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:Excuse me, what about the units that sell bearings, what else do they sell? Thirty
If you do not say the product; if you do customers, I think everything can be done, as long as the customer has potential demand products, as long as there is profit, you are still selling what products?.
Q:Bearing fever.
Possible in the middle. There may be other problems. You can try with them. Excellent
Q:How can the rod joint bearings be connected with other parts?
1. is the standard parts. The national standard is 2. GB/T 304.92008. 3., I have the latest electronic version of the national standard. If necessary, please contact me at the station and inform me of the email address. I will send it to you.
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: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:Bearings into the sand, to dismantle the wheel, there are other ways?
But there will be some small noise when rotating, and it is better to replace a new one.
Q:What are the world bearing giants?
Domestic comparison of large-scale bearing companies, mainly in the following:HRB (Kazakhstan axis) LYC (Luozhou) ZWZ (Wa Zhou) axis Institute of Technology (ZYS)Northwest axis universal bearings, human bearings, Tianma bearings, Xiangyang bearings, Jinxi axle, Longxi bearings, and so onAt present, about eight or nine listed Bearing Enterprises
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:Is there any FAG or other imported brand bearings in Jiangyin?
Hello, I do import bearings, have authorization letter, customs declaration, certificate of origin and other relevant informationContact personal data
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
