W 617/4 X Bearing Product Overview & Core Advantages
The W 617/4 X is a metric single row deep groove ball bearing designed for high-performance applications requiring compact dimensions and reliable operation. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its open design allows for versatile lubrication options and facilitates high-speed operation, making it an ideal choice for applications demanding precision and durability in a minimal space envelope.
Model Code In-Depth Explanation
| Code Segment | Technical Meaning |
|---|---|
| W | Indicates a stainless steel deep groove ball bearing. |
| 617/4 | Specifies the bearing series (617) and the bore diameter of 4 mm. |
| X | Denotes a special internal design or clearance, often linked to the CN radial internal clearance in this context. |
Note: The "Open" seal type and "None" for lubrication are inherent to the base model and are not represented by a suffix in this code.
W 617/4 X Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single row construction with a 2 mm width provides a space-saving solution without compromising structural integrity. All components, including rings, balls, and cage, are made from stainless steel, ensuring high corrosion resistance and operational reliability in harsh environments.
High-Speed Capability: The open design, combined with a stainless steel cage, minimizes friction and allows for a high limiting speed of 90,000 rpm. This makes it suitable for high-speed spindles and miniature motors.
Radial Load Capacity: Engineered to handle primarily radial loads, with a dynamic load rating of 51 lbf and a static load rating of 16 lbf. The standard CN radial internal clearance ensures optimal performance under normal operating conditions.
Precision & Compliance: Manufactured to P0 tolerance class with tight dimensional tolerances, guaranteeing consistent performance. It is compliant with ROHS and REACH regulations, making it suitable for use in environmentally sensitive and regulated industries.
W 617/4 X Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and small measuring instruments.
- High-Speed Miniature Motors: Spindles in small drones, RC models, and micro-motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Food Processing & Pharmaceutical Machinery: Where corrosion resistance and cleanability are paramount.
