6021/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 6021 | Standard single row deep groove ball bearing with 105mm bore, 160mm OD, 26mm width. |
| Lubrication System | W64 | Indicates the bearing is pre-lubricated with Soild Oil, a polymer matrix saturated with lubricant, offering superior retention and contamination resistance compared to traditional grease. |
6021/W64 Bearing Structural Features & Performance Benefits
- High Load Capacity & Durability: Manufactured from chrome steel for both rings, balls, and cage, this bearing provides high strength and resistance to wear. With a radial dynamic load rating of 16,254 lbf and a static load rating of 14,792 lbf, it is built to withstand significant stresses.
- Maintenance-Free Operation: The integrated Soild Oil lubrication eliminates the need for re-lubrication, reducing maintenance costs and preventing lubricant leakage. This is ideal for sealed-for-life applications or hard-to-reach locations.
- Standard Precision & Clearance: The ABEC 1 (ISO P0) tolerance class and standard CN radial internal clearance ensure consistent, reliable performance for a vast majority of industrial applications, providing smooth operation and extended service life.
- Broad Temperature Range: Operates effectively within a temperature range of -30°C to 120°C, making it suitable for various environmental conditions.
