Deep groove ball bearing SKF 6207-2RZTN9/HC5C3WT, Outer diameter: 72 mm | Width: 17 mm | Inner diameter: 35 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 deep-groove ball bearing is designed to deliver high performance while being protected against electrical currents. Thanks to its silicon nitride rolling elements, polyamide cage, sealing, and high-quality lubrication, it is intended for specific applications. This hybrid model is ideal for supporting radial and axial loads, meeting the demands of the most challenging applications where reliability is essential.

Features:
This single-row ball bearing is distinguished by its use of steel rings and silicon nitride (Si3N4) rolling elements, ensuring optimal electrical insulation and improved wear resistance. Designed to withstand high radial loads and moderate axial loads in both directions, this bearing is ideal for high-speed applications thanks to its increased internal clearance (C3), which facilitates heat dissipation. The glass-fiber-reinforced polyamide cage helps minimize friction, thereby increasing speed capacity while extending the bearing’s service life. It is pre-lubricated with a high-performance polyurea-thickened grease that withstands temperatures ranging from -40 °C to +160 °C. In addition, it features two non-contacting nitrile seals for optimal protection against contamination.

Maintenance:
This bearing is equipped with nitrile seals designed to retain the lubricant while limiting the ingress of solid and liquid contaminants. Except in rare cases, relubrication is not necessary. To ensure optimal performance, however, it is advisable to monitor temperature, vibration, alignment, radial clearance, and overall cleanliness. These checks allow for the early detection of any abnormalities, ensuring an extended service life.

Sealing:
The RZ seals integrated into this bearing are designed to provide optimal sealing without creating friction. Engineered to effectively retain lubricant while preventing the ingress of contaminants and moisture, these non-contacting seals ensure superior performance even in harsh environments. However, they are not resistant to high-pressure water jets.

Brand Information:
Founded in 1907, SKF is a leading player in the field of bearings and industrial maintenance solutions. With a presence in over 130 countries and an extensive distribution network, the brand offers high-quality products designed to improve the performance of industrial equipment.

Key Features:
- Silicon nitride balls for protection against electrical discharges.
- Non-contacting nitrile seals for long-lasting sealing and minimal friction.
- C3 radial clearance for optimal performance at high speeds.
- Polyamide cage for improved wear resistance and reduced risk of seizure.
- High-quality lubrication effective over a wide temperature range.

Applications:
It is particularly well-suited for electric motors, where it offers low friction and excellent insulation against stray currents, thereby effectively protecting the equipment. For example, in circulation pump motors, it ensures reliable performance while minimizing wear. It is also ideal for pumps and compressors, particularly in HVAC systems, where vibration reduction is crucial for ensuring quiet and stable operation. Furthermore, for high-speed applications, such as machine tool spindles, the lightweight nature of the silicon nitride elements helps improve overall performance. Finally, thanks to its seals that protect against contaminants, this bearing is perfectly suited for dusty or humid environments, such as those found in agricultural machinery or construction equipment, ensuring increased durability even under harsh conditions.
