629-2Z Bearing Product Overview & Core Advantages
The 629-2Z is a single row deep groove ball bearing designed for high-performance applications requiring reliability and precision. Its key advantage lies in its ability to efficiently handle radial loads while offering a compact design. The inclusion of shielded seals (2Z) on both sides protects the bearing from contamination, making it suitable for applications demanding high operational cleanliness and longevity. Manufactured to a P6 tolerance class, it ensures high running accuracy, making it an excellent choice for precision instruments and machinery where consistent performance is critical.
629-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Prefix / Basic Code | 629 | Indicates a standard single row deep groove ball bearing with a 9 mm bore diameter. |
| Suffix | 2Z | Denotes shielded seals on both sides. This provides effective protection against contaminants while allowing for high-speed operation. |
629-2Z Bearing Structural Features & Performance Benefits
Robust Construction for Radial Loads: The single row deep groove raceway geometry is optimized to carry significant radial dynamic load ratings (1068 lbf), providing stable and reliable operation.
Contamination Protection & Long Service Life: The 2Z shields retain the factory-applied grease lubrication and exclude dust and other particulates, significantly extending the bearing's service life and enabling maintenance-free operation in many environments.
High-Speed Capability & Precision: The combination of a stainless steel cage, high-grade chrome steel components, and P6 tolerance ensures smooth operation at high limiting speeds (30,000 rpm) with minimal vibration and noise.
Wide Operating Temperature Range: With a specified operating range from -30°C to 120°C, this bearing is suitable for a variety of industrial climates and conditions.
629-2Z Bearing Typical Application Areas
The 629-2Z is ideally suited for a wide range of applications where compact size, reliability, and protection from contamination are key. Common uses include:
- Small Electric Motors (e.g., fans, blowers, power tools)
- Precision Instruments and medical devices
- Office Automation Equipment (e.g., printers, scanners)
- Light-duty gearboxes and transmission systems
- Various industrial machinery requiring high-speed and low-maintenance components.
