Mélyhornyú golyóscsapágyak SKF 309 NR, Külső átmérő: 100 mm | Szélesség: 25 mm | Belső átmérő: 45 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 deep groove ball bearing offers enhanced strength and performance for demanding applications. With its fill grooves and sheet steel cage, this bearing is ideally suited for applications requiring a very high radial load capacity. Its integrated stop ring in the outer ring ensures good axial stability.

Features:
This SKF single-row deep groove ball bearing features an integrated stop ring in the outer ring, which ensures secure axial retention and minimizes the risk of misalignment. The filling grooves on the inner and outer rings allow for the incorporation of more balls, thereby enhancing its ability to withstand higher radial loads. The standard radial clearance ensures smooth and efficient operation, while the sheet steel cage increases its resistance to continuous radial loads. Its open design allows for efficient cooling under controlled conditions and easy access to internal components for maintenance.

Maintenance:
This deep-groove ball bearing requires simple but regular maintenance due to its open design. It is important to check the lubrication level and use a high-quality lubricant suitable for the operating conditions. Equipped with a retaining ring, this bearing reduces the risk of axial displacement and premature wear. However, it is recommended to regularly check the radial clearance, noise, and temperature to detect any signs of deterioration. The absence of seals allows for easier inspections and lubrication.

Sealing:
Because it is open, this bearing is exposed to external contaminants, such as dust, particles, or liquids. Since the lubricant is not confined inside, this can also lead to lubricant leakage. It is therefore best suited for clean, controlled environments, as well as those where cooling is critical.

Brand Information:
SKF has been a global leader in the design and manufacture of bearings for over a century. Recognized for its technical expertise, continuous innovation, and commitment to quality, SKF offers a comprehensive range of solutions, from bearings to lubrication systems and related services. With its reliable, high-performance products, SKF supports various industrial sectors, such as the automotive, aerospace, energy, and manufacturing industries, among many others.

Key Features:
- Integrated retaining ring for secure axial retention;
- Filling grooves that allow for more balls to be incorporated into the bearing;
- High radial load capacity, greater than that of a bearing without grooves;
- Simple, versatile, and robust, requiring little maintenance;
- Increased reliability thanks to its robust and simple design.

Applications:
This SKF bearing is ideal for applications requiring high radial load capacity without the need for high speeds. It is used in particular in automotive assemblies, such as wheel hubs, transmissions, and steering mechanisms. It is also found in industrial motors, especially in belt-driven configurations where axial stability is essential. This bearing is suitable for agricultural machinery, such as tractors and harvesters, which are subject to heavy loads. It is also used in conveyor systems, particularly in rollers and components requiring secure axial positioning, as well as in compressors for applications requiring both high load capacity and axial stability.
