U.LUBE team on-site service case: Bearing lubrication improvement solution for dairy longitudinal sealing machine


某乳业厂的塑料包装生产线使用纵封机对冷饮成品包装成袋的开口处进行封口,纵封机设备经过优润(U.LUBE)团队现场调研发现一些问题。

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、 设备工况涉及高温,轴承处温度 130℃左右,出现润滑脂高温流失严重现象,目前使用某牌普通锂基润滑脂在 90-100℃左右就流失;

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、纵封机基本保持24小时运转,轴承疲劳程度高,在很多情况下是无油状态下运行,轴承磨损现象严重,导致频繁更换轴承;

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、同时加脂采用人工方式,频繁加脂增加人力成本,加脂效果不佳导致无油状态下运行;

3. At the same time, the grease is manually added, which increases human cost, poor greasing results and oil-free running.


4、在车间水汽环境中,目前使用的油脂防水性能比较差,容易导致润滑失效;

4. In the workshop water vapor environment, the current grease’s waterproof performance is relatively poor, easy lead to lubrication failure.

针对上述润滑问题,优润(U.LUBE)团队建议进行润滑改良,需要选择一款合适的轴承润滑脂如优润(U.LUBE)高性能合成润滑脂 ET PLEX 72S, 具有良好的高温耐受性与低温适用性。工作温度范围宽(-40℃~180℃),润滑寿命长。产品由特制复合锂稠化剂及全合成基础油制作而成,具有良好的耐温、耐化学稳定性、滴点高、抗磨性能好,并且具有良好的抗氧化能力及防锈能力,保障产品在高温、水及水蒸汽环境下均能保持良好的工作状态,满足以下几点要求。

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、使用耐高温达160℃的润滑脂,纵封机轴承的工作温度在130-140℃之间,使用高于最高温度点 20-30℃;

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、 要满足纵封机24小时工作状态,则应该使用耐高剪切力,四球载荷 200KG 以上具有良好润滑性,减缓轴承疲劳的工作状态,延长轴承使用寿命;

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、使用良好的长效性润滑剂,保持轴承良好的油膜,设备在有油状态下进行运转,同时改变以往频繁加油的情况,节省人工成本,提高效率。

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、针对车间水汽环境,则要求润滑剂必须有良好的抗水、防水性能,保证在车间潮湿环境下,轴承能保持24小时正常工作。

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.
