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:Feroform what bearing material, metal or nylon, or anything else?: A wear-resistant material, you can choose wear-resistant nylon material, it is recommended to use reinforced nylon 11, 12, 1212 long chain nylon series, such materials, good wear resistance, good toughness, high strength. If you need, you can contact me

Q:What are the five types of bearings? Like F~G...? What else? Who knows?: There are 10 kinds of rolling bearingsThe 0 category: deep groove ball bearings, double row deep groove ball bearingsThe 1 category: self-aligning ball bearings2 category: cylindrical roller bearings3 kinds of spherical roller bearings4 category: needle roller bearing5 category: spiral roller bearing

Q:I worked in my company bearing the main agent of Harbin SKF FAG NSK NTN the other bearing which have the quality in the first place absolutely genuine fake a lose ten: Tianjin riside Machinery Sales Co. ltd.. My company's main agent SKF NSK bearings

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:What are the advantages of ceramic ball bearings versus other bearings?: 1, insulation bearings;2, light weight, less heat, you can have higher working limit speed.

Q:Bearings into the sand, to dismantle the wheel, there are other ways?: If the bearings are not replaced, the bearings can be cleaned by kerosene, and then the grease is sealed again.

Q:Must the axle neck fit with the bearings? Is there anything else you can use? Or nothing?: Not necessarily, depends on the use of configuration, the shaft should generally be equipped with bearings, fixed shaft does not match the bearings..AskIs the rotating shaft, must use bearings? What else can I use in Dingxi?Chasing the answerThe support of the rotating shaft must be the bearing, and the bearing is no more than two kinds of rolling bearings and sliding bearings.

Q:A one-way bearing keyway hole can connect other parts of the shaft, driven by cylindrical rotation? How much speed can I expect?: You are not allowed to say this, with thick shaft, what types of bearings, preferably a drawing can be discussed, or that is not clear

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.

Q:How are the double seal bearings and other pattern bearings on the specifications and models?: Bearing type codeImports of bearings commonly used type code (refers to the beginning of the model numbers or letters, such as 6200, 6 is the beginning of deep groove ball bearings, NU, NJ for cylindrical roller bearings):Self-aligning ball bearing - 1;
