D/W ER1038-2ZS Bearing Product Overview & Core Advantages
The D/W ER1038-2ZS is a precision single row deep groove ball bearing designed for high-performance applications. Engineered with stainless steel components and shielded construction, it offers reliable operation and excellent resistance to corrosion. This bearing is optimized to handle primarily radial loads efficiently while maintaining smooth rotation. Its compact design and high limiting speed of 43,000 rpm make it an ideal choice for applications demanding high reliability and long service life in challenging environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| ER1038 | Basic bearing designation indicating inch dimensions (0.375" bore × 0.625" OD × 0.15618" width) |
| 2Z | Non-contact shields on both sides providing effective contamination protection while maintaining low friction |
| S | Stainless steel construction for enhanced corrosion resistance |
D/W ER1038-2ZS Bearing Structural Features & Performance Benefits
- Superior Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage) ensuring excellent performance in corrosive environments and facilitating cleaning procedures.
- Effective Contamination Protection: The non-contact shields (2Z) provide reliable protection against dust and particulate contamination while minimizing friction and heat generation.
- High-Speed Capability: Optimized design with stainless steel cage and precision manufacturing enables operation at limiting speeds up to 43,000 rpm.
- Maintenance-Free Operation: Factory-preloaded grease lubrication combined with shielded construction provides long-term, maintenance-free performance across the temperature range of -30°C to 120°C.
- Precision Performance: Manufactured to ABEC 1 (P0) tolerance class with CN radial internal clearance, ensuring consistent, reliable operation in precision applications.
