W 626-2RS1/W64F Bearing Product Overview & Core Advantages
The W 626-2RS1/W64F is a single row deep groove ball bearing designed for high reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design with Solid Oil lubrication, providing a maintenance-free, long-service-life solution. This bearing is engineered to handle primarily radial loads and is suitable for a wide operating temperature range, making it an ideal choice for applications requiring durability and consistent performance.
W 626-2RS1/W64F Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Stainless Steel Bearing Series |
| 626 | Bearing size designation (6mm bore, 19mm OD, 6mm width) |
| 2RS1 | Contact seals on both sides for effective protection against contaminants |
| W64 | Solid Oil lubrication, a polymer matrix saturated with oil |
| F | Stainless Steel Machined Cage (from Chrome Steel material specification) |
W 626-2RS1/W64F Bearing Structural Features & Performance Benefits
The W 626-2RS1/W64F incorporates several key structural features that deliver distinct performance benefits. The single row deep groove raceway is precision-ground to ABEC 1 | ISO P0 tolerance, ensuring smooth operation and low noise. The contact seals (2RS1) provide superior exclusion of moisture and debris, significantly enhancing bearing life in harsh environments. The integration of Solid Oil (W64) lubrication eliminates the risk of oil leakage and offers a consistent lubricant supply, contributing to its maintenance-free characteristic. The use of a stainless steel machined cage (F) ensures high strength and dimensional stability, supporting reliable performance at the bearing's limiting speed. The combination of stainless steel rings and balls provides excellent resistance to corrosion, making it suitable for washdown or chemically aggressive atmospheres.
