Deep groove ball bearing SKF 6204-2RSH/C3W64, 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 deep groove ball bearing ensures reliable and efficient performance, even under demanding operating conditions. Versatile and robust, it withstands radial and axial loads in both directions while ensuring quiet operation. Designed for high-speed applications and fully sealed, it minimizes maintenance requirements.

Features:
This deep-groove ball bearing is equipped with rubber lip seals on both sides, providing excellent protection against external contaminants while effectively retaining the lubricant inside. It is factory-pre-lubricated during assembly with Solid Oil grease developed by SKF and molded into the bearing. It gradually releases oil to ensure continuous lubrication. This solution is particularly well-suited for humid or contaminated environments, offering increased protection against corrosion and eliminating the need for relubrication. Its increased internal radial clearance (C3) allows for high speeds while minimizing internal friction and, consequently, temperature. The sheet steel cage withstands high radial loads by distributing forces evenly across the rings, thereby ensuring optimal performance even under harsh operating conditions. The starting torque is moderate, providing a good balance between reduced friction and effective sealing.

Maintenance:
This bearing requires very little maintenance thanks to its sealed design, which optimally retains the lubricant. The initial lubrication by SKF (Solid Oil) is sufficient to ensure a long service life. However, it is recommended to monitor operating conditions, particularly temperature and vibrations, to detect any potential abnormalities.

Sealing:
This bearing is sealed by acrylonitrile-butadiene rubber lip seals on both sides, which effectively prevent the intrusion of contaminants such as dust and moisture. The RSH seal design incorporates a double lip for optimal sealing, capable of withstanding high-pressure cleaning. This solution extends the bearing’s service life and maintains its performance even in humid or dusty environments. These seals can withstand temperatures up to 120 °C for short periods.
