D/W R6-5-2ZS Bearing Product Overview & Core Advantages
The R6-5-2ZS is a high-precision, single row deep groove ball bearing designed for demanding applications. Engineered from stainless steel throughout, it offers excellent corrosion resistance. Its core strength lies in its ability to handle primarily radial loads efficiently, while its shielded (2Z) construction and pre-lubrication ensure long-term, maintenance-free operation. This bearing is characterized by its compact design, making it an ideal choice for applications requiring high reliability and consistent performance within a wide temperature range.
D/W R6-5-2ZS Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R6 | Series designation for inch-size deep groove ball bearings. |
| 5 | Bore diameter code for 0.5". |
| 2Z | Bearing is equipped with non-contact shields on both sides. This provides effective protection against contamination while minimizing friction, contributing to the high limiting speed. |
| S | Indicates the bearing rings and balls are made from stainless steel, offering superior corrosion resistance. |
D/W R6-5-2ZS Bearing Structural Features & Performance Benefits
- Robust Construction: The single-row design with a deep groove raceway and a stainless steel cage provides stable operation and reliable radial load capacity.
- High-Speed Capability: The combination of non-contact shields (2Z) and optimized grease lubrication allows for a high limiting speed of 36,000 rpm, making it suitable for high-speed applications.
- Corrosion Resistance & Longevity: Manufactured entirely from stainless steel, this bearing is ideal for harsh environments, resisting corrosion and ensuring a long service life.
- Maintenance-Free Operation: The bearings are pre-lubricated and sealed for life with shields, eliminating the need for re-lubrication and reducing maintenance costs.
- Precision Performance: Manufactured to P0 tolerance class with a CN radial internal clearance, it delivers consistent and precise rotational performance.
