In modern spray production lines, robot joints and bearings are "core components" that operate at high speed around the clock. Especially in painting workshops of industries such as automobile and home appliances, spray robots not only have to face high temperatures but also withstand "numerous tests" of chemical corrosion from paints and solvents. Choosing the right lubricating grease is crucial.
Common lubrication pain points during the use of spray robots are as follows:
Paint contamination: Coating particles generated during the spraying process easily invade lubrication points, leading to a decline in the performance of lubricating grease. If not cleaned and replenished in time, equipment wear will intensify, and maintenance costs will rise sharply.
High-temperature oxidation: The temperature in the drying process is high, and long-term operation will accelerate the oxidation and coking of lubricating grease, resulting in lubrication failure. Usually, it needs to be replaced every 500 hours.
Poor dynamic adaptability: The rotating cup rotates at high speed with frequent changes in speed. If the lubricating grease has insufficient shear stability, it will be thrown off by centrifugal force, and the risk of oil film rupture is high.
Baoxing suggests that when choosing lubricating grease for spray robots, the grease needs to meet the following requirements at the same time:
✅ High temperature resistance: It does not decompose when in long-term contact with spraying heat sources. Polyurea-based lubricating grease (dropping point > 200℃) or fluorine-based lubricating grease can easily cope with this.
✅ Resistance to chemical corrosion: It can resist the erosion of paints and solvents, extending the lubrication life.
✅ High shear stability: Maintain the integrity of the oil film when the rotating cup is running at high speed to avoid lubrication failure.
Baoxing Lubricants recommends establishing a regular inspection and grease replenishment system according to the actual working conditions of the equipment. With special lubricating grease that is resistant to high temperature, chemical corrosion, and has high shear stability, spray robots can always maintain smooth operation, reduce downtime and maintenance costs, and make the production line more efficient and secure.
