D/W ER1458-2ZS Bearing Product Overview & Core Advantages
The D/W ER1458-2ZS is a precision single row deep groove ball bearing designed for demanding applications requiring high reliability and consistent performance. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently while operating at high speeds. The inclusion of shielded seals (2ZS) and pre-applied grease lubrication ensures long-term, maintenance-free operation, making it an ideal choice for compact, high-precision assemblies.
D/W ER1458-2ZS Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| ER1458 | Standard bearing designation indicating inch dimensions (Bore: 0.625", OD: 0.875", Width: 0.15618") | Defines the core bearing size and geometry for system integration. |
| 2ZS | Bearing is equipped with shields on both sides. | Provides effective protection against contamination while being suitable for high-speed operation (up to 32,000 rpm). |
D/W ER1458-2ZS Bearing Structural Features & Performance Benefits
- Single Row Deep Groove Design: The fundamental geometry provides excellent versatility for handling radial loads, ensuring smooth rotation and low running torque.
- Full Stainless Steel Construction: All components, including the cage, are made from stainless steel, offering superior corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- Shielded Protection (2ZS): The non-contact shields on both sides retain lubricant and effectively exclude larger particulate contaminants, contributing to the bearing's long service life and maintenance-free characteristics.
- Pre-lubricated with Grease: The bearing is factory-filled with grease, which is optimized for the specified temperature range of -30°C to 120°C, providing immediate and reliable operation upon installation.
