RB 6004RS Deep Groove Ball Bearing

The RB 6004RS Deep Groove Ball Bearing is a compact, double-sealed radial bearing designed for reliable support in small motors, gearboxes, and fans. It features a 20 mm bore, 42 mm outer diameter, and 12 mm width, with rubber seals on both sides (RS) to help retain lubrication and resist dust and moisture ingress. As part of the 6000-series, this bearing accommodates radial loads and axial loads in both directions, delivering smooth rotation in confined spaces. Common applications include electric motors, pumps, fans, small conveyors, and other light-duty machinery where a sealed, maintenance-friendly bearing footprint is desirable. The RS seal arrangement enhances longevity in dirty or humid environments by limiting lubricant loss and contamination, while preserving compatibility with standard bearing housings and quick replacement in existing assemblies.
