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: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?: 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: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:In addition there is no other original bearing high speed bearing deposit in 50 seconds or more for the name?: If you're looking for speed, just like speed shoes.I suggest you go to 66club, take a look at all over the country, a forum for yo yo lovers, is currently more influential domestic university skating hobby league.

Q:Characteristics of cross roller bearings: 4, substantial savings in installation spaceThe size of the inner and outer ring cross roller bearing is miniature minimal, especially ultra-thin structure is small size close to the limit, and has high rigidity, so the most suitable for industrial robot joints or rotating parts, machining center of the rotary table, the robot rotating parts, precision rotary table, medical instrument IC, measuring equipment, manufacturing device widely used.5., high speed capacity6. reduce the shaft length and processing costs, thermal expansion leads to limited changes in geometric size7. 、 adopt nylon separator, low rotating inertia, low starting torque, easy to control angle division8., optimize pre tightening force, stiffness, guide roller running high accuracy9. carburizing steel provides excellent impact resistance and surface abrasion resistance

Q:where can I buy other GPS drilling accessories? I have some GPS rigs.: They have all rig accessories, very, very complete. You can call them 400

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:Why are the front fork bearings of the GY6 so difficult to buy, smaller than others?: Fork parts with multiple screws, different brands and models, there are differences between the screw size,

Q:What are the world bearing giants?: International bearing giants:Sweden: SKF (SKF group)Germany: INA/FAG (Schaeffler group)United States: TIMKEN (The Timken Company)Japan: NSK (Nske) NTN (NTN) KOYO (Guang Yang) NACHI (fujikoshi)NMB (Mei Beiya) THK (main line, unit FYH (bearing) main bearings etc.)

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

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.
