D/W R168 R-2ZS Bearing Product Overview & Core Advantages
The D/W R168 R-2ZS is a single row deep groove ball bearing designed for high-precision applications requiring exceptional reliability. Engineered with inch dimensions, it excels in handling radial loads efficiently within compact spaces. Its construction from stainless steel throughout (rings, balls, and cage) provides excellent corrosion resistance, making it suitable for demanding environments. The inclusion of shielded seals (2ZS) and pre-applied grease lubrication ensures long-term, maintenance-free operation, ideal for applications where reliability is paramount.
D/W R168 R-2ZS Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer prefix (D/W likely refers to a specific series or manufacturer designation). |
| R168 | The basic bearing designation/size code. |
| R- | Flanged outer ring design, facilitating simplified mounting and axial location. |
| 2ZS | Indicates shielded seals on both sides. The "Z" denotes non-contact metal shields, offering effective protection against contaminants while maintaining high-speed capability and low friction. |
D/W R168 R-2ZS Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The integrated flange (Flange outer diameter: 0.42201") allows for easy and secure axial positioning, simplifying assembly and enhancing structural integrity in compact housings.
- Superior Corrosion Resistance: Manufactured entirely from stainless steel, this bearing is highly resistant to rust and corrosion, ensuring long service life in harsh or washdown environments.
- Optimized for High Speeds: The combination of a stainless steel cage, precision-ground components, and non-contact shields enables a high limiting speed of 60,000 rpm, making it suitable for demanding high-speed applications.
- Maintenance-Free Operation: The double-shielded (2ZS) construction retains the factory-applied grease, effectively sealing out contaminants and providing long-lasting, maintenance-free performance across a wide temperature range (-30° to 120 °C).
- Precision Performance: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing delivers consistent and reliable operation for general precision applications.
