How to use high temperature grease properly

1. The amount of smoothing should be appropriate

If the amount of fat is too large, the frictional torque will increase, the temperature will rise, and the amount of fat will increase; while if the amount of fat is too small, it will not be possible to obtain a smooth and reliable dry friction. Generally speaking, the suitable amount of grease is 1/3 ~ 1/2 of the total void volume in the bearing. However, depending on the details, sometimes the bearing edges should be greased to smooth the cavity.

2. Pay attention to prevent different types, brands and mix of old and new grease

Prevent the use of grease containers and things, otherwise, it will have a negative impact on the drop point of fat, increase in penetration and decrease in mechanical stability.

3. Pay attention to the replacement of new grease

Because the type and quality of grease are constantly being improved and changed, old equipment should be tested before being used with new grease before trial use before being officially used; when replacing new grease, first remove waste grease and clean parts. clean. When replenishing grease, squeeze out waste grease and stop when new grease is seen at the grease outlet.

4. Pay attention to the management of grease filling process

Before collecting and filling the grease, pay close attention to the cleanliness of the container and things. The grease supply port on the equipment should be cleaned beforehand to prevent the mixing of mechanical impurities, dust and grit.

5. Pay attention to timely replacement of seasonal fats

For example, the temperature difference between winter and summer plums in the environment where the equipment is located changes greatly. If the winter fat is used in summer, the result may be reversed.

6. Pay attention to changing grease regularly

The time of adding and changing the grease should be determined according to the detailed use situation, which must ensure a smooth and reliable and not cause the waste of grease.

Pay attention to storage method

Do not use wooden or paper containers to pack grease to prevent oil loss and hardening, mixing with moisture or contamination, and storing in a cool, dry place.
