The high-speed bearings we talked about; the first thing is the bearing with a DN value greater than or equal to 1000000 (D: bearing diameter; N: bearing speed).
Because the speed of high-speed bearings is relatively high; industrial and mining are more demanding; so the adhesion to smooth grease and the number of operating life; operating temperature has a higher demand.
The development of high-speed smooth grease in China is still almost zero; the main occupations of high-speed bearing grease are electronics, machine tool manufacturing, textile and chemical fiber occupation, etc. There have been no related products in China; therefore, the smoothness of the machine tool spindle; The method of selecting thin oil is smooth; although the price per unit of the product is lower than the high-speed smooth grease used in foreign countries; but it is necessary to use auxiliary equipment such as fuel tank; it also presents problems such as leakage of oil; therefore, it is not smoother to summarize the cost. Low fat.
And other occupations; the currently selected smooth fat is imported directly from abroad.
In foreign countries, the first choice is high-speed bearing grease smooth. The advantage of using smooth grease is that the layout of the equipment is more reasonable; the equipment protection is simple and convenient; and; the induction cost is lower. More and more domestic imported equipment; domestic high-speed bearings The amount of fat is also increasing. In the machine tool manufacturing industry; such as Xiaoweiren, Yida Riping Group, Instek, etc. are using the grease smooth machine tool spindle.
The high-speed bearing grease used in shopping malls is mainly composed of composite bismuth base and composite lithium base. The most used products are ISOFLEX NBU15 and ISOFLEX LDS 18 SPECIAL A of KLUBER, Germany; they are composite bismuth and lithium complex.
The functions of these products are very good; the latter has a DN value of 1,200,000; however; since they are imported directly from abroad; the prices of these products are relatively expensive; therefore, their scope of application is constrained.
Through long-term development; Yitian Runshi Beijing Chemical Co., Ltd. successfully produced high-speed bearing grease RUBIA HTS high-temperature high-speed smooth grease; this product uses composite bismuth thickener; thickening special composition has been distributed.
From the point of view of product function; through the practical use of many customers; the effect is no worse than NBU15; even in temperature industrial and mining is far better than NBU15; because the former operating temperature is -50 180 ° C; and NBU15 operating temperature is -40 130 ° C. But in terms of price; the former is only 50-60% of the latter; the economy is clear.
With the development of domestic basic industries and the continuous promotion of industrial technology and equipment; shopping malls with high-speed smooth grease will become larger and larger; expect to use our products to contribute to the development of the domestic economy!

Aquarium Underwater Lighting

To create the ideal environment for your fish, proper and regulated light in the aquariums is of premier importance. Fish thrive under proper light but in relative moderation.This means that considerable thought and a modest investment will be required to keep your tank well lit, both for your pleasure as well as the fish.


The light in an average home is generally not enough for the fish living in an aquarium. Living all day and all night in that environment will not be conducive to the fish`s health or even their temperament. Like humans, fish thrive in a warm and pleasant atmosphere. Statistics definitely prove that fish living in a well lit aquarium certainly live longer and appear to be more energetic which must cause us to assume that they are happy.
