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:How can I solve this problem? FifteenOur motor is used in the submersible pump, the speed in the 3000 turn around /min, now excessive vibration occurs, or for a better quality of the bearing vibration is too large, please professional prawns, this is what reason? How to solve?
- The rotor balance is poorThe impeller of the water pump doesn't balance properlyThe rotor is not in the center positionThe impeller is not in the centerLoose partsResonance generationForeign bodies on the surface of the impellerIf it is three-phase, it may be unbalancedThere may be foreign material in the outlet pipe, resulting in a vortex street.
- Q:What does 7 represent? What does the rest represent? If 7 is changed into other numbers, what does it represent?
- B stands for angular contact bearings with an angle of 40 degreesE stands for internal design and has been optimizedCB represents the universal set of single row angular contact bearings in the face, back to back, clearance for ordinary group
- Q:I feel different from other factories, ah, there is no pungent smell!
- You go to Harbin axis Ji'nan company to ask, they are the factory's direct center, can solve your problem
- Q:22318CA are there any other bearings that can be used instead?
- If you think the 22318 speed is not high enough, you can get a 2318 instead. But! 2318 of the load is not 22318 high, must confirm the load before changing
- Q:Feroform what bearing material, metal or nylon, or anything else?
- A wear-resistant material, you can choose wear-resistant nylon material, it is recommended to use reinforced nylon 11, 12, 1212 long chain nylon series, such materials, good wear resistance, good toughness, high strength. If you need, you can contact me
- Q:Why are the front fork bearings of the GY6 so difficult to buy, smaller than others?
- GY6 pedal motorcycle, in addition to the crankshaft on the right side of the starting driven gear, there is a reverse Taiwan screws, other screws include the front fork, each screw is thread.
- Q:SKF bearing samples provide full set of SKF bearing samples, and other brand samples
- Do you have any? I can cash in Chinese paper samples
- Q:Are there any differences between bearings used on fans and other ordinary bearings?
- If the model is the same, it makes no difference.From the point of view of the category, there are more taper and more heart in the gearbox; the fan usually has two ends adjustable heart or one end of the cylinder with diagonal contact at one end.
- Q:FAG bidirectional thrust angular contact bearing 234416M.SP can be replaced by other manufacturers?
- Japan NSK Code: 80TAC20XLJapan NTN code name: 562016SKF code name: 234416TN9/SPDomestic HRB Code: new code name: 234416. Old code name: 2268116
- Q:In bearings, why are the flanges connecting the upper and lower cases higher than those of the other bearings?
- If it is understood as the reducer, the upper and lower box connecting the flange (bearing box outside the prominent part), the reason is to prevent the bearings in operation, gear and box friction, damage box, reduce gear life.
