SW SR 188 ZZ Deep Groove Ball Bearing | 9.525 x 22.225 x 7.938 mm (3/8 x 7/8 x 5/16 in) | Double Shielded High-Speed Radial Bearing
The SW SR 188 ZZ bearing is a premium single-row deep groove ball bearing engineered for high-speed, low-friction operation in demanding industrial environments. Featuring precision-machined races crafted from high-carbon chrome steel (52100), this component ensures exceptional load distribution and prolonged service life. The 'ZZ' designation indicates the presence of robust, non-contact metal shields on both sides, which are press-fitted into the outer ring. These shields are crucial for retaining the high-performance grease fill while effectively protecting the internal elements from airborne contaminants, metal filings, and dust—making it ideal for applications requiring maintenance-free operation under moderate temperature conditions.
Designed primarily for radial loads but capable of handling moderate axial loads in either direction, the SR 188 ZZ is a versatile choice for small electric motors, precision instrumentation, HVAC systems, and automated machinery. SW ensures this bearing adheres to P6 (ABEC-3) precision tolerances, guaranteeing optimal running accuracy and minimized vibration. Its compact footprint (9.525 mm bore and 22.225 mm OD) coupled with robust construction provides maximum reliability, minimizing costly downtime and ensuring smooth, efficient power transmission across various OEM and replacement applications. Trust SW engineering for consistent performance.
