Product Description:

1.PDC thrust bearing is widely used in downhole dynamic drilling tools, it is with high hardness and longer life charateristics. It can be in operation at super high temperature (currently the highest temperature is 233℃)and it can hold higher axial load. One pair PDC thrust bearing includes upper ring and bottom ring,one piece PDC thrust bearing includes two part: tungsten carbide ring and PDC compact.PDC material friction coefficient is very low so that it can not be affected by chemical material.


2.PDC thrust bearing is made with standard brazing technology, its compact surface hardness is very high, the contact surface flatness of PDC compact is very low and difficult to manufacture. Few factories in China could overcome this problem.


3.With many times improvement Research and development, we use more advanced welding and grinding technology, has overcome the flatness problem of PDC compact contact surface, make the contact surface flatness less than 0.02mm so that strongly improved PDC thrust bearing service life. Our technology for manufacturing PDC thrust bearing has reached the international advanced level in the industry.

Q:I worked in my company bearing the main agent of Harbin SKF FAG NSK NTN the other bearing which have the quality in the first place absolutely genuine fake a lose ten
What is your department, I also do bearings, practitioners have been 20 years, I hope to exchange. Please leave a contact information.
Q:Why are the front fork bearings of the GY6 so difficult to buy, smaller than others?
if the big nut steering column, in the absence of special sleeve case, can use spanner or hook wrench assembly.
Q:Are there any differences between bearings used on fans and other ordinary bearings?
the fan usually has two ends adjustable heart or one end of the cylinder with diagonal contact at one end.
Q:Motor vibration is too large, in addition to bearing problems, there are other reasons?
1, first of all, do not know what you are using bearings, I do not know if you choose the bearings there is no problem.2, secondly, if you choose the correct bearings, shaft and bearing installation is not a problem? Preload is not enough? Loosely matched?3, it is best to know the motor power, you choose the type of bearing. In this way, we will give you the correct answer to the question ah.
Q:The car separation bearing is broken, isn't it? What's the cause of the other broken bearings?
Judging the quality of the separation of bearings: step down the clutch pedal to half linkage position, and then make a noise, you can judge the separation of bearing damage
Q:What's the bearing fillet of the 7003C? Do other bearings have the same fillet?
The other bearings don't have the same fillet, and the bigger the bearing, the bigger the fillet.
Q:What are the five types of bearings? Like F~G...? What else? Who knows?
There are 10 kinds of rolling bearingsThe 0 category: deep groove ball bearings, double row deep groove ball bearingsThe 1 category: self-aligning ball bearings2 category: cylindrical roller bearings3 kinds of spherical roller bearings4 category: needle roller bearing5 category: spiral roller bearing
Q:In addition to NSK and KOYO, what are the other four major bearing producers in Japan?
NSK in Japan bearing is the largest share of the domestic market after the Swedish SKF, NTN and Koyo other than NSK.
Q:Characteristics of cross roller bearings
Cross roller bearings, with the inner and outer ring divided into, roller and interval retainer, and cross roller collar fixed together, separated from each other to prevent the installation of cross roller collar simple operation. Because roller cross arrangement, so only 1 sets of cross roller collar can withstand various direction load, compared with the traditional model, increase the rigidity of 3~4 times. At the same time, because the cross roller bearing inner ring or outer ring is a two division structure, the bearing clearance can be adjusted, even if the preload is applied, high precision rotary movement can be achieved.1, with excellent rotation accuracyThe internal structure of cross roller bearings is made of 90 degrees vertical cross arrangement of rollers,The roller is provided with an interval retainer or an isolating block, which prevents the tilting of the roller and the grinding between the rollers. In addition, the phenomenon of side contact or locking of the roller can not occur; at the same time, because the inner and outer ring is a segmented structure, the clearance can be adjusted, and even high-precision rotation can be obtained even if the preload is applied.2. Simplify the operation and installationThe outer ring or inner ring divided into 2 parts is fixed together after the roller and retainer are mounted, so the installation is very simple.3, bear larger axial and radial loadBecause the rollers are arranged perpendicularly to each other on the rolling surface of the V groove on a 90 degree angle.
Q:In engineering practice, for needle roller bearings, usually axial positioning is the same as other bearings?
Needle bearing features are axial can not bear the load, so the operation of the axial direction of the bearing no force, radial installation slightly tight can be, the axial need not limit
