TIMKEN bearings, lubrication method, divided into the grease and oil lubrication. To make miniature bearings play function, first select the appropriate conditions of use, the purpose of lubrication method. If there is only a lubrication, oil lubrication lubrication dominant.
However, the grease lubrication expertise can simplify the bearing of surrounding structures, the pros and cons of grease and oil lubrication.
The most commonly used in miniature bearings, stainless steel 440, it is sufficiently hard and solid to load (20%) less than the brass, steel, but it can rust, you can put up with the instant high temperature 250C and 300C of the sustained high temperatures. We often mistakenly thought that all of the stainless steel is not magnetic, 440 stainless steel is magnetic, it is not completely rust-proof, but by salt, acid and alkali. Antirust 316 level of performance is very good, is not magnetic, but relatively soft so the load, it is not solid, bearing 316 precise degree is not high, rough feel.
When the advantages in the detection of chrome steel and stainless steel as TIMKEN bearing materials, they are not only with rust. Chromium steel is the most common micro-bearing materials. It is harder than stainless steel, so a longer service life. However, at higher temperatures, its performance is not how.
120C high temperature, it occurs to a great deformation of the load decreases. 150C of the high temperature it can tolerate it, but the instant 150C or higher temperatures will reduce imports of bearing life. The heat treatment allows the bearing to withstand a moment of high temperature 170C.
