W 619/5-2Z Bearing Product Overview & Core Advantages
The W 619/5-2Z is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. 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 design (2Z) retains factory-applied grease and protects against contaminant ingress, ensuring long-term performance with minimal maintenance. This bearing is ideal for applications demanding high rotational accuracy and durability in a minimal space envelope.
Model Code Breakdown
The model number W 619/5-2Z can be decoded as follows:
- W 619: Indicates the bearing series, a metric, single row deep groove design.
- /5: Specifies the bore diameter of 5 mm.
- -2Z: Denotes that the bearing is equipped with non-contact shields on both sides. This provides effective protection against contaminants while allowing for high-speed operation with low friction and torque.
W 619/5-2Z Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, and the cage, are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments.
- Optimized for Radial Loads: The deep groove raceway and single row design are optimized to carry significant radial dynamic load ratings (171 lbf) efficiently.
- High-Speed Capability: The combination of a low-friction stainless steel cage and non-contact shields contributes to a high limiting speed of 56,000 rpm.
- Pre-Lubricated and Sealed: Factory-filled grease lubrication and the 2Z shields create a sealed-for-life unit, reducing maintenance needs and extending service life.
- Standard Precision: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent and reliable performance for a wide range of general applications.
W 619/5-2Z Bearing Typical Application Areas
