The SW B1620 is engineered for critical industrial applications demanding superior longevity and rotational accuracy. Classified as a high-precision Deep Groove Ball Bearing (DGBB), this unit features SW proprietary high-carbon chromium steel construction, ensuring exceptional resistance to fatigue and static load stress. Optimized internal geometry and super-finished raceways drastically reduce friction coefficient, resulting in lower operating temperatures and maximized energy efficiency. The B1620 utilizes a specialized Polyamide 66 reinforced cage (TNH type) to maintain optimal ball spacing under high-speed operation and rapid acceleration/deceleration cycles, making it ideal for electric motors, high-speed pumps, and precision machine tools.
Selecting the SW B1620 guarantees reduced total cost of ownership (TCO) through extended maintenance intervals and minimized unplanned downtime. This product is manufactured to ABEC 3/ISO P6 tolerance standards, featuring C3 internal radial clearance suitable for standard fitting practices and moderate temperature differentials. Utilizing advanced sealing technology (Z or RS depending on specific suffix), the B1620 ensures lifetime lubrication integrity and protection against harsh environmental contaminants, delivering reliable performance across heavy-duty conveyance systems, gearboxes, and agricultural machinery. Specify SW B1620 for guaranteed reliability and sustained operational excellence.
