The NTN 6805LLU-2RS (61805) Chrome Steel Bearing is a single-row deep-groove ball bearing designed for applications requiring smooth rotation and protection against contamination. Its high-carbon chrome steel construction makes it suitable for compatible bicycle components and other mechanical assemblies requiring a sealed bearing.

Contact Seal Protection. The bearing features nitrile rubber contact seals on both sides, helping prevent dirt, moisture and other contaminants from reaching the internal rolling elements. The contact sealing arrangement provides additional protection in environments where exposed bearings may experience regular contamination.

Reliable Construction. The bearing uses steel balls and a pressed steel cage within precision-manufactured bearing races. Factory-applied grease provides internal lubrication, while the deep-groove design supports radial loads and moderate axial loads in either direction. Before installation, confirm the existing bearing's dimensions, clearance and sealing requirements to ensure compatibility.
