Its key advantages include superior corrosion resistance, a shielded design for contaminant protection, and pre-lubrication for long service life, making it ideal for applications demanding high precision and durability in a miniature format.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| D/W | Manufacturer series designation. |
| RW1-4 | Specific size code indicating the bearing dimensions (Bore: 0.07813", OD: 0.25", Width: 0.17189"). |
| 2Z | Signifies a bearing with shields on both sides. This provides effective protection against solid contaminants while allowing for higher speeds compared to contact seals. |
| S | Indicates the bearing rings and balls are manufactured from stainless steel, providing excellent corrosion resistance. |
D/W RW1-4-2ZS Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from stainless steel, including rings, balls, and cage, this bearing offers superior resistance to rust and corrosion, ensuring long-term performance in harsh environments.
Optimized Load Capacity: The single row deep groove raceway is precision-engineered to efficiently carry radial loads, with a dynamic load rating of 37 lbf and a static load rating of 11 lbf.
High-Speed Capability: The non-contact shielded (2Z) design and grease lubrication contribute to a high limiting speed of 85,000 rpm, making it suitable for high-speed miniature applications.
Maintenance-Free Operation: The integral shields retain the factory-applied grease, protecting the bearing from contamination and providing long-lasting, lubricated-for-life service under normal operating conditions within the specified temperature range.
