Deep groove ball bearing SKF 6204-2RSLTN9/HC5C3W64, Outer diameter: 47 mm | Width: 14 mm | Inner diameter: 20 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, their ability to operate at high speeds, and their low maintenance requirements.

This SKF-brand deep groove ball bearing is designed to meet the needs of the most demanding industrial applications. It offers enhanced reliability and extended service life thanks to its unique hybrid design and rubber seal technology. Suitable for harsh operating environments, it is particularly effective at supporting radial and axial loads in both directions, while offering low rolling resistance, making it ideal for high rotational speeds.

Features:
This single-row ball bearing features an innovative hybrid design, combining steel rings and rolling elements made of silicon nitride (Si3N4), a highly hard and wear-resistant material. It is equipped with a glass-fiber-reinforced polyamide cage, offering both light weight and robustness. Its C3 internal radial clearance allows for high rotational speeds while reducing internal friction. Nitrile-butadiene rubber (NBR) lip seals provide excellent protection against contaminants while retaining the lubricant, ensuring long-lasting performance. This model is filled with Solid Oil, an oil-saturated polymer that occupies nearly all available space. This design ensures optimal performance, even in humid environments. The microporous structure of Solid Oil retains the oil through surface tension and slowly releases it upon contact with internal surfaces, providing continuous, low-intensity lubrication. This improves the bearing’s performance, making it an ideal choice for systems requiring efficient cooling.

Maintenance:
Maintenance of this deep-groove ball bearing is minimal thanks to its sealed design. It does not require frequent lubrication, as its Solid Oil lubrication system extends the product’s service life and ensures continuous performance. However, it is recommended to regularly check its operating condition—including temperature and vibration—to detect any signs of malfunction. In the event of extreme temperature or load conditions, periodic inspection is necessary to ensure maximum service life.

Sealing:
This bearing is equipped with nitrile-butadiene rubber (NBR) lip seals on both sides. These seals provide effective protection against water, dust, and other external contaminants. They help keep the lubricant inside the bearing while preventing the intrusion of harmful particles. This ensures enhanced protection, even in dusty or humid environments. Solid Oil reinforces the sealing provided by the rubber seals. Solid Oil not only limits the intrusion of particles but also enhances the effectiveness of the integrated seals, increasing their durability and ensuring reliable, long-lasting performance, even under demanding conditions.
