Deep groove ball bearing SKF 6330 M/C3HVL2071, Outer diameter: 320 mm | Width: 65 mm | Inner diameter: 150 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 is designed to deliver reliable and long-lasting performance under a variety of conditions. It is part of the INSOCOAT series. Bearings in this series are designed to prevent electrical current from passing through the bearing. Thanks to its innovative design and high-quality materials, it ensures optimal operation, even at high speeds. This bearing is particularly well-suited for electrical applications.

Features:
This SKF deep groove ball bearing is a robust product that features a brass cage, ensuring high resistance to loads and impacts. It is designed without seals, making it suitable for clean, controlled environments. Its internal radial clearance rating of C3H indicates that it has increased internal clearance (C3), but within a wider range than that of standard C3 bearings, thus offering greater flexibility for specific applications requiring increased tolerance to thermal and mechanical variations. It features an INSOCOAT coating on the inner ring bore, providing enhanced protection against damage caused by electrical current, particularly through higher impedance achieved by reducing the coated surface area. This ensures high electrical resistance up to 1000 V DC. This product withstands high operating temperatures while maintaining high-quality performance.

Maintenance:
This rigid bearing requires regular maintenance due to its open design. It is essential to check the lubrication—whether by grease or oil—depending on the operating conditions. It is also recommended to conduct regular inspections to monitor noise, temperature, and vibration levels. The bearing must be cleaned if debris or dust is visible. For optimal operation, it is crucial to ensure a clean environment during maintenance.

Sealing:
This single-row ball bearing has no seals against external contaminants such as dust or liquids. Its open design facilitates access to components for direct maintenance but exposes the bearing to the risk of contamination. It is designed to operate in relatively clean environments where the absence of seals does not pose a major problem.
