Specification ofElectric Motors and Electric Power bearings:
Through unremitting efforts and experimentation all these years, CNBM has successfully developed bearings that can meet the requirements and work properly under severe working conditions. As a result, our bearings are popular among motor manufactures and manufactures of electric power tools.
Meanwhile, due to the improvement of bearing materials and manufacturing technology, bearings practical reliability is effectively guaranteed. The quality of electric motor bearings has reached the international advanced level in the high-reliability requirements of the occasion can be used to achieve reliable import substitution, the new "TD" (Technology and Development) series of products that meet the market demand for these high-end purposes.
- Q:How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.
- Q:Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
- I don't know what you mean. The size of NUP2311E is: inside diameter, 55mm, outside diameter, 120mm height: 43
- Q:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?Semi convex, convex roller is in plane roller axis, the outer surface of a continuous or discontinuous convex curved basic cylindrical or conical roller, to prevent the end of the roller and raceway contact stress concentration. The roller is generally defined as a convex roller and a modified roller.
- Q:In the car there is a cylindrical roller, the size of the diameter of 25mm, the outer diameter of 32mm, width of 9.5mm, who knows what the standard size, have direct purchase Mody, thank you!
- There is some doubt about your description. According to your internal diameter and external diameter, if the cylindrical roller bearings, the scroll is quite small. I don't see much of this kind of cylindrical roller bearing. Do you mean needle roller bearings? If needle roller bearings can be found, and HK2514/18 RS similar models.
- Q:How are the twin row cylindrical roller bearings classified?
- The NN0000K type conical bore double row cylindrical roller bearingThis kind of bearing is compact in structure and bears little deformation under load, so it is suitable for the support of spindle of machine tool. The inner bore of the bearing is taper, and the radial clearance of the bearing can be adjusted slightly.This kind of bearing with no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or shell, cylindrical roller bearing with the same radial size is compared, can bear larger radial load.
- Q:What's the difference between imported bearings and imported bearings?
- Domestic bearings used in the cage and rivet and washer, spacer ring, sealing ring, pillar, pin etc. the material is divided into black metal materials (such as low carbon steel, stainless steel etc.), non-ferrous metal materials (such as brass, bronze and Aluminum Alloy etc.) and non metal materials (such as plastics, phenolic textolite three) etc..
- Q:How to check the thrust cylindrical roller bearings?
- Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
- Q:what does that mean? Please enlighten master, thank you.
- You should say that the Japanese NSK bearings? NSK, N216, E stands for high load cylindrical roller bearings, N216 EM, which represents high load cylindrical roller bearings, copper alloy solid cage. E, which means strengthening the design, so the load capacity of bearings is better than without E.
- Q:Why are there no double row cylindrical roller bearings in the mechanical design manual?
- So under normal circumstances, the bearing bore and the shaft is no gap.But do you mean that the inner ring and the shaft of the bearing are fixed,
- Q:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings
- 3, the bearing clearance in different conditions: the bearing clearance can be changed under different conditions, in particular, can be divided into: 1) the original clearance: the original bearing clearance refers to the complete installation in front of the machine after the bearings, the clearance in a free state of the. In fact, the original clearance is not to be measured by measurement, so the original clearance is often replaced by a test clearance. The inspection is in clearance inspection status, applied in measuring load conditions, clearance data instruments detection and, strictly speaking with the original bearing clearance is not the same, but little difference in the readings on the two in general, so it can replace each other without causing much error. 2) effective clearance: effective clearance, or work clearance, refers to the bearing in the installation of the host, in a certain load, to a certain temperature rise in a stable state of operation, bearings exist in the actual clearance. Obviously, the effective clearance is smaller than the original clearance.And 4, bearing clearance: clearance of bearing is to ensure that the bearings are to operate flexibly without blocking, but also requires that can ensure the bearing running smoothly, the bearing axis has no significant settlement, and the number of rolling elements bear the load as much as possible. Therefore, the clearance of the bearing has a great influence on the dynamic performance of the bearing (noise, vibration and friction) and the rotation accuracy, and the carrying capacity (wear and fatigue) of the bearing.
