In NACHI

The two NACHI Co., LTD from since the company was established in 1928 has been committed to develop mechanical technology. Now that the company has grown as a comprehensive mechanical and electronic manufacturer to a wide range of industries, provide foundation equipments and components. Grease choice

According to the working temperature selection, main index should grease is dropping point, oxidation stability and low temperature performance, dropping point generally can be used to evaluate high temperature performance, sliding bearing mechanical injury refers to the alloy surface bearing the cleft in different degree, serious when in contact surface of metal stripping and a massive happened disorderly scratch; Normally, surface damage and ablation phenomenon also exist. Cause bearing mechanical damage is the main reason of the bearing surface oil film or difficulty in forming the oil film were severely damaged. Bearing the practical work should be less than 10 drop point temperature 20 ℃. The use of synthetic grease should be below the dropping point temperature of 20 to 30 ℃. According to bearing load selection of heavy load, grease the needle into the degrees of voting small grease. Except in high-pressure work outside the degree small needle but higher oil film strength and extreme pressure properties. According to the environment condition selecting greases, calcium and manufactured not easily soluble in water, suitable for dry and moisture less environment.
