- Q:A winter hand is out of the question, always pull the beginning of a circle when no problem, after feeling a little strength are not, pay attention to the following 2: 1, the legend of the hand is slipping should take a one-way bearing cleaning, I remove the bubble in alcohol and with ultrasonic cleaner washing, the result is really good for a moment, the next is not good; also for the one-way bearing, when the hammer is likely to change in the same phenomenon. 2, this is a method I find, is the first at home to the engine oil pump, the pump to the obvious rich and even a little bit when misfire, hand is good, get out after the fire down soon start pouring fuel, normally is not a one-way bearing can not enter fuel? Late into the fuel hand puller is obviously not slip like a long time don't see is what reason, solution!
- Is the quality of bearings, the size is not standard, because the axis tolerances are limited, resulting in a loose tight. Replace the bearings of better quality.In principle, the general transition fit, one-way needle, this structure is too simple, and the accuracy is not high, the domestic small factory product quality is not stable.A one-way bearing is a type of bearing that can be turned freely in one direction and locked in another direction. One-way bearings, also known as overrunning clutch, but according to different industries, the role of different naming.
- Q:Since what year did NSK begin to provide bearings and other related components for the aircraft industry?
- Look! How strong is our motherland! But we can't be content with that.
- Q:FAG bidirectional thrust angular contact bearing 234416M.SP can be replaced by other manufacturers?
- Japan NSK Code: 80TAC20XLJapan NTN code name: 562016SKF code name: 234416TN9/SPDomestic HRB Code: new code name: 234416. Old code name: 2268116
- 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:I feel different from other factories, ah, there is no pungent smell!
- You go to Harbin axis Ji'nan company to ask, they are the factory's direct center, can solve your problem
- 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: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: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:What does 7 represent? What does the rest represent? If 7 is changed into other numbers, what does it represent?
- This is a model of SKF bearings7 represents the bearing type as angular contact bearing3 represents the width class0 stands for size class8 represents the bearing inner diameter of 40, after the general bearing two digit multiplied by 5, is the bearing bore diameter
