Proper lubrication is essential for the smooth operation and longevity of mechanical systems, especially for NSK bearings. A significant portion of mechanical failures or premature wear is linked to poor lubrication practices. Ensuring proper oil handling can prevent damage such as scratching or welding between moving parts like bearings and gears. It also helps reduce friction, minimize wear, and improve overall equipment efficiency. Here are some key points to consider when managing oil film for NSK bearings: 1. **Professional Lubrication Management**: Assign trained personnel to handle lubrication tasks. Develop a structured lubrication management system and conduct regular training to ensure all staff understand best practices. 2. **Maintain Proper Oil Levels**: Ensure the oil tank has an adequate capacity and maintain the correct oil level. Regularly top up the oil and check for air bubbles, sediment, and temperature conditions within the system. 3. **Oil Sampling and Testing**: Perform regular oil sampling and analysis. Check for changes in color, viscosity, water content, and contamination levels. If impurities exceed 0.1%, it can significantly increase wear. If contamination exceeds 0.5%, it becomes a serious risk. 4. **Data Analysis and Predictive Maintenance**: Keep detailed records of each test and use this data to predict potential issues. Implement preventive measures and ensure that oil levels, quality, temperature, and pressure are monitored and controlled effectively. 5. **Prevent Contamination**: - **Procurement and Storage**: Maintain strict procedures for oil storage, labeling, and disposal. Different types of oil should be clearly marked and separated to avoid mixing. - **Storage Conditions**: Store oil in clean, sealed containers away from light, heat, and moisture. Ensure warehouses are well-ventilated and equipped with fire safety features. - **Inspection Standards**: Regularly check oil for viscosity, water content, demulsibility, and contamination. Impurities should not exceed 0.01%. - **Tank Maintenance**: Keep the oil tank sealed and install high-quality filters (100 mesh or finer). Drain the tank regularly and avoid using fiber cloths to wipe the tank surface. - **Filter Replacement**: When replacing filters, drain the oil from the filter cartridge and avoid contaminating downstream piping. - **Oil Change Schedule**: Replace oil based on its condition—color, viscosity, moisture, and pollution level. 6. **Initial Use of New Oil**: When introducing new oil for the first time, ensure the entire existing lubrication system is thoroughly cleaned. Follow these steps: - Compare the physical and chemical properties of the new oil with those of the manufacturer’s products. - Involve skilled personnel to analyze oil performance data and ensure correct application. - Conduct mixing tests between new and used oil to assess compatibility. **Related Bearing Knowledge** - Repair of hydrostatic bearings in grinding machines - Advances in super-finishing technology for bearing rings - Development of high-speed angular contact ball bearings - Analysis of TIMKEN bearing disassembly performance This article is sourced from China Bearing Network.
