619/3-2Z Bearing Product Overview & Core Advantages
The 619/3-2Z is a metric miniature deep groove ball bearing designed for compact applications requiring reliable performance. Featuring a single row design with shielded seals (2Z), it offers effective protection against contamination while maintaining low friction. This bearing is engineered to primarily handle radial loads and is characterized by its small dimensions (3mm bore, 8mm OD, 3mm width), making it ideal for applications where space is limited. Manufactured to ABEC 1 | ISO P0 tolerance class, it provides consistent operation and is supplied without lubrication for applications requiring specific grease compatibility.
619/3-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 619 | Series designation for miniature deep groove ball bearings |
| 3 | Bore diameter: 3 mm |
| 2Z | Shielded both sides - Provides effective contaminant protection while maintaining low operating torque |
619/3-2Z Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: The single row construction with minimal cross-section enables integration into space-constrained assemblies while reducing overall weight.
- Shielded Protection: The 2Z shields on both sides effectively exclude contaminants while allowing higher limiting speeds (70,000 rpm) compared to contact seals.
- Precision Performance: Manufactured to ABEC 1 | ISO P0 tolerance standards with CN radial internal clearance, ensuring consistent running accuracy and smooth operation.
- Material Quality: All-steel construction using chrome steel for rings, balls, and cage provides durability and consistent mechanical properties.
- Dry Operation Ready: Supplied without lubrication for applications requiring specific grease compatibility or where dry operation is preferred.
