The SKF NU 2222 ECML/C3 is a radial cylindrical roller bearing ideal for handling heavy radial loads and high-speed environments. This specific model, part of the NU series, features a flangeless inner ring, allowing the bearing to accommodate axial movement, making it ideal for applications with thermal expansion or poor alignment.

Materials and Construction

The SKF NU 2222 ECML/C3 is made of high-quality steel and machined with extreme precision. The rollers and rings are hardened to ensure long life and optimum wear resistance. The solid brass cages (ECML) are durable and designed to ensure even load distribution across the rollers, thus improving overall service life.

Dimensions and Weight

This model has the following dimensions:

• External diameter : 200 mm
• Internal diameter : 110 mm
• Width : 38 mm
• Weight : about 5.9 kg

Mechanical Characteristics

The main mechanical features of the SKF NU 2222 ECML/C3 include:

• Dynamic load capacity : 430 kN
• Static load capacity : 430 kN
• Limiting speed : up to 3200 rpm under adequate lubrication conditions. The increased internal clearance (C3) allows the bearing to operate at high temperatures without thermal expansion problems.

Sectors of Use

This bearing is mainly used in industries such as:

• Industrial transmissions
• Mining
• Heavy machinery
• Steel production
• Chemical processing plants

Assembly and Maintenance

Mounting requires care to avoid overloading or misalignment. Using appropriate mounting tools, such as SKF pullers, facilitates installation without damaging the bearing. Proper lubrication is essential to ensure maximum performance and extended operating life. The oil or grease used must be high-quality and suitable for the specific application.
