Single Row Cylindrical Roller Bearing (NUP244) Cylindrical roller bearing NUP244 Description: *Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.
Roller bearing in the operation of the process will inevitably damage occurred, if abnormal heat, vibration and noise increase of the phenomenon of sudden, that Roller bearing may have been damaged should be checked in time and analyze causes. Common failure modes are: A, indentation When the outside world durum substances into the bearing, and pressure in between the rolling element and raceway, make rolling surface indentation. In addition,
Bearing installation, to consider the extent of other parts of the match, which required not only for the bearing itself, and it wants to meet for the parts also have requirements. As the precision bearings within its accuracy 1μm, so ask its match components (shaft, bearing, end caps, ring, etc.) have very high dimensional accuracy and shape accuracy, especially with the precision to control surface and bearing the same levels, and this point is crucial, but also the most easily overlooked.
Bearing rust process commonly used method among the following: 1. Dipping concentrated solution of sodium nitriteThe product after washing, immersed with 15% -20%, 0.6% sodium nitrite and sodium carbonate solution, then it stacked up. In this way the rust of a short, generally only 7-14 days to maintain, but also in the rainy season, wet weather, keeping only 2-3 days to be reprocessed, it takes labor and money.
One of imports properly installed precision bearings Installation of bearing products for imports for one-off installation up and pay attention to something, and if not installed, then the import will not long bearing life. So, we need the import the import bearings installed, you should know to install their own methods of imported bearings, so as to ensure that imported bearing damage during installation. Following me to introduce comprehensive check the accuracy of imports bearing installation method:
