W 619/5 X-2Z Bearing Product Overview & Core Advantages
The W 619/5 X-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 primarily radial loads efficiently, while its shielded design ensures long-term performance. This bearing is characterized by its compact dimensions (5mm bore, 13mm OD, 5mm width) and is pre-lubricated with grease, making it a ready-to-install, low-maintenance solution for applications demanding high rotational accuracy and durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| W 619/5 | Indicates a deep groove ball bearing series with a 5 mm bore diameter. |
| X | Specifies a stainless steel construction for the bearing rings and balls. |
| 2Z | Denotes shielded on both sides. This non-contact seal effectively protects against contamination while minimizing friction, contributing to the high limiting speed. |
W 619/5 X-2Z Bearing Structural Features & Performance Benefits
Corrosion-Resistant Construction: Manufactured from stainless steel for rings, balls, and cage, this bearing is ideal for applications exposed to moisture or corrosive environments, ensuring long service life.
Shielded for Protection: The 2Z shields on both sides protect the internal components from dust and other contaminants, while the pre-applied grease lubrication ensures smooth operation from the start, making it a maintenance-free unit.
Precision and Speed: Built to P0 tolerance class and standard CN radial internal clearance, it provides reliable and precise rotation. The combination of the deep groove raceway and shielded design allows for a high limiting speed of 56,000 rpm.
Compact and Lightweight: With a minimal cross-section and a weight of only 0.0029 kg, it is perfectly suited for space-constrained and weight-sensitive designs.
