689zz Bearing Product Overview & Core Advantages
The 689zz is a metric single row deep groove ball bearing designed for high-performance applications requiring compact dimensions and reliable operation. Featuring shielded construction on both sides, it offers effective protection against contaminant ingress while retaining lubrication. This bearing is engineered to primarily handle radial loads and is characterized by its low friction and smooth operation, making it an ideal choice for applications demanding precision and efficiency. Its compact design, with a 9mm bore and 17mm outside diameter, allows for integration into space-constrained assemblies without compromising performance.
689zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 689 | Bearing series and size designation, indicating a metric deep groove ball bearing with a 9mm bore. |
| zz | Denotes double-shielded construction (shields on both sides). The shields protect against contaminants while allowing for high-speed operation. |
689zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage and optimized internal geometry enables a limiting speed of 36,000 rpm, suitable for demanding high-velocity applications.
- Radial Load Capacity: With a dynamic load rating of 254 lbf and a static load rating of 120 lbf, this bearing provides reliable support for substantial radial forces in compact spaces.
- Contamination Resistance & Lubrication Retention: The 300 series stainless steel shields effectively exclude dust and debris while retaining the necessary lubrication, enhancing bearing service life and reducing maintenance needs.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring consistent performance, low noise, and minimal vibration.
- Material Durability: Components made from chrome steel (rings and balls) and stainless steel (cage and shields) offer excellent resistance to wear and corrosion.
689zz Bearing Typical Application Areas
- Small Electric Motors and Spindle Drives requiring high-speed, low-noise operation.
- Precision Instruments, Optical Devices, and Medical Equipment where compact size and reliability are critical.
- Office Automation Equipment such as printers, scanners, and copiers.
- Computer Cooling Fans and small Power Tools.
- Various Industrial Machinery components where space-saving ball bearings are specified.
