D/W R1810 Bearing Product Overview & Core Advantages
The D/W R1810 is a precision single row deep groove ball bearing designed for demanding applications requiring high reliability and dimensional stability. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its open design facilitates high-speed operation, while its P0 tolerance class and controlled radial internal clearance (CN) ensure consistent performance and smooth running. This bearing is engineered to primarily handle radial loads efficiently in a compact form factor.
D/W R1810 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Interpretation | Technical Implication |
|---|---|---|
| D/W | Manufacturer Series | Designates the specific product line from the manufacturer. |
| R1810 | Bore & Series Code | Indicates a specific bore diameter of 0.3125" within a standard inch series. |
| (No Suffix) | Open, Unshielded | The absence of a seal/shield suffix confirms an open bearing design, optimized for high-speed performance and easy relubrication if required. |
D/W R1810 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior resistance to rust and corrosion, making it ideal for harsh environments, food processing, and medical equipment.
- High-Speed Capability: The open design and precision-ground components minimize friction and heat generation, allowing for a high limiting speed of 63,000 rpm.
- Precision Performance: Built to P0 (ABEC 1) tolerance class with standard CN radial internal clearance, this bearing ensures smooth, quiet, and low-vibration operation, suitable for precision instruments.
- Radial Load Capacity: Engineered to efficiently support radial dynamic loads up to 70 lbf and static loads up to 32 lbf, providing reliable performance in its size class.
- Compliant & Versatile: The bearing is ROHS and REACH compliant and operates effectively within a temperature range of -30°C to 120°C.
