Deep groove ball bearing SKF 6313-2RS1/HC5C3WT, Outer diameter: 140 mm | Width: 33 mm | Inner diameter: 65 mm

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, ability to operate at high speeds, and low maintenance requirements.

This SKF rigid ball bearing is designed to withstand radial and axial loads in both directions. Featuring silicon nitride balls, it offers excellent protection against electrical currents, thereby extending the equipment’s service life. This product also features rubber seals that ensure maximum sealing, making this bearing particularly suitable for harsh environments with high levels of contamination.

Features:
Designed to deliver reliable and efficient performance under a variety of conditions, the silicon nitride balls in this ball bearing ensure protection against damage caused by electrical currents, while improving service life and wear resistance. The increased internal clearance (C3) reduces internal friction, which is ideal for achieving high speeds while limiting heat generated during operation. The sealed design with rubber seals provides excellent protection against contaminants, thereby improving the bearing’s overall reliability and its ability to operate in harsh environments. Furthermore, compared to bearings of the same size equipped with steel balls, silicon nitride elements offer better performance, extended service life, higher rotational speed, better wear resistance, and increased rigidity. This bearing is pre-lubricated with a special grease thickened with polyurea that is effective over a wide temperature range (from -40 °C to +160 °C).

Maintenance:
This SKF deep groove ball bearing, equipped with sealed seals, requires very little maintenance. The integrated seals effectively retain the lubricant, virtually eliminating the need for relubrication. However, it is recommended to regularly monitor temperature and vibrations to detect any signs of malfunction early on. The increased clearance (C3) helps reduce internal stresses, resulting in simplified maintenance and a long service life.

Sealing:
This bearing is sealed by rubber seals that effectively prevent the ingress of contaminants such as dust, moisture, and impurities. This design extends the bearing’s service life by preserving the internal lubricant and reducing the need for maintenance. The rubber seals provide long-lasting protection even in corrosive environments, ensuring stable performance over the long term.

Key Features:
- Effective protection against electrical currents thanks to silicon nitride balls
- Rubber seals providing superior protection against contaminants
- Increased clearance (C3) to reduce internal friction for better high-speed performance
- Reduced risk of seizure and false Brinell effect.
- Low sensitivity to temperature variations.
- Grease effective over a wide temperature range.

Applications:
This rigid ceramic ball bearing is particularly well-suited for applications requiring protection against electrical leakage. It is used in high-power electric motors, generators (primarily renewable energy), railway running gear (exposed to intense electromagnetic fields), and in applications in environments sensitive to electrical interference (medical imaging, the electronics industry, etc.). Its sealing and high-performance lubrication make it suitable for use in heavily contaminated environments without significant risk of corrosion.
