Question:

The correct detection of bearing oil?

How can we know the spherical bearings inside there is no oil or have what instruments?For example, UCP212 bearings, how to know that there is oil in bearings, without bearing the premise of the pry?

Answer:

Detection of spherical bearings have no oil inside the instrument? This, as far as I know, spherical bearings in general, in addition to the gap to fill up between the bearing seat and the bearing outer ring, bearing itself is like ordinary with iron cover or cover of deep groove ball bearings, it is testing is not oil, grease is adding a maintenance free but, if that is because of environmental conditions and other causes of oil deterioration failure, this set of bearings also need to be replaced, so the best detection instrument is, if there is noise, Wen Sheng, vibration or friction increase when the bearing life is up, need to be replaced. If it is a short time, or the quality of the bearing itself is a problem, or design selection, the above problems
UCP bearings are spherical surface ball bearings, both sides have dust cover, the grease inside must be some. Dust cover can be removed
This method is relatively simple, if you are a manufacturer, you put a no weight bearing oil first, and then take an uncertain bearing compared weight, can be seen in the end with a little oil, because the bearings are of high precision products, usually each important does not differ too much. This method is enough. If you are using, you can go from the oil hole of the gas, until the sealing ring out of oil, because usually spherical is low bearing, not because of excessive oil and lead to overheat and burn bearing operation. Thank you
Bearing with dustproof cover, no matter what kind of material, what form of contact, with sealed cover bearing, no matter which brand, the factory has been filled with the right amount of grease, enough to use the end of bearing life.The spherical bearings are designed with most of the oil hole, directly connected to the bearing seat, oil injection nozzle. With this design, the life of the bearing can be extended to the maximum extent.
