1.Introduction：
Directional connector has two forms, directional bending joints and directional direct head. It is one of main tools in the making of power drilling tools. Power drilling tools give the drill continuous lateral force to make the drills continuously incise borehole wall under the effect of directional connector, and finally can be completed the curve of the well bore track.

- 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:Feroform what bearing material, metal or nylon, or anything else?
- It's made of toughened and wear-resistant nylon, which is more high-grade. As bearings, there are generally PA66+30GF/CF, PA66+PTFE+GF/CF, PA66+, molybdenum disulfide, of which the most cost-effective is PA66+ molybdenum disulfide. Our company has production, and if necessary, you can contact me.
- 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:Bearings radial, in addition to the location of contact with the box, there is no other way?
- 2. the outer ring of the bearing outer ring of the bearing outer ring is arranged in the outer hole of the outer shell, and the inner side of the outer hole of the outer shell generally has the position of the shoulder fixed bearing, and the other side is positioned with an end cover, a thread ring and a hole, and an elastic ring ring. (1) the end cover positioning end cover is used for all kinds of radial bearings and angular contact bearings. When the bearing speed is higher and the axial load is larger. The end cover is positioned and pressed with a screw to compress the outer ring of the bearing, and the end cover can also be made into a labyrinth sealing device. (2) thread ring bearing high positioning speed, axial load, not suitable for use under the condition of end cap positioning, available thread ring positioning radial bearing and thrust bearing, this can be used to adjust the axial clearance of the bearing. (3) the axial position of the elastic ring positioning method is small, the installation and disassembly are convenient, the manufacture is simple, and the utility model is suitable for bearing smaller axial load places. An adjusting ring is added between the bearing and the spring, so that the axial position can be adjusted conveniently. (4) the deep groove ball bearing with a stopping groove on the outer ring of the bearing can be fixed by the retaining ring. This type shall be used when the inside of the housing hole cannot be machined because of the condition limit, or the part must be reduced in outline size
- 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:Is there any difference between plain bearings and other bearings?
- The biggest difference between the sliding bearings is linear motion, and the other bearings do circular motion.
- 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.).The Swedish SKF company was founded in 1907, in the rolling bearing sector is the world's leading supplier, experience and professional skills of the bearing and bearing unit, seal, lubrication system, electromechanical integration and service five platform with its more than 100 years, SKF has become a knowledge-based company. In 2007, SKF sold more than SEK 58 billion 500 million.The German Schaeffler Group owns three brands: INA, FAG and LuK, are rolling bearings and linear motion products leading manufacturer, supplier of automotive industry is also well-known engine, gearbox, chassis applications of high precision products and systems. The group represents a high degree of customer focus, exceptional innovation, and highest quality standards. The group has about 74000 employees worldwide, with more than 180 branches in more than 50 countries, with sales of about 10 billion 700 million euros in 2011. This makes the Schaeffler group one of the largest family business groups in Germany and europe.The Timken Company was founded in 1922, operating range: aviation, construction, medical, heavy industry, machine tools, consumer goods, energy and industrial equipment. Wuxi solid Chinese sales agent TIMKENTIMKEN bearing inner ring bearings Co. Ltd., TIMKEN bearing outer ring, roller bearing TIMKEN, TIMKEN bearings, TIMKEN bearings accessories, TIMKEN bearing, TIMKEN metric 3000 series. The The Timken Company set up eight technical centers
- Q:Machine specific, please describe the specific points
- Outer spherical bearings: spherical roller bearings with wide outer rings and outer rings with locking elements. Mainly for simple housingsLinear motion bearing: two roller, in the direction of rolling has relatively linear motion of rolling bearingsBall bearing: the rolling body is the rolling bearing of the ballDeep groove ball bearings: ball bearing continuous groove of each ring has a cross section of the ball about three weeks of the raceway, suitable for precision instruments, low noise motor, automobile, motorcycle and general machinery, is the most widely used type of bearings in machinery industry. Simple structure, use and maintenance convenient. Mainly used to bear radial load, also can withstand certain axial load, when the bearing radial clearance increased, with the performance of angular contact ball bearings, can withstand higher axial loads. The bearing friction coefficient is small, high limit speed, different size and forms. Solid and durable, strong versatility and low noise operation, easy to install and can be run at a high speed. The design of deep groove ball bearing and sealing, without lubrication and no maintenance. Separate with ball gap and double ball bearings, suitable for heavy load. Condition.Thrust ball bearings: rolling bodies are thrust ball bearingsRoller bearings: rolling bodies are roller bearingsCylindrical roller bearings: rolling bodies are cylindrical roller radial roller bearings, is a separate type bearings, installation and disassembly is very convenient. Cylindrical roller bearings are divided into single, double and four column
- 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?
- It is estimated that the bearing clearance is too large to cause vibration. If the original pump work environment temperature of 20 degrees, now 5 degrees. When the thermal expansion of the bearing decreases and the clearance becomes larger, the vibration of the motor will be too large. It is suggested that the clearance bearings be selected according to the running temperature and speed of the motor.
- Q:Bearing, in addition to interference, excessive, gap three kinds of co-ordination, there are no other coordination?
- These three types of coordination, and other coordination is only a different individual name, but the actual situation is the same
