✅ Double contact seals (DDU) to retain lubricant and block dirt
✅ Pressed steel cage, normal radial internal clearance
✅ Max speed ~8000 rpm; Static 8300 N; Dynamic 13200 N

💡 What is a sealed ball bearing used for in motors and linear slide units? Sealed ball bearings keep lubricant in and contaminants out while supporting radial loads and some axial loads, handy for keeping systems running clean. Here’s how they help in common applications: - Sealed ball bearing design protects grease and extends service life in motors and gearboxes. - Ideal for linear slide unit and conveyor setups where low maintenance and low noise matter. - Works well with hybrid ceramic balls or steel variants depending on speed, load, and precision needs.
