Single-row deep groove ball bearings with seals or shields on one or both sides are particularly versatile, operate with low friction, are optimized for low noise and vibration levels, and are suitable for high speeds. They can accommodate radial-axial combined loads in both directions, are easy to install, and require less maintenance than other types of bearings. The integrated seal can significantly extend the service life of the bearing by retaining the lubricant and repelling contaminants. The integrated seal enhances bearing longevity. Simple, versatile, and robust design. Low friction and high rated speeds. Capable of handling radial-axial combined loads in both directions. Very low maintenance requirements.
