Q:I see, manual roller bearings, bearing room width is significantly greater than the width of the applicable bearings (bearing room 65, bearing thickness only 37), I would like to ask the outer ring bearings in the bearing seat in the axial direction of how to fix, plus GASKET?

This one is still fixed

Q:What brand of material is used for rolling bearings?

Sorry, I don't have much research on it

Q:Encountered a problem: how to measure the bearing seat insulation after generator operation?. It is said that the bearing seat must be insulated, and the insulation is not good. What harm does it have? Expert guidance please. Thanks very much。

The landlord does not know whether this problem is the power of professional, I have seen two, do not know is you, why should the bearing insulation, when the generator is running, because the electromagnetic induction problem, will produce axial currents in large shaft, if between shaft and bushing formed circulation, there may be ablation the tile surface (or contact thrust head and shaft surface), so it should be insulated pad between shaft and bushing cut loop, which is why the insulation should be, but I think, if not the alloy tile, but fluoroplastic itself, has not added tile insulation, insulation pad, but due to installation problems in general, the unit with insulation pad, you ask what is in operation when the pad is insulation insulation detection device, I think it is not necessary, may not, because there are water guide bearing alloy tile (if it is ), we generally think of between the guide bearing and shaft is oil film, but if the guide bearing and shaft touch, insulation pad protects you, this may be the uncertainty of it, in addition to the protection of the electrical design requirements, not forced to set up to test the insulation pad insulation measurement device, the insulation is not can the long run? And I think there is a certain value on the line, such as 100M, is not a direct short circuit on the line, how to measure 500V, shake table, shake it, the other shaft grounding is not for you to test the bearing insulation, I know from the situation, to the general rotor one point grounding quasi the preparation of the large shaft grounding can not be measured, is, on the negative resistance, I do not know the answer if you are satisfied with the

Q:For example, locomotive bearings should be pressed into the bearing seat, very tight, if will be broken with a hammer like bearing, what way.

Manual repair: can use and bearing ring diameter similar to steel cylinder pad, in the bearing, find a piece of iron pressing

Q:How can I take the bearings out of the bearing seat?

There are many kinds of bearing housings, but I don't know what they are

Q:F210 bearings with what type of bearing?

Equipped with outer spherical bearings, usually with UC210

Q:What is the distance from the outer wall to the end of the bearing housing? What is the end of the bearing seat?

The bottom surface of the bearing seat is the end face

Q:The utility model is a vertical shaft with a ladder shaft, and the upper part is a motor reducer, and the middle is a bearing seat (both ends of the bearing seat are 32218 and 32217), and the following is a chain wheel

This is rather troublesome. Are these bearings paired with each other? Or separate seat blocks? Besides, you didn't say grease lubrication or oil lubrication. No legal bearing seat type

Q:Meet an emergency！ What's the best way to remove the metal chip (because it's too thin and only a few wires thick)?

The gap between the outer circle of the motor bearing and the end cover and the bearing seat hole shall be treated by metal electric spraying.The end of the motor, bearing position, due to poor coordination of the manufacturing or bearing oil shortage, ball bearings, such as damage caused by the rotation of the outer ring bearings, long time, there will be motor rotor, drag shell, and moving, and so on. The following ways can be solved.1, the end cover for cast steel or cast aluminum, bearing should be carried out outside the ring metal spraying, so that the outer ring and the end of the cover close cooperation.2, for emergency use, according to the size of the gap between the choice of copper foil, with epoxy resin fixed on the outer ring of bearings, and then into the bearing. After drying, it can be used.

Q:What is the difference between UCFC bearing seat and UCF bearing seat?

You can see the two bearings together.
