211-2Z Bearing Product Overview & Core Advantages
The 211-2Z is a single row deep groove ball bearing designed for high-performance radial load applications. Engineered with shielded protection and pre-lubrication, it delivers reliable operation in demanding environments. Its compact design and precision manufacturing to P0 tolerance class ensure smooth rotation and long service life, making it an ideal solution for applications requiring consistent performance and minimal maintenance.
211-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 211 | Basic bearing designation indicating metric dimensions (55mm bore, 100mm OD, 21mm width) | Standardized sizing for easy replacement and integration |
| 2Z | Non-contact shields on both sides | Effective contamination protection while maintaining high-speed capability |
211-2Z Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The single row deep groove raceway geometry is engineered to handle significant radial dynamic loads (10,881 lbf) and static loads (9,892 lbf), providing robust support for rotating shafts.
- Shielded & Pre-Lubricated Design: The non-contact 2Z shields effectively exclude contaminants while the factory-applied grease lubrication ensures immediate readiness and extends service intervals, contributing to a maintenance-free operational life.
- High-Speed Nylon Cage: The nylon cage ensures smooth ball guidance, reduces friction, and contributes to the bearing's ability to achieve a limiting speed of 5,600 rpm.
- Precision & Material Integrity: Manufactured from chrome steel for both rings and balls, and built to standard (P0) tolerance with normal (CN) radial internal clearance, this bearing guarantees consistent performance and durability across its specified temperature range (-30°C to 120°C).
211-2Z Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
