W 619/8-2Z Bearing Product Overview & Core Advantages
The W 619/8-2Z is a metric single row deep groove ball bearing designed for high performance in compact spaces. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while its shielded (2Z) design retains factory-fresh grease lubrication, making it a maintenance-free solution for applications demanding reliability and long service life within its specified temperature range.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W 619/8 | Indicates the bearing series and size. A single row deep groove ball bearing with an 8 mm bore diameter. |
| -2Z | Signifies that the bearing is equipped with shields on both sides. This provides effective protection against contamination while being non-contact, minimizing friction and allowing for higher speeds compared to contact seals. |
W 619/8-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments.
- Optimized Radial Load Capacity: The deep groove raceway and single row design are engineered to provide a high dynamic and static radial load rating for its compact size.
- Shielded for Protection & Longevity: The non-contact 2Z shields protect the internal bearing components from dust and other contaminants, while retaining the pre-applied lubricant. This design contributes to a maintenance-free operation and extended service life.
- Pre-lubricated for Immediate Use: Filled with grease at the factory, the bearing is ready for installation and operation, simplifying the assembly process.
- Standard Precision: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring reliable and consistent performance for a wide range of general applications.
W 619/8-2Z Bearing Typical Application Areas
This versatile bearing is ideal for applications requiring a compact, corrosion-resistant, and reliable solution. Common uses include:
- Small Electric Motors and Gear Motors
- Medical and Dental Equipment
- Food Processing and Packaging Machinery
- Precision Instruments and Optical Devices
- Office Automation Equipment (e.g., Printers, Scanners)
- Various Low-Torque Drives and Idler Pulleys
