629zz Bearing Product Overview & Core Advantages
The 629zz is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. This shielded bearing offers reliable radial load capacity and is engineered for high-speed operation, making it a versatile component for various precision mechanisms. Its ABEC1 precision class ensures consistent performance, while the stainless steel cage and shields provide enhanced durability and corrosion resistance, ideal for applications demanding high reliability and long service life.
629zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Indicates the bearing is fitted with non-contact shields on both sides. This provides effective protection against contaminant ingress while minimizing friction, contributing to the high limiting speed. |
629zz Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and 7 high-grade chrome steel balls are precision-matched to handle significant radial dynamic loads (873 lbf) and moderate axial loads in both directions.
- High-Speed Capability: The lightweight stainless steel cage and low-friction non-contact shields enable a high limiting speed of 28,000 rpm, making it suitable for demanding high-velocity applications.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth, quiet, and vibration-free operation.
- Durable Construction: All critical components, including rings, balls, and cage, are made from corrosion-resistant materials (Chrome Steel and Stainless Steel), enhancing longevity and performance across a wide temperature range (-30° to 110°C).
629zz Bearing Typical Application Areas
This bearing is widely used in applications requiring compact size, high speed, and reliable performance. Key industries and equipment include:
- Small Electric Motors: Spindle motors in fans, power tools, and drones.
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Office Automation: Printers, scanners, and copiers.
- Light-Duty Gearboxes and Transmissions.
