Lubrication for BOSCH Grinders: Gear Grease Recommendations, Viscosity, and Quantity Considerations

I can't find specific information on gear lubrication in grinders. Different lubricants are given, but I checked two Łk-43 and another one recommended on the forum, the name of which I can't remember, and it applies to heavily loaded bearings and gears.

The conclusion is that none of these lubricants do their job to the end. The latter is quite rare and when it smears the wheel it works fine, but it is soon thrown out by centrifugal force and the teeth go by ear. The grease is everywhere except on the teeth. I mixed two grade 00 and 2 greases to thicken. The effect is that after folding it works fine and is not thrown away right away, but when I left it with the axle up for the night - the grease flowed from the teeth and the grinder ran dry again. I'm already confused on this topic. Why does the grease not accumulate on the teeth, as in drills, where the grease is thick? How to improve the viscosity?

And what about quantity? If there is a lot of thin grease in a very large amount, so that it has to be lubricated somehow, will it heat up faster, burn out?

I did not check the lubricants recommended by the manufacturer, because they are a bit too expensive, and I am interested in a fairly universal solution. Although with the current problems, I have to try.

But he's holding his teeth.
I used a high-class grease - blue, ductile - it is used for hubs in truck tractors.
None LT 4x.

PHASE EPS-1

Proven for years and costs pennies.

@ jannaszek: I am looking for a lubricant for the service, not for one lubrication. The ones recommended by Bosch cost about PLN 150 for 250ml. So it comes out to PLN 7-8 for lubrication and no one will pay me for it, because the customer is of the opinion, why lubricate when the lubricant is still there, or put Pan towot like waceko12. And then, because my teeth are chattering, and the Lord was fixing it.

@PtasiorWro: colleague as always specific.

I did some reading in the meantime.

Some recommend 00 or 0 grade lubricants.

Lubricant classification:
Consistency class
000 very fluid
00 liquid
0 semi-fluid
1 very soft
2 soft

Lubriten EPX-000, EPX-00, EPX-0, EPX-1 greases are used depending on the gear structure, degree of sealing and temperature:

Lubriten EPX - 000 - for lubricating the gears of rotary mower mechanisms.
Lubriten EPX - 00 - at lower temperatures of the given range and with good sealing of the gearbox.
Lubriten EPX - 0 - in intermediate conditions.
Lubriten EPX - 1 - at higher temperatures of the given range and with poor sealing of the gearbox.

Mixing incompatible lubricants can lead to damage
mechanism. Especially bentonite and polyurethane lubricants
and perfluorine are not miscible with the others.

I will add that the zero class is too fluid for grinders and hammers.
The original Bosch grease is class zero, but it works only with new tools, as there are new oil seals and o-rings because after some time, especially at high temperatures, it starts to leak from every hole.
In our company, we use EPS1 for gears (grinders, wall chasers, impact drivers, etc.), 2-pound hammers (GBH2-26, PPH30, DH24, HR2450) to demolition hammers (USH27, Milwakee 2500, 900K) and other tools where it is required lubrication.
We only pour oil into new Hilti hammers and diamond drills (CARDI, REMS, etc.)

For the Bosch GWS 14-125 angle grinder, I used Husqwarny grease for the angle gears of brushcutters (225 ml tube for PLN 23). The angle grinder has quieted down and the gears do not run dry. Kątówka has a lot of hours worked.

Will this EPS-1 grease also be suitable for lubricating SDS terminals?

It seems to me that this grease will be too soft and too thin for SDS tips, but it's better to put something on it than nothing. I personally lubricate EP-2

Returning after some time to the topic of lubricants. I wonder if thick casein oil is suitable for gear lubrication? I have a lot of it.

The lubricant recommended by PtasiorWro is elegant, I use it every day now.

However, sometimes when I open grinders from customers there is this very sticky grease, very sticky. It was also similar in the transmission of a self-propelled wheelchair, where there may not be high revolutions, but a large load. I would like to know what specific it is.

I will answer my own question about sticky lubricants. They are used primarily at low speeds and high loads. In the event of high revolutions, the grease as well as the oil should not be viscous. It acquires proper lubricating properties only during operation.

I am currently interested in Makita P-08361 semi-fluid graphite grease - do you know the equivalent?

What lubricant do you use in drills, mixers (approx. 2000W)? The grease used so far burns out, and I used EP2 from a good company. what do you use?

I use FAZI EPS 1 from Czechowice Dziedzice.
It works well with hammers as well as with slower machines such as stirrers and magnetic drills.

Is this FAZI EPS 1 also suitable for stirrers? When I open the machine, there is quite a thick grease there and I tried to apply it, sometimes I put phases, but without conviction. So, in general, this samarium can be applied to young, slow machines with a greater load, but also to high-speed grinders or polishers, right?

I'm digging this topic, because not which companies I repair tools get equipment and wrongly selected lubricant or amount takes revenge. I haven't had a problem with this grease yet, but with others I've had. A grinder that runs for a few hours without major breaks quickly returns, but hopefully not with the same fault. I often waste time wondering if this grease will be suitable.

I used to work in a power tool shop. Lubriten EPS-0 for grinders, Lubriten EPS-1 for hammers - such lubricants are also recommended by Celma, the manufacturer of power tools. More expensive professional GBH hammers and other tyranny by companies were lubricated with Bosch's dedicated grease (thick, sticky), or after agreement with the client (if he wanted cheaper) also EPS-1.

For the bevel gear in the AEG WS2200-230 grinder, I used brushcutter gear grease. It works quietly and has not spilled grease from the gear onto the cover. It seems to work well for this purpose.

I just see that colleagues use the same grease that I bought FAZI May EPS-0 EPS-1 and EP-2

Hello everyone,

I bought a used Milwaukee CAG125 grinder. After I bought it, I opened it to refresh it. I also opened the gearbox. The grinder was rather little used and the amount of grease placed there and its density because it is quite thick - thick enough that it does not participate in the lubrication of the gear.

I assume the grease is original. I assume that I will not get a better one anywhere except the manufacturer.

Now the question is what to do with it? I'm currently lubricating the gears and closing the case, but I think it's a temporary solution. Isn't it better to clean the gears and give something new and in what quantity?

Hello - I used EPS0 for the gear and the gears are now not dry, and they were dry, but I heard from one of the experts that the gears are dry when cold, nothing bothers me because when the head warms up, the grease splashes - this kind of thick and it also makes sense because the head actually heats up, don't throw away the grease, possibly add Fazi EPS 0, it should be ok, after some time you can open it and check if it has weighed or if there are no lumps, EPS 0 is probably the rarest grease from Fazi , thinner probably would not make sense because it would be approaching the consistency of oil and could leak outside the housing - best regards

I'll check it. I'll run it for a few minutes and let it warm up. We'll see what's inside. I'll put it down to cool so that it flows by gravity onto the gear.

When it comes to adding to the existing one, the idea is rather out of the question because if I mix two with different parameters, it is not known what I will get and whether it will stick to my teeth at all..
