6302-Z Bearing Product Overview & Core Advantages
The 6302-Z single row deep groove ball bearing represents a fundamental component in precision mechanical systems requiring reliable radial load capacity and consistent performance. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers exceptional dimensional accuracy and rotational precision. Its shielded design (Z-type) provides effective contamination protection while maintaining low friction operation. The bearing's optimized geometry and chrome steel construction ensure high durability and extended service life across diverse operating conditions, making it an ideal choice for applications demanding both reliability and precision engineering.
Model Code Detailed Analysis
| Suffix Code | Technical Meaning | Performance Benefit |

| -Z | Single-sided steel shield | Contaminant protection while maintaining low torque |
6302-Z Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway geometry enables efficient handling of radial loads up to 2675 lbf dynamic capacity, while also accommodating moderate axial loads in both directions. The precisely calculated curvature and ball complement ensure optimal stress distribution.
Precision Engineering: Manufactured to P6 tolerance class with bore diameter tolerance of -0.007mm to 0, this bearing delivers exceptional dimensional stability and running accuracy. The stainless steel cage provides reliable ball guidance and contributes to smooth operation at speeds up to 24,000 rpm.
Enhanced Protection & Lubrication: The Z-shield effectively retains factory-applied grease while excluding larger contaminants. The CN radial internal clearance and factory pre-lubrication ensure immediate operational readiness and consistent performance across the specified temperature range of -30° to 120°C.
Material Excellence: Constructed from chrome steel rings and balls, the bearing offers high hardness, wear resistance, and dimensional stability under load. The combination of materials and precision manufacturing results in a high-performance bearing weighing only 0.084 kg.
