210SZZST Bearing Product Overview & Core Advantages
The 210SZZST is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing features a shielded design on both sides, offering reliable protection against contamination. Engineered for primarily radial loads, it is characterized by its high precision (ABEC 1 | ISO P0 tolerance class) and robust construction using chrome steel for all critical components. Its compact design and high limiting speed make it an ideal, cost-effective solution for applications requiring reliable, long-lasting operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 210 | Basic bearing series, defining the dimensional boundary (Bore: 50mm, OD: 90mm, Width: 20mm). |
| ZZ | Indicates the bearing is shielded on both sides. This provides effective protection against solid contaminants while generating lower friction than contact seals. |
| S | Specifies the radial internal clearance group. In this case, it corresponds to the standard CN clearance. |
| T | Denotes that the bearing cage is made of Fiberglass Reinforced Polyamide (Nylon), contributing to lower weight, quieter operation, and suitability for higher speeds. |
210SZZST Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The deep groove raceway and single row construction are engineered to efficiently handle high radial dynamic and static load ratings (8790 lbf and 7756 lbf respectively), ensuring stable operation under significant stress.
- High-Speed Capability: The combination of a lightweight polyamide cage (T) and the low-friction shielded (ZZ) design enables a high limiting speed of 8,000 rpm, making it suitable for demanding rotational applications.
- Robust Construction & Precision: Manufactured entirely from chrome steel, this bearing offers high strength and durability. It is produced to ABEC 1 | ISO P0 precision class, guaranteeing consistent performance and smooth running.
- Contamination Protection: The non-contact steel shields (ZZ) on both sides effectively protect the internal components from dust and debris, extending the bearing's service life in unclean environments.
210SZZST Bearing Typical Application Areas
This versatile bearing is widely used across various industries, including:
- Electric Motors and Small Gearboxes
- Material Handling Equipment such as conveyor rollers
- Agricultural Machinery
- Industrial Fans and Blowers
- Automotive Components (e.g., alternators, idler pulleys)
