6708zz Bearing Product Overview & Core Advantages
The 6708zz is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. This metric bearing is characterized by its compact cross-section, with a 6 mm width, making it an ideal solution for space-constrained assemblies. Its shielded (ZZ) construction provides effective protection against contaminant ingress, preserving lubricant integrity and extending service life. Manufactured to ABEC-1 precision tolerances, it offers a dependable balance of performance and value, capable of handling significant radial loads with a dynamic rating of 565 lbf.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6708 | Basic bearing designation indicating a deep groove ball bearing with a 40 mm bore diameter and 50 mm outside diameter. |
| zz | Denotes shielded construction on both sides. The shields protect the internal components from large particulate contaminants while retaining the factory-applied lubricant. |
6708zz Bearing Structural Features & Performance Benefits
- Robust Construction: Built with chrome steel rings and balls and a stainless steel cage, this bearing offers high strength, durability, and corrosion resistance for the cage, ensuring stable operation.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to efficiently support radial dynamic loads up to 565 lbf and static loads of 502 lbf.
- Shielded Protection: The non-contact ZZ shields provide a high degree of contamination exclusion without significantly increasing friction, contributing to a limiting speed of 5,000 rpm.
- Precision & Clearance: Manufactured to ABEC-1 tolerance class with a standard C0 radial internal clearance (0.006mm to 0.020mm), ensuring consistent performance and smooth running in general-purpose applications.
6708zz Bearing Typical Application Areas
This versatile deep groove ball bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor System Idler Rolls
- Office Automation Equipment (Printers, Scanners)
- Medical Devices and Low-Power Drives
- Agricultural Machinery Accessories
