cage type: Brass cage (outer ring centered)
• Closure: Without seal
• Internal clearance: C3 (radial clearance greater than normal)
• Accuracy: Standard
• Thermal stabilization: Not thermally stabilized (max 120°C)​

Features and Benefits:

The SKF NU 2248 MA/C3 bearing is designed to accommodate high radial forces and is particularly wear-resistant. Its brass cage ensures smoother operation, reducing friction and increasing service life. As a monorow bearing, it is ideal for applications that require the support of radial loads but do not absorb axial forces in either direction, unless combined with HJ support rings. Thanks to its construction, it can be easily disassembled, facilitating maintenance and installation.

Sectors of use:

This bearing is commonly used in high-speed industrial applications such as:

• Speed ​​reducers
• Agricultural machinery
• Pumps
• Compressors
• Electric motors​
  .

How to assemble it:

This bearing must be installed carefully, following the specific instructions to avoid damaging the rings and rollers. It is essential that the bearing is correctly positioned in the housing, without any deformation, to ensure optimal operation. Furthermore, since it is not sealed, it is important to ensure that the operating environment is not excessively dusty or contaminated by other impurities.

Maintenance:

Maintenance of an SKF NU 2248 MA/C3 bearing includes regularly checking the internal clearance and the condition of the brass cage. Since the bearing is unsealed, it is essential to ensure the operating environment is free of dust or other abrasive particles. It is advisable to periodically check the lubrication condition and replace the lubricant when necessary to prevent premature wear.

Why buy it used:

Buying a used SKF NU 2248 MA/C3 bearing in good condition is a smart choice for those looking to keep costs low without compromising quality and reliability. SKF is renowned for producing high-quality bearings, and buying a used bearing allows you to get a high-performance product at a more affordable price, without having to invest in a full-price new bearing.

How to size it:

To correctly size the bearing, it is necessary to calculate the radial forces to which it will be subjected during its operating cycle. The main variables to consider include:

1. Maximum radial load : Determined by machine and application.
2. Angular velocity : which must fall within the operating speed limits of the bearing (in this case, up to high speeds, but still within the design limits).
3. Operating temperature : which must not exceed 120°C.
