619/8-2Z Bearing Product Overview & Core Advantages
The 619/8-2Z is a metric miniature deep groove ball bearing designed for high-precision applications requiring compact dimensions and reliable performance. This single row bearing excels at handling primarily radial loads and is characterized by its shielded design and superior P6 tolerance class. Its compact 8mm bore, 19mm outside diameter, and 6mm width make it an ideal solution for space-constrained assemblies demanding high rotational accuracy and smooth operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 619 | Series designation for extra-small, ultra-thin deep groove ball bearings. |
| 8 | Nominal bore diameter of 8 mm. |
| 2Z | Bearing is equipped with shields on both sides. This provides effective protection against contamination while allowing for higher limiting speeds compared to contact seals. |
619/8-2Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with a CN radial internal clearance, this bearing ensures precise running accuracy and minimal vibration, contributing to system stability.
- Optimized Load Capacity: The deep groove raceway and chrome steel construction provide a dynamic load rating of 328 lbf and a static load rating of 105 lbf, making it robust for its compact size.
- Ready-to-Use & Long-Lasting: The bearing is pre-lubricated with grease and features non-contact shields (2Z), offering protection from contaminants and providing a maintenance-free service life within its specified operating conditions.
- Corrosion-Resistant Cage: The stainless steel cage ensures excellent durability and reliable performance, contributing to smooth operation at the limiting speed of 43,000 rpm.
