The SW 6307-2RS deep groove ball bearing is engineered for demanding industrial applications requiring exceptional durability and minimal maintenance. Featuring a 35mm bore, 80mm outer diameter, and 21mm width, this precision component adheres strictly to ISO 15 standards for dimensional accuracy and tolerance. The '2RS' designation indicates robust contact seals made from high-quality nitrile rubber (NBR), factory-filled with premium lithium-complex grease. This configuration ensures superior contaminant exclusion (dust, moisture) while retaining lubrication, maximizing operational life, and preventing premature failure in wet or dirty environments. The optimized internal geometry and high-grade bearing steel construction provide a dynamic load rating (Cr) of approximately 32.5 kN, suitable for heavy radial and moderate axial loads.
Designed to reduce total cost of ownership (TCO) by extending service intervals, the SW 6307-2RS is the ideal solution for critical rotating machinery across diverse sectors. It is extensively used in electric motors, industrial pumps, gear reducers, conveyor systems, and agricultural machinery where reliability is paramount. The sealed design eliminates the need for periodic relubrication, simplifying maintenance procedures and reducing downtime. Choosing SW means investing in certified quality, exceptional speed capability (up to 8,500 rpm with grease), and consistent performance necessary to sustain continuous operation in high-utilization production settings.
