The SW 6304-2RS is a robust and highly versatile Deep Groove Ball Bearing engineered for demanding industrial environments. Featuring a standard bore of 20mm, an outer diameter of 52mm, and a width of 15mm, this bearing is manufactured using high-quality chrome steel (typically 52100 grade) for exceptional hardness and extended service life. The crucial 2RS designation signifies double lip contact seals made of synthetic rubber, providing superior protection against dust, moisture, and contaminants while ensuring the pre-filled, high-performance grease remains contained. This configuration minimizes maintenance requirements and extends the effective operating time in applications requiring moderate radial and axial load capacity.
Optimized for reliability and operational efficiency, the SW 6304-2RS excels in applications demanding high rotational precision and quiet operation, such as electric motors, pumps, gearboxes, and conveyer systems. As a core component in maintaining industrial uptime, SW bearings are subjected to rigorous quality control standards, guaranteeing consistent performance even at limiting speeds up to 14,000 RPM (grease lubricated). Choosing the SW 6304-2RS ensures reduced downtime, predictable maintenance schedules, and a strong return on investment through superior durability and adherence to ISO dimensional standards.
