Deep groove ball bearing SKF 6222 MA/C3B20, Outer diameter: 200 mm | Width: 38 mm | Inner diameter: 110 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 single-row deep groove ball bearing is an ideal choice for demanding industrial environments. Its brass cage makes it resistant to high temperatures and corrosion. Its design optimizes load distribution, while its stabilized ring ensures high precision during operation.

Features:
This SKF ball bearing features a brass cage, which provides good resistance to corrosion and high temperatures, up to 250°C. Its stabilized ring maintains its dimensions under high thermal stresses, ensuring a precise fit in assemblies. This feature is particularly useful in applications where precision is critical to reducing the risk of failure. This bearing is designed to handle heavy radial loads and moderate axial loads, offering a good balance between high-speed performance and load-carrying capacity. The increased radial clearance (C3) allows for better absorption of thermal expansion and deformation under load, thereby reducing internal stresses. This ensures smooth operation and extends the bearing’s service life, even under demanding operating conditions.

Maintenance:
The absence of seals on this bearing facilitates inspections and lubrication. It is crucial to maintain adequate lubrication with high-quality lubricants, depending on operating conditions, to prevent premature wear. The brass cage is highly corrosion-resistant but may oxidize slightly in the presence of moisture. A regular maintenance program should include checks for noise, temperature, and radial play—especially in applications subject to load variations—to quickly detect signs of wear.

Sealing:
This bearing is designed with an open configuration, which means it has no seals. The bearing is therefore fully exposed to various contaminants, dust, debris, etc. Lubricant leakage may also occur. However, the absence of seals simplifies access for maintenance, allowing for easy relubrication.

- Excellent heat resistance (up to 250 °C) thanks to its brass cage and C3 radial clearance
- Stabilized rings for precision and reduced width tolerance
- Low friction thanks to C3 radial clearance
- Uniform load distribution that extends the bearing’s service life

Applications:
This deep-groove ball bearing is designed for a variety of industrial applications. It is particularly well-suited for electric motors, machine tools, and material handling equipment. In transmission systems where precision is required, it ensures optimal performance. Thanks to its brass cage, this bearing is also used in demanding environments, such as ammonia-based refrigeration compressors, where resistance to corrosion and high temperatures is crucial.
