We have talked about the high-speed bearing, mainly SKF Bearing Dynamic Load Rating http://www.track-roller-bearing.com/ refers to the DN value greater than or equal to 1000000 (where D: bearing diameter, N: bearing speed) of the bearing.


Due to the high speed bearing speed is relatively high, is quite harsh industrial and mining, so for the adhesion and the working life of grease, have higher demand to working temperature.


High speed development in our country still near zero grease, high-speed bearing grease main application industry such as electronics, machine tool manufacturing, textile and chemical fiber industry. Because there is no related domestic products before, so, such as spindle lubrication, domestic generally adopt the method of thin oil lubrication before, although from the products unit price cost is lower than abroad use the grease, but due to supporting the use of tanks and other auxiliary equipment, there will be the problem such as oil leakage, so the comprehensive cost is not less than the use of grease. And other industries, at present the basic grease is directly imported abroad.


Abroad, mainly adopts high-speed bearing grease lubrication. Using the advantages of the grease is equipment structure more reasonable, simple and convenient maintenance, and low comprehensive cost. With the increasing number of domestic import equipment, the dosage of the domestic high-speed bearing grease is increased. In machine tool manufacturing, such as little giant, yida group, ince tektronix grease used in machine tool spindle.


Using high-speed bearing grease in the market now mainly compound barium base and compound lithium base. Most used products is Germany's KLUBER ISOFLEX NBU15 and ISOFLEX typical vmlinux.lds 18 SPECIAL A, respectively is barium compound and complex lithium based.


The performance of these products is very outstanding, of which the latter DN value reached $1200000, however, due to the direct import from abroad, so the price of these products is relatively expensive, so limiting their use range.


After a long time of research and development, the beneficial Tian Runshi Beijing chemical industry co., LTD succeeded in producing high-speed bearing grease RUBIA HTS high temperature grease, this product USES the barium compound thickeners, thickening special compound has a deployment.


From the point of product performance, after many clients of the actual use, use the effect is not inferior to the NBU15, even far better than NBU15 on temperature in industrial and mining, for the former working temperature is - 50-180 ℃, and NBU15 working temperature for - 40-130 ℃. But on the price, the former only 50-60% of that for the latter, economy is obvious.


With the development of domestic industry and the improving of the industrial technology and equipment, high-speed grease market also will be more and more big, hope to use our product to make contributions to the development of the domestic economy.
