W 626 Bearing Product Overview & Core Advantages
The W 626 is a metric single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This bearing is designed to primarily accommodate radial loads and is characterized by its compact design with a 6 mm bore, 19 mm outside diameter, and 6 mm width. Its open seal type and P0 tolerance class make it a versatile and cost-effective solution for a wide range of industrial applications demanding consistent operation.
W 626 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Indicates a stainless steel construction for the bearing rings and balls. |
| 626 | Specifies the bearing size series, denoting a 6 mm bore, 19 mm OD, and 6 mm width. |
| (No Seal Suffix) | The absence of a seal suffix (e.g., 2Z, RS) designates an open bearing, allowing for higher limiting speeds and custom lubrication options. |
W 626 Bearing Structural Features & Performance Benefits
All-Stainless Steel Construction: The use of stainless steel for the rings, balls, and cage provides superior corrosion resistance, making the W 626 ideal for applications exposed to moisture, chemicals, or washdown environments.
Radial Load Capacity: The single row deep groove design is optimized to efficiently support radial dynamic loads up to 344 lbf, ensuring stable operation.
High-Speed Capability: The open design and precision manufacturing contribute to a high limiting speed of 56,000 rpm, suitable for demanding high-velocity applications.
Precision & Versatility: Manufactured to P0 tolerance class with a standard CN radial internal clearance, this bearing offers reliable performance for general-purpose use. The open structure allows for flexibility in lubrication based on specific operational needs.
W 626 Bearing Typical Application Areas
The W 626 ball bearing is widely used in various precision instruments and machinery, including:
- Small electric motors and gearboxes
- Medical and dental equipment
- Food processing machinery
- Optical and encoder devices
- Office automation equipment
