Deep groove ball bearing SKF 6208-2RS1TN9/C3VE167, Outer diameter: 80 mm | Width: 18 mm | Inner diameter: 40 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 designed to withstand high radial loads as well as moderate axial loads in both directions. Its innovative design features a groove in the outer ring to accommodate a retaining ring for easy installation. Equipped with rubber seals on both sides, it offers excellent protection against contaminants and ensures a long service life.

Features:
Featuring a glass-fiber-reinforced polyamide cage, this single-row deep groove ball bearing ensures smooth and quiet operation, even at high speeds. The increased internal radial clearance (C3) reduces internal friction, thereby optimizing performance and minimizing rolling resistance during ring expansion. Nitrile-butadiene rubber (NBR) seals provide effective protection against contaminants such as dust and moisture, ensuring excellent sealing and extending the bearing’s service life. This bearing is ideally suited for industrial environments where durability and noise reduction are paramount. For added convenience, a groove is machined into the outer ring to accommodate a circlip (retaining ring).

Maintenance:
This deep-groove ball bearing requires little maintenance thanks to its rubber contact seals. However, it is recommended to periodically monitor operating conditions—such as temperature, vibration, alignment, and the condition of the seals—to detect any potential issues early on. Regular cleaning of the outer surface helps prevent the buildup of contaminants that could reduce heat dissipation.

Sealing:
It is equipped with nitrile-butadiene rubber (NBR) lip seals on both sides. These seals effectively retain the lubricant inside the bearing while preventing the intrusion of fine particles (dust, fumes, fibers, etc.) or liquids (water, diluted acids, cutting oil, etc.). This ensures long-lasting protection of the rolling elements even in humid or dusty environments. However, the presence of these seals introduces slight resistance that may limit the bearing’s maximum rotational speed and reduce overall efficiency.
