U.LUBE team on-site service case: Bearing lubrication improvement solution for dairy longitudinal sealing machine
The plastic packaging line of the dairy factory uses a longitudinal sealing machine to seal the packaging bag for cold drink finished product.But after on-site research, our U.LUBE team found there’s some existing problems as followed:
1、The equipment working condition involves high temperature, the temperature at the bearing is about 130℃, there is a serious loss of grease at 90-100℃ when using a brand of ordinary lithium grease.
2. The longitudinal sealing machine basically keeps running 24 hours, the bearing fatigue is high, in many cases it runs without oil, which results more serious wear on bearing, therefore, it brings frequent replacement of bearing.
3. At the same time, the grease is manually added, which increases human cost, poor greasing results and oil-free running.
4. In the workshop water vapor environment, the current grease’s waterproof performance is relatively poor, easy lead to lubrication failure.
Longitudinal sealing machine lubrication improvement
For the above lubrication problems, the U.LUBE team recommends a suitable bearing grease such as U.LUBE high performance synthetic grease ET PLEX 72S, which has excellent high temperature resistance and low temperature applicability. It has a wide operating temperature range (-40°C to 180°C) and long lubrication life. The product is made of special complex lithium thickener and full synthetic base oil, which has good temperature resistance, chemical stability, high dropping point, good anti-wear performance, good anti-oxidation ability and anti-rust ability, and ensures good working condition under high temperature, water and vapor environment. It also meets following requirements:
1. Use grease with high temperature resistance up to 160℃, the working temperature of longitudinal sealing machine bearing is between 130-140℃, the grease’s working temperature should be 20-30℃ above the maximum temperature point.
2. In order to meet the 24-hour working condition of the longitudinal sealing machine, grease with high shear force should be used, and its four ball load is more than 200KG with good lubrication, which can slow down bearing fatigue and extend the service life of bearings.
3. Using a long-lasting lubricant to keep good oil film and lubrication of the bearing can change the situation of frequent refueling, save labor cost and improve efficiency.
4、For the workshop water vapor environment, it requires the lubricant must have good water resistance and waterproof performance to ensure the bearings can keep working normally for 24 hours under the humid environment in the workshop.
