211SZZ Bearing Product Overview & Core Advantages
The 211SZZ is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Engineered with shielded construction on both sides, it offers reliable protection against contaminant ingress. This bearing excels at handling primarily radial loads and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and dependable operation. Its compact design, combined with high-grade chrome steel components, provides an excellent balance of durability and cost-effectiveness for general machinery use.
Model Code Breakdown
- 211: Standard designation for the bearing series, indicating specific internal dimensions (55mm bore, 100mm OD, 21mm width).
- S: Denotes a shielded bearing. This suffix indicates the presence of steel shields on both sides to retain lubrication and exclude larger contaminants.
- ZZ: A common alternative designation for double-shielded construction, confirming the bearing is sealed on both sides with non-contact metal shields.
211SZZ Bearing Structural Features & Performance Benefits
Robust Construction: Fabricated entirely from chrome steel, including the rings, balls, and cage, this bearing ensures high strength and resistance to wear, contributing to a long operational lifespan.
Effective Contamination Protection: The double-shielded (ZZ) design effectively protects the bearing's interior from dust and other particles, making it suitable for environments where complete sealing is not required but basic protection is essential.
High Load Capacity: With a dynamic load rating of 10881 lbf and a static load rating of 9892 lbf, it is capable of handling significant radial loads in various applications.
Ready-to-Use: The bearing comes unlubricated, providing flexibility for the user to apply a lubricant best suited for the specific application conditions and operating speed, which is limited to 7,000 rpm.
