I would like to ask practitioners how, and specifically what to remove the bearing in the situation shown in the picture. There will be no puller tabs between the bearing and the ring next to it. What do you use in this situation? This is an old ZELMER vacuum cleaner, but the problem is universal .

I will answer stupidly - puller. A smarter version of this statement is the slogan bearing peeler. And the blacksmith, it is crushing the outer race in a vice and grinding what remains - so as to cut it, then it will come off without a problem. Look.

Secure the commutator and the winding and do as your colleague wrote robocop with the puller method, there is a possibility of damage to the impeller

The method described by the Robocop col. Is practiced even in authorized power tool services. That is 100% efficiency!

There are professional presses for such cases, which have two jaws ground at an acute angle going under the bearing. It is enough for them to slide in to a depth of 0.5-1 mm. Something similar to the item in this set, bottom right.

If you have an angle grinder, put a small disc on it and get to work. First, cut the outer flange of the bearing in two opposite places and remove it, then cut the ball basket and you will see the inner flange. Cut it carefully, being careful not to cut the rotor axis. You can cut it in two places. Then you take the hammer and, resting on the rotor's anvil on the notched flange, strike it vigorously. It should break at the incision and after the competition.

Once, I quickly made such a device out of two flat bars and a vice.

And protect yourself from spatter. A cracking bearing ring can emit fragments in undefined directions.

There are small pullers for small bearings.

The topic is exhausted, I close. God forbid, if somebody slips over the advice of hammering on the head with a hammer ...

Topic summary

In situations where there is insufficient space for a puller to remove a bearing, several methods can be employed. One approach involves using a vice to crush the outer race of the bearing, allowing for easier removal. Alternatively, a custom device made from flat bars and a vice can be quickly fabricated. Professional presses with angled jaws designed for bearing removal are also available. For those with an angle grinder, cutting the outer flange of the bearing and then the ball basket can facilitate removal, followed by careful hammering to break the inner flange. Safety precautions, such as protecting against flying fragments, are advised during the process.
