D/W R144W.0937-2ZS Bearing Product Overview & Core Advantages
The D/W R144W.0937-2ZS is a single row deep groove ball bearing designed for precision applications requiring high reliability in compact spaces. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded (2Z) construction on both sides retains lubricant and protects against contamination, ensuring consistent performance and extended service life without maintenance. This makes it an ideal precision bearing for demanding environments.
D/W R144W.0937-2ZS Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer's prefix (D/W). |
| R144W | Bearing series and size designation. |
| .0937 | Bore Diameter in inches (0.0937"). |
| 2Z | Bearing is shielded on both sides. This provides effective protection against contaminants while minimizing friction, contributing to its high limiting speed. |
| S | Indicates the bearing is made from stainless steel, offering superior corrosion resistance. |
D/W R144W.0937-2ZS Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and stainless steel cage provide stable operation and high running accuracy, suitable for high-speed applications up to 85,000 rpm.
- Effective Sealing: The non-contact shields (2Z) on both sides effectively retain the pre-applied grease lubrication and exclude dust and other particulates, enabling a maintenance-free, long service life.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, making the bearing suitable for use in humid or corrosive environments and ensuring consistent performance across its temperature range of -30°C to 120°C.
- Precision & Reliability: Manufactured to P0 tolerance class with standard CN radial internal clearance, this bearing delivers reliable and precise performance for a wide range of industrial applications.
