6902zz Bearing Product Overview & Core Advantages
The 6902zz is a single row deep groove ball bearing designed for high-performance industrial applications. This shielded metric bearing features a compact design with a 15 mm bore, 28 mm outside diameter, and 7 mm width, making it ideal for space-constrained assemblies. Engineered with chrome steel rings and balls and a stainless steel cage, it delivers reliable radial load capacity (974 lbf dynamic / 506 lbf static) and smooth operation up to 29,000 rpm. Its ABEC-1 precision and C0 radial clearance ensure consistent performance in demanding environments.
Model Code Breakdown
- 6902: Basic designation indicating a single row deep groove ball bearing with 15mm bore, 28mm OD
- zz: Double shielded design (non-contact metal shields) providing protection from contamination while maintaining high-speed capability
6902zz Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The deep groove raceway geometry enables efficient handling of radial loads and moderate axial loads in both directions, making it versatile for various applications.
High-Speed Capability: The stainless steel cage ensures stable operation at speeds up to 29,000 rpm, while the double zz shields protect the bearing interior without significant speed reduction.
Precision Engineering: Manufactured to ABEC-1 tolerance class with controlled C0 radial clearance (0.003-0.018mm), this bearing delivers consistent performance and long service life.
Enhanced Protection: The double shielded construction provides effective contamination protection, extending bearing life in challenging environments.
