SW 697-ZZ Deep Groove Ball Bearing | 7x17x5 mm | High-Speed Miniature Bearing
The SW 697-ZZ is a precision deep groove ball bearing engineered specifically for applications demanding both compactness and high rotational speed stability. Featuring the 6900 thin-section geometry, this bearing (7 mm bore, 17 mm outer diameter, 5 mm width) minimizes housing space requirements while delivering exceptional radial and moderate axial load support. Manufactured from high-carbon chromium steel (GCR15 equivalent), it ensures superior hardness and wear resistance, maintaining the P6 (ABEC-3) precision standard required for critical industrial instrumentation and small motor assemblies. The internal clearance (C3 standard) is optimized to accommodate thermal expansion, reducing internal stresses and extending operational life under continuous duty cycles.
Equipped with dual non-contact metal shields ('ZZ'), the 697-ZZ offers robust protection against common industrial contaminants such as dust and metallic particles, making it virtually maintenance-free. These shields effectively retain the high-quality synthetic grease, ensuring lubrication reliability throughout the bearing's service life, resulting in reduced friction and optimized energy efficiency. Chosen by OEMs for dental equipment, precision robots, and measuring instruments, the SW 697-ZZ guarantees reliable performance, minimizing downtime and vibration in highly sensitive applications.
