- 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:sometimes to the other bearing sliding bearing number, sometimes to the sliding bearing parts inside, why?
- Sliding bearing partsThe bearing is sliding bearing and shaft parts, very smooth, generally made of bronze, anti friction alloy wear-resistant material, in particular, can be made of wood, plastic or rubber.
- Q:Feroform what bearing material, metal or nylon, or anything else?
- Stand erect, stand firm, stand erect, erect, written, erect, erect
- Q:I need regular manufacturers' agents (with authorized certificates and large scale agents)

- 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.
