625zz Bearing Product Overview & Core Advantages
The 625zz shielded ball bearing is a precision single row deep groove ball bearing designed for reliable performance in compact applications. Engineered to primarily handle radial loads, its metric dimensions (5mm bore, 16mm OD, 5mm width) make it an ideal solution for space-constrained designs. Manufactured to ABEC1 tolerance class, it offers a robust balance of performance and value, ensuring smooth operation and high reliability in a wide range of industrial and commercial equipment.

625zz Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and complement of 7 precision balls enable efficient radial load distribution and smooth rotation.
- High-Speed Capability: The combination of a low-friction stainless steel cage, non-contact shields, and optimized internal geometry allows for a limiting speed of 36,000 rpm.
- Precision and Durability: Components made from chrome steel (rings and balls) offer high wear resistance and durability, ensuring consistent performance under the specified dynamic and static load ratings.
- Contamination Protection: The 300 series stainless steel shields help retain lubrication and exclude larger particulate contaminants, extending service life.
- Standard Internal Clearance: The MC3 radial internal clearance (0.002mm to 0.013mm) is suitable for most general applications, providing stable operation across a range of operating conditions.
