Product Description:

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:SKF bearing samples provide full set of SKF bearing samples, and other brand samples
Bearing samples directly to the company, want it to send ah ~ we are all so ~ even if I have, how to give you?
Q:22318CA are there any other bearings that can be used instead?
You use 22318cc. The maintainer is different. Different structure. Good
Q:Motor vibration is too large, in addition to bearing problems, there are other reasons?
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: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:Is there any difference between plain bearings and other bearings?
Bearings are nothing more than sliding bearings and rolling bearings, sliding bearings without moving coil, a shaft directly contact the shaft, the shaft will be worn, rolling bearings can roll the moving coil, and the shaft is connected, the shaft will not wear.
Q:Must the axle neck fit with the bearings? Is there anything else you can use? Or nothing?
Must the axle neck fit with the bearing? - yes. In general, when using radial bearings, the shaft neck tolerance is K6, and the surface roughness is 1.6.
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:In the customs tariff classification,
Sliding bearing partsThe bearing is sliding bearing and shaft parts, very smooth, generally made of bronze, anti friction alloy wear-resistant material, in particular, can be made of wood, plastic or rubber.
Q:Bearings radial, in addition to the location of contact with the box, there is no other way?
10, to prevent the bearing in axial load axial movement, bearings on the shaft and outside the Nanning hole are applied axial positioning device. Bearings on the shaft and the selection of the location of the shell depends on the size and direction of the load on the shaft, the speed of the bearing, the type of bearing, the position of the bearing on the shaft, etc.. The higher the axial load, the higher the bearing speed, the more reliable the axial alignment. For different types of bearings, axial positioning should also be different. Such as diagonal contact ball bearings and tapered roller bearings, shoulder and shell holes can be used to shoulder one-way support, without the use of special positioning device, the ring in the axial movement can be supported by the bearing itself. As a fixed support radial bearing, the inner and outer rings are fixed on the left support in the axial direction. As a traveling support that needs to compensate for the thermal elongation of the shaft, if a separable bearing is not installed, only one of the rings needs to be fixed, and the traveling ring is not fixed. Separate bearings, such as short cylindrical roller bearings and needle roller bearings, are installed in the traveling support, and all two rings need to be fixed. Bearing bearing ring used to positioning method is described as follows: 1. the bearing inner ring mounted on the shaft bearing inner ring, generally by the shaft in a fixed bearing position, and the other side with nuts and washers or spring retainer ring fixed.
Q:In the end is one-way bearings skidding or other reasons, the following reasonable interpretation of the phenomenon
The rear hand engine is not completely sealed, there will be a small part of the fuel into the one-way bearing in the fuel methanol has the function of cleaning, the equivalent of the one-way bearing lubricating oil on the wash, so temporarily good. But because of the one-way bearing itself has been unable to hold the start shaft (possibly starting shaft wear), so palliatives
