D/W R1810 R Bearing Product Overview & Core Advantages
The D/W R1810 R is a single row deep groove ball bearing designed for high-precision applications requiring superior performance in a compact form factor. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing is engineered to primarily support radial loads and is characterized by its open design and P0 tolerance class, ensuring reliable operation and dimensional consistency. Its small cross-section and inch dimensions make it ideal for applications where space is at a premium without compromising on load capacity or rotational accuracy.
D/W R1810 R Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer's prefix (DWB / Dynaroll). |
| R1810 | The basic bearing designation, indicating a specific size series with a 0.3125" bore and 0.5" outside diameter. |
| R | This suffix denotes a flanged outer ring. The flange simplifies mounting and positioning within a housing. |
| (No Seal Suffix) | The absence of a seal suffix (like 2Z or RS) confirms an open bearing design, allowing for higher limiting speeds and customization of lubrication. |
D/W R1810 R Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The integrated flange on the outer ring provides precise axial location and simplifies housing design, reducing assembly time and cost. The flange outer diameter is 0.54701" with a thickness of 0.03098".
- High-Grade Stainless Steel Construction: All components, including rings, balls, and the stainless steel cage, are made from stainless steel, providing excellent resistance to corrosion and enabling use in harsh environments within a temperature range of -30°C to 120°C.
- Optimized for High-Speed Operation: The open, single-row deep groove ball bearing design and precision construction contribute to a high limiting speed of 63,000 rpm, making it suitable for high-speed applications.
- Precision and Reliability: Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing ensures consistent performance, low noise, and smooth running.
- Application-Specific Lubrication: Supplied without lubrication, this allows engineers to select a specialized grease or oil best suited for the specific operational requirements, such as extreme temperatures or specific chemical compatibility.
