S628 Bearing Product Overview & Core Advantages
The S628 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. This bearing is designed to primarily handle radial loads and is characterized by its compact design with an 8 mm bore, 24 mm outside diameter, and 8 mm width. Its ABEC1 precision class and optimized internal geometry ensure smooth, quiet operation, making it an ideal choice for applications demanding consistent performance and long service life.

S628 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The use of stainless steel for all critical components (rings, balls, and cage) provides superior resistance to rust and corrosion, extending bearing life in harsh environments.
- Optimized Deep Groove Raceway: The deep groove geometry enables efficient handling of radial loads and moderate axial loads in both directions.
- Precision Performance: Manufactured to ABEC1 tolerance class, this bearing ensures reliable, low-vibration, and low-noise operation, which is critical for sensitive equipment.
- High-Speed Capability: With a limiting speed of 25,200 rpm, the bearing is suitable for high-velocity applications. The integral stainless steel cage and optimized internal design contribute to this high-speed performance.
- Controlled Internal Clearance: The standard MC3 radial internal clearance (0.002mm to 0.013mm) provides an optimal fit for most general applications, ensuring smooth rotation and minimal friction.
