FAG imported bearings are precision components that require careful handling to ensure optimal performance. Even the most advanced bearings can fail if not used properly. Therefore, it's essential to follow correct application methods when working with FAG bearings. Here are some key points to consider: 1. **Maintain a Clean Environment** Dust and debris, even invisible to the naked eye, can significantly affect the performance of FAG bearings. Always keep the surrounding area clean to prevent contamination. 2. **Handle with Care** Avoid applying excessive force or impact during installation or operation. This can cause scratches, dents, or even cracks in the bearing, leading to premature failure. 3. **Use Proper Tools** Never substitute tools or parts. Always use the right equipment and materials for installation and maintenance to avoid damage. 4. **Prevent Rust** Keep your hands clean when handling FAG bearings. Sweat from your fingers can lead to rust. It's recommended to wear gloves when touching the bearings. **FAG Bearing Installation Methods** Many users are familiar with FAG bearings but may not know the proper installation techniques. The way you install a bearing can greatly affect its accuracy, lifespan, and overall performance. Follow these guidelines for proper installation: a. **Press Fit Installation** When the inner ring is tightly fitted to the shaft and the outer ring is loosely fitted to the housing, press the bearing onto the shaft using a press. Then, insert the shaft into the housing along with the bearing. To protect the bearing, use a soft metal sleeve (such as copper or mild steel) when pressing on the inner ring. The inner diameter of the sleeve should be slightly larger than the journal, while the outer diameter should be slightly smaller than the bearing’s inner ring. b. **Outer Ring Press Fit** If the outer ring is tightly fitted to the housing and the inner ring is loosely fitted to the shaft, first press the bearing into the housing. If both the inner and outer rings are tightly fitted, press them together into the shaft and housing. Ensure the installation sleeve is designed to support both the inner and outer rings effectively. **Lubrication Tips** It's best to open the bearing cover and add lubricant when installing a new FAG bearing. However, molybdenum disulfide lithium-based grease is highly recommended due to its excellent high-temperature resistance and wear protection. Calcium-based grease is less suitable for high-temperature applications. When replacing the original grease, ensure the bearing temperature does not exceed 70°C. For high-speed bearings, regular re-lubrication is necessary. In gearboxes, the temperature should not exceed 60°C, and for pump bearings, it should remain below 65°C.
