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: 22318CA are there any other bearings that can be used instead?
You use 22318cc. The maintainer is different. Different structure. Good
Q: How can the rod joint bearings be connected with other parts?
Threaded, rod end joint bearings with internal and external thread points, used in different workpieces. The screw thread is generally used on the fixed shaft, and then the rotating shaft passes through the fish eye bore to form a movable joint part.There is no specific picture, you can refer to the network of rod end joint bearing sample diagram, imagine.
Q: FAG bidirectional thrust angular contact bearing 234416M.SP can be replaced by other manufacturers?
Hangzhou Yakang told youNSK =80TAC20X+LNtn=562016SKF=234416BNACHI=80TAD120
Q: A winter hand is out of the question, always pull the beginning of a circle when no problem, after feeling a little strength are not, pay attention to the following 2: 1, the legend of the hand is slipping should take a one-way bearing cleaning, I remove the bubble in alcohol and with ultrasonic cleaner washing, the result is really good for a moment, the next is not good; also for the one-way bearing, when the hammer is likely to change in the same phenomenon. 2, this is a method I find, is the first at home to the engine oil pump, the pump to the obvious rich and even a little bit when misfire, hand is good, get out after the fire down soon start pouring fuel, normally is not a one-way bearing can not enter fuel? Late into the fuel hand puller is obviously not slip like a long time don't see is what reason, solution!
Is the quality of bearings, the size is not standard, because the axis tolerances are limited, resulting in a loose tight. Replace the bearings of better quality.In principle, the general transition fit, one-way needle, this structure is too simple, and the accuracy is not high, the domestic small factory product quality is not stable.A one-way bearing is a type of bearing that can be turned freely in one direction and locked in another direction. One-way bearings, also known as overrunning clutch, but according to different industries, the role of different naming.
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: 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: I feel different from other factories, ah, there is no pungent smell!
Yes, they have a business manager named Feng Dawei. The business ability is very strong, you can find him
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: How are the double seal bearings and other pattern bearings on the specifications and models?
Angular contact ball bearings - 7;Cylindrical roller bearings - N;Needle roller bearing - NA;
Q: What is the cause of a large bearing vibration of a turbine and other bearings?
If the shock bearing is not new, there may be the bearing itself, then change it. If the new bearings and bearings are genuine, I suggest you detect dynamic balance
