- 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:Compared with other bearings, what is the application performance of NSK Bearings?
- The quality of NSK bearings and all aspects are good, after all, is a big brand!
- Q:I want to use laser displacement sensor to measure the displacement of the slider. I hope the master will recommend a sensor.
- A ZLDS100 laser displacement sensor is a digital integrated structure with no controller and direct digital output.
- 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
- What is your department, I also do bearings, practitioners have been 20 years, I hope to exchange. Please leave a contact information.
- Q:What's the bearing fillet of the 7003C? Do other bearings have the same fillet?
- The other bearings don't have the same fillet, and the bigger the bearing, the bigger the fillet.
- 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: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: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?
- 1, first of all, do not know what you are using bearings, I do not know if you choose the bearings there is no problem.2, secondly, if you choose the correct bearings, shaft and bearing installation is not a problem? Preload is not enough? Loosely matched?3, it is best to know the motor power, you choose the type of bearing. In this way, we will give you the correct answer to the question ah.
- 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:Are there any differences between bearings used on fans and other ordinary bearings?
- the fan usually has two ends adjustable heart or one end of the cylinder with diagonal contact at one end.
