Simple screw bearing puller made of stud and bolt

Simple screw bearing puller made of a stud and bolt Hello to all homemade products! In this article, we will consider in detail the assembly that is quite useful in the household, and not only homemade products, which, in turn, as expected, will be assembled from the most available materials. The design of the homemade product is quite simple, so no one should have any difficulties in assembling, and from the skills it will be enough to have at least, simply, “straight arms”. So we will assemble a tool thanks to which you can easily remove the bearings. Often, when it is necessary to remove some bearing from somewhere, and usually these same bearings are pressed onto the shaft, and this is still half the trouble, since often the bearings “stick” and the joints corrode. In this case, in the absence of a special puller, you have to fiddle with a hammer for a long time, so this homemade product will save you from such difficulties. Well, well, I think you shouldn't delay with a long preface, let's go.
For this bearing puller we need the following, namely:
– Thick metal stud
– Thick and long bolt
– Nuts on the stud and on the bolt
– Screw
Of the tools you will also need the following:
– Drilling machine or ordinary drill
– A set of various drills for metal
– Bulgarian
– Various cutting and grinding discs for an existing grinder
– Welding machine
– All attributes necessary for working with the welding machine
– Ruler/tape measure
– Marker
– Vise
– Some kind of paint to protect the metal from corrosion (optional)
– File
– Gas burner
– Wrenches
– Thread lock (optional)
Making a compact screw bearing puller:
First, we need to get a thick and long bolt. In general, I recommend choosing some kind of bolt with a very fine thread, so that there is an increased number of turns of the nut on this bolt, thereby removing the bearings will be much easier than with a standard thread. But if you are not a turner, then it will be quite problematic to find such a bolt, so you can not bother so much and use a bolt with a standard thread.
Simple screw bearing puller made of stud and bolt After we have finally decided on the choice of a bolt, in this very bolt, we need to make a hole perpendicular to the bolt itself right at its” head “(see photo below). A screw will be inserted into this hole, which in our case will be used as a handle. With the help of it, we will rotate the bolt around its axis.

We will have this pointed part as an emphasis, which will abut against the shaft from which the bearing is being removed, we sharpen it without fanaticism, the end itself should be slightly filed. This is necessary so that the stop does not slide off the shaft. We will grind with the help of a grinder and a grinding wheel worn on it.

He hardened it using a high-temperature gas burner, simply by heating the tip of the bolt itself, but you can harden it using some of your own technology, because I know that craftsmen on the Internet have come up with a large number of methods and methods for hardening different metals. Also, after the procedure, the author decided to grind the tip of the bolt to a shine.

In this very nut, it is necessary to make a through hole, the hole should be the same diameter as the same hole drilled in the bolt at its head. After drilling the hole, screw the nut onto the bolt so that the holes on the bolt and nut coincide. In this design, you can do without this nut, here the nut plays the role of thickening, it seems to reinforce the bolt. Without this nut, the handle rotating the bolt can expand the bore and bend itself, with the nut it is possible the same thing, but only with the nut it will be much more difficult to do it.

I recommend using the longer screw, as the longer the screw, the easier it will be to rotate the screw. To prevent the inserted screw from falling out at its end, tighten the nut, but this nut should not be tightened to the end, since during operation it will be quite convenient to have a screw moving from one edge to the other. But so that the nut screwed onto the end of the screw does not unscrew, it is necessary to tighten the second nut and pull them together using two wrenches. It is advisable to use a thread lock in this connection.

As it was not difficult to guess, the basis of this moving part will be a nut with the same thread as the main bolt. A couple of smaller bolts must be welded to this nut. They should be welded on opposite sides from each other. Having welded the bolts to the nut, we cut off their caps with a grinder.

We will make them from a relatively thick stud, the thicker the stud you take, the more reliable the tool will ultimately be, again without fanaticism, the thickness of the studs you choose should correspond to the size of your homemade product.

So, in order for us to ensure their free movement along these bolts, we simply take a drill of a suitable diameter and drill the thread cut inside the nut (we need this movement to grip bearings of different sizes). Be sure to check the free play of the nuts in the welded bolts, the nuts should move calmly and allow the studs to tilt at different angles.

You choose the length of the studs individually for yourself, or to be more precise, for your specific needs. Then, grooves (hooks) should be cut out at the ends of these studs from the inside, due to which the stud will cling to the bearing. That is why at the beginning I mentioned the width of the studs, since now we will narrow the studs, they can simply break in thin places. Therefore, you need to use thicker studs. The grooves themselves are first carefully cut out with a grinder, then we grind them down with a file. As a result, you should get the grooves as similar as possible to those shown below.

We tighten the nut with welded bolts onto the main bolt, then we put on the studs with nuts, and so that the studs do not fly off to the ends, we tighten one more nut each. And that's it!
