Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep-groove ball bearings stand out for their versatility, their ability to operate at high speeds, and their low maintenance requirements.

Featuring silicon nitride balls, low-friction seals, a polyamide cage, and high-quality lubrication, this SKF rigid ball bearing ensures high performance and easy installation. Ideal for supporting radial and axial loads, it is perfect for highly demanding environments where reliability is paramount. Its hybrid design offers excellent protection against electrical damage while improving service life and wear resistance.

Features:
This SKF ball bearing is designed to meet the demands of high-performance applications. The steel rings, combined with silicon nitride (Si3N4) rolling elements, ensure effective electrical insulation and improved wear resistance. The glass-fiber-reinforced polyamide 6.6 cage reduces friction, providing increased speed capacity and extended service life. This bearing can handle heavy radial loads and moderate axial loads in both directions. Thanks to its increased clearance (C3), it better accommodates thermal expansion, making it an ideal choice for high-speed applications where heat dissipation is critical. Additionally, it is pre-lubricated during assembly with a high-performance polyurea-thickened grease and protected by two low-friction nitrile seals.

Maintenance:
Designed to minimize maintenance requirements, this SKF bearing features NBR seals that retain the lubricant while preventing the ingress of contaminants. To ensure optimal performance, it is recommended to regularly monitor operating temperature and vibrations. These periodic checks allow for early detection of any abnormalities and extend the product’s service life.

Sealing:
It is equipped with the new RSL seals developed by SKF. These seals have been optimized using finite element analysis, ensuring excellent protection against contaminants while reducing friction losses. These seals provide a durable seal, effectively retaining lubricant while preventing the ingress of moisture and other contaminants. This sealed design significantly improves the bearing’s service life, even in highly contaminated or corrosive environments. These low-friction seals can withstand operating temperatures ranging from -40 to +100 °C and up to +120 °C for short periods.

Brand information:
SKF, founded in 1907, is a global leader in the supply of bearings and industrial maintenance solutions. With a presence in more than 130 countries and an extensive distribution network, SKF is committed to providing innovative, high-quality products to improve the efficiency of industrial equipment.

Key Features:
- Protection against electrical damage thanks to silicon nitride components.
- New generation of sealed rubber seals for extended service life.
- Increased clearance (C3) for better performance at high speeds.
- Enhanced wear resistance and reduced risk of seizure with the polyamide cage.
- High-performance grease effective over a wide temperature range.
- Suitable for demanding and highly contaminated environments.

Applications:
The sealed, rigid silicon nitride ball bearing, with C3 radial clearance and a polyamide cage, is ideal for:
- Electric motors, thanks to its low friction and increased clearance, as well as its ability to block parasitic electrical currents.
- Pumps and compressors, as its polyamide cage provides better resistance to vibrations.
- High-speed applications, due to the light weight of silicon nitride and the C3 radial clearance.
- Humid or dusty environments, thanks to its seals that protect against contaminants.
