Sliding bearings are essential components in many mechanical systems, and proper lubrication is key to their long-term performance. Choosing the right type of grease and applying it correctly can significantly extend the life of your bearings and reduce maintenance costs. Here are some important tips for the correct application of sliding bearing grease: 1. **Choosing the Right Grease** - When the load is high and the speed is low, use a grease with a smaller penetration value for better performance. For high-speed applications, opt for a grease with good mechanical stability and lower base oil viscosity. - The dropping point of the grease should be at least 20–30°C higher than the operating temperature. Avoid exceeding the recommended temperature limits for prolonged operation. - In wet or humid environments, choose calcium-based, aluminum-based, or lithium-based greases that offer good water resistance. - Select a grease with strong adhesion properties to ensure it stays in place under various conditions. 2. **Grease Selection Based on Operating Conditions** - For loads below 1 MPa, with journal speeds under 1 m/s and maximum temperatures up to 75°C, use No. 3 calcium-based grease. - For loads between 1–6.5 MPa and journal speeds from 0.5–5 m/s, with a max temperature of 55°C, use No. 2 calcium-based grease. - For loads over 6.5 MPa and low journal speeds (under 0.5 m/s), with a max temp of 75°C, No. 3 calcium grease is suitable. - If the load is under 6.5 MPa, and the journal speed is between 0.5–5 m/s, with a max temp of 120°C, use No. 2 lithium grease. - For high-load applications (over 6.5 MPa) and low speeds, with a max temp of 110°C, consider calcium-sodium grease No. 2. - In humid conditions, with temps between 75–120°C, calcium-sodium grease is recommended. For lower temps (below 75°C), No. 3 calcium or aluminum grease can be used. At higher temps (110–120°C), lithium or thio-based greases are ideal. 3. **Grease Reapplication Intervals** - For occasional use (shaft speed <200 r/min), reapply every 5 days. For faster speeds (>200 r/min), apply every 3 days. - For continuous operation at temperatures below 40°C, apply daily if speed is <200 r/min, and once per shift if speed is higher. - For intermittent use at 40–100°C, apply once per shift at <200 r/min, and twice per shift at higher speeds. Proper lubrication not only reduces friction but also prevents wear and overheating, ensuring smooth and efficient operation of your machinery. Always follow manufacturer guidelines and adjust based on specific operating conditions. --- **Related Bearing Knowledge** Bearing classification, combined needle roller bearings, product density, manufacturing requirements, motor bearing overheating causes and solutions, linear bearing lubrication precautions, determining clearance of INA imported bearings, and more.
