Let's talk about the shape and position tolerances applied to the surfaces on which you plan to install the bearing. It is not so easy to obtain such surfaces in terms of accuracy and cleanliness, but it is quite realistic.
00:00 ➤ Introduction.
00:25 ➤ What are bearing reference surfaces.
01:20 ➤ Surface finish or roughness for bearing.
02:21 ➤ Surface shape and position tolerances.
03:13 ➤ Where can I get tolerance values?
And again, the tolerances and landings are on my channel. But this time we will not consider tolerances and fits on the drawings, but rather what are applied to surfaces. After all, if you need to install a bearing, then everything will depend on how the tolerances and fit of the shafts and holes will be for the mating parts. It can be said that tolerances and landings for dummies, because in my videos I explain everything very intelligibly. And after watching this video carefully, you will understand how important it is to select the tolerances for the bearing correctly. It is not for nothing that a system of tolerances and landings was invented many years ago. In educational institutions, you can hear a unified system of tolerances and landings, or, more simply, by which I choose tolerances when developing drawings. After all, any size tolerance is present on the drawings for a reason. As in principle, and landing. It is important to remember that there are still tolerances for the position of surfaces, which are also regulated by GOST. Therefore, you don’t have to ask me how to replace bearings, because these are the basics of mechanical engineering technology.
