1.Introduction：
The loss of the drive pipe wear in the drill pipe joints can’t be ignored during the processing of the deep mine, ultra-deep well, horizontal well and directional well. Using casing abrasion can effectively reduce the wear of drill pipe joints and lower the friction torque during the time of the drill pipe rotate. The both ends of the casing abrasion is conventional drill buckle, it can be easily individual or assembly used according to the requirement of well drilling.
2.Casing antichafe machine characteristics
.Adopting cemented carbide bearing, drilling fluid lubrication, long life, low friction coefficient.
.Made by high strength alloy steels, high strength, safe and reliable.
.Outside sliding sleeve is used low hardness alloy and antifriction composite.

- Q: I need regular manufacturers' agents (with authorized certificates and large scale agents)
- I am Nanjing Yi million strong bearing Co., Ltd. (Jiangyin Office)I am mainly responsible for regional sales in Jiangyin, Zhangjiagang, Jingjiang and so onWe are regular dealers. Here are our certificate of authorization.
- Q: A bearing assembly that can withstand greater torque (other requirements are not required and the axle is cantilevered)
- In addition, do not know in the operation process with no axial force, you can use two sets of spherical roller bearing.
- Q: What are the five types of bearings? Like F~G...? What else? Who knows?
- 6 categories: angular contact ball bearings, four point contact ball bearingsThe 7 category: tapered roller bearingsThe 8 Category: thrust ball bearings9 category: thrust roller bearingsPure hand-made, adopt landlord
- 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: 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: 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: What about the other workshops? Yes, I have a share in it. Which workshop is better in Changzhou?,
- Which shop is tired, hard work, see how you do, I hope you can help
- 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: What model is used more? What are the prospects for development? Does the price have an advantage?
- There are many manufacturers of this kind of bearings, mostly in ShandongShandong bearing price is very strong, quality is guaranteedInterested, contact information to see personal data
- 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.
