SW 6304-ZZ Deep Groove Ball Bearing | 20x52x15mm | Shielded for High-Speed Applications
The SW 6304-ZZ is a high-performance single-row deep groove ball bearing, engineered for robust operation in moderate-to-heavy load industrial applications. This bearing features superior geometric precision and uses high-purity bearing steel (typically SAE 52100 equivalent) for exceptional hardness, load distribution, and operational longevity. The 6300 series designation indicates a heavier-duty profile compared to the 6200 series, making it highly resilient to radial and moderate axial loads. The 'ZZ' designation confirms the presence of two non-contacting metal shields, effectively retaining the premium factory lubricant while offering superior protection against coarse contaminants and minimizing running friction compared to rubber seals (2RS).
Ideal for critical equipment such as high-output electric motors, heavy-duty pumps, industrial compressors, and automotive transmissions, the SW 6304-ZZ ensures maximum uptime and reduced maintenance frequency. Precision manufacturing processes guarantee low noise levels and minimal vibration, meeting P0/ABEC 1 tolerance standards or better. Choosing this shielded bearing guarantees reliable performance in environments where robust protection and sustained high speeds are required, delivering the necessary efficiency and durability for demanding industrial machinery.
