1、 Storage of lubricating grease

Lubricating grease is a colloid. The structure of grease will be affected by various external factors during use and storage.

When stored in the warehouse, the temperature should not be higher than 35 ℃, and the packaging container should be sealed without leakage of water and foreign impurities.

After opening the barrel to take samples or products, do not leave holes in the packaging barrel. The grease surface after taking samples should be smoothed to prevent pits. Otherwise, the base oil will be squeezed by natural gravity and penetrate into the pits left by sampling, which will affect the quality of products.

2、 Usage of lubricating grease

1. The dosage should be appropriate

Excessive greasing will increase friction torque, temperature and grease consumption; If the amount of grease is too small, reliable lubrication will not be obtained and dry friction will occur. Generally speaking, the appropriate grease amount is 1/3 ~ 1/2 of the total void volume in the bearing.

Estimation formula: q=0.005 x D x B

Q -- filling amount, unit: G

D - outer diameter of bearing, unit: mm

B - bearing width, unit: mm

2. Do not mix greases of different brands

Since the thickener, base oil and additives used in the lubricating grease are different, the mixed use will cause the change of colloidal structure, which will increase the oil content, change the consistency and affect the mechanical stability.

3. Pay attention to grease change cycle and use process management

Pay attention to regularly fill and replace lubricating grease. When adding and replacing new grease, the waste grease shall be squeezed out until new grease is seen at the grease discharge port. The greasing process must be kept clean to prevent the mixing of mechanical impurities, dust and sand particles.
