6703zz Bearing Product Overview & Core Advantages
The 6703zz is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. Featuring shielded construction (ZZ) on both sides, this bearing offers effective protection against contaminant ingress while maintaining low friction. Manufactured to ABEC-1 precision tolerance with optimized radial internal clearance (C0), it delivers smooth operation and extended service life. Its compact cross-section (4mm width) makes it ideal for space-constrained applications while maintaining excellent radial load capacity and operational stability.

| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 67 | Extra-thin series, ultra-compact design | Minimizes space requirements in compact assemblies |
| 03 | Bore diameter: 17mm | Standard metric sizing for shaft compatibility |
| ZZ | Double-shielded construction | Provides effective contamination protection for extended bearing life |
6703zz Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables excellent radial load capacity (225 lbf dynamic / 148 lbf static) while accommodating minor axial loads. This makes the bearing suitable for various loading conditions in precision applications.
Shielded Protection System: The dual ZZ shields provide effective sealing against dust and particulate contamination while maintaining low operating torque. This protection extends lubricant life and reduces maintenance requirements.
Precision Manufacturing: Manufactured to ABEC-1 tolerance class with controlled radial internal clearance (C0: 0.003-0.018mm), ensuring consistent performance and smooth operation across the entire temperature range (-30°C to 110°C).
Material Excellence: Constructed with chrome steel rings and balls combined with a stainless steel cage, providing excellent durability and corrosion resistance. The combination delivers reliable performance up to the limiting speed of 11,000 rpm.
