D/W ER1634-2ZS Bearing Product Overview & Core Advantages
The D/W ER1634-2ZS is a single row deep groove ball bearing engineered for precision and reliability in demanding applications. This inch series bearing features a compact design with a 0.75" bore and is constructed entirely from stainless steel, offering excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads with a dynamic load rating of 129 lbf, while the integral shielded design and pre-applied grease ensure long-term, maintenance-free operation. It is an ideal solution for applications requiring high precision, cleanliness, and consistent performance.
D/W ER1634-2ZS Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| ER1634 | Standard bearing designation in the inch series, defining the core dimensions (0.75" bore, 1" OD). | Ensures dimensional interchangeability and easy sourcing. |
| 2Z | Signifies that the bearing is shielded on both sides. | Provides effective protection against contamination while allowing for high-speed operation up to 26,000 rpm. |
| S | Indicates the bearing rings and balls are made of stainless steel. | Offers superior corrosion resistance, making it suitable for harsh environments and applications requiring washdown. |
D/W ER1634-2ZS Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality stainless steel construction provide reliable performance and extended service life under radial loads.
- Optimized for Speed and Longevity: The combination of stainless steel cage material, precision grinding to P0 tolerance class, and CN radial internal clearance contributes to smooth operation and a high limiting speed of 26,000 rpm.
- Sealed and Pre-Lubricated: The non-contact shields (2Z) protect the internal components from dust and debris without significantly increasing friction. The bearing is pre-lubricated with grease, making it ready for immediate use and ensuring smooth operation across its specified temperature range of -30°C to 120°C.
- Lightweight and Compliant: Weighing only 0.0046 kg, it minimizes rotational inertia. The bearing is also compliant with ROHS and REACH regulations.
D/W ER1634-2ZS Bearing Typical Application Areas
- Medical and Dental Equipment: Ideal for handheld tools, pumps, and scanners where corrosion resistance, cleanliness, and reliability are critical.
- Food and Beverage Processing: Suitable for conveyors, mixers, and filling machines that require frequent washdowns and use in corrosive environments.
- Precision Instruments and Optical Devices: Used in encoders, gauges, and small motors demanding high running accuracy and low noise.
- General Industrial Machinery: Applicable in small electric motors, fans, and office automation equipment where compact size and maintenance-free operation are valued.
