C&U Bearings Company 6318Rs Radial Ball Bearing

C&U 6318RS radial ball bearing is a standard deep‑groove bearing with a 90 mm bore, a 190 mm outer diameter, and a 43 mm width, making it a common footprint for replacement in a wide range of rotating equipment. This 6318 size is typically used to support radial loads in motors, gearboxes, pumps, and fans where reliable, low‑friction operation is required at moderate to high speeds. The RS designation indicates a sealed variant suitable for helping retain lubrication and protect against contaminants, which can expand service life in challenging environments. When installed in housings and shafts designed for 90×190×43 mm bearings, it offers predictable performance and compatibility with widely available replacement parts. C&U Bearings markets a broad line of ball bearings for general industrial use, and the 6318RS fits within that portfolio as a standard, readily interchangeable option for applications demanding a robust, mid‑sized radial bearing.
