SW 6004-2RS Deep Groove Ball Bearing | 20x42x12mm | High-Speed Motor and Pump Rated
The SW 6004-2RS Deep Groove Ball Bearing is engineered for high-performance industrial applications requiring reliability and sustained operation under moderate radial and thrust loads. Featuring a precision ground raceway and constructed from robust high-carbon chromium steel (typically SAE 52100), this bearing conforms strictly to ISO standards for dimensional accuracy (20mm bore, 42mm outer diameter, 12mm width). The dual contact rubber seals (2RS) provide superior containment of the factory-applied lithium-based grease while effectively barring contaminants like dust, moisture, and debris, making it ideal for gearboxes, electric motors, power tools, and small conveyor systems where uptime is critical.
SW bearings are designed to provide an optimal balance of cost-effectiveness and durability, ensuring a long service life even in moderately harsh environments. The non-contact design variant allows for higher speed capabilities compared to open or single-sealed types, maintaining lower operating friction and heat generation. Choosing the 6004-2RS ensures reduced maintenance cycles and minimized risk of premature bearing failure, offering dependable rotational support across a wide range of operational speeds essential for continuous manufacturing processes.
