Hi,guys
I'm looking for good power grease gun(electric powered) fore greasing yp 100-600HP/2P motor bearings,normally 6313/6316 bearings.
There are so many choise. I concern that high volume grease gun(like 10oz/min) might blow seal.
I wonder what kind of power grease guns members in this board are using?

Why do you need a power grease gun? Why not use the old fashioned hand-operated kind.

By the way, in case you haven't heard my soapbox speach... 6316 bearing at 3600 rpm is operating at or beyond the reasonable boundaries where grease lubrication will operate reliably imo (and according to many handbooks). If our experience is any guide (we have a few of these), you can expect fairly short bearing lives.

Hi
I agree. 6316 may be undersized for 600HP Toshiba motor. I saw Baldor 700hp/2p motor used 6217 bearings that was short lived.
I have to grease up 10-15 motors and low pressure hand grease gun needs 33 pumping for 1oz of grease.Do the math

There are some autolubers that operate on low pressure that might work. If you're interested, reply as such, and I'll post the website of the one's I'm talking about. I'm a big fan of autolubers because they lubricate equipment with small amounts of lube continously instead of large amounts periodically. They also lubricate while the machine is operating, which is better then lubricating while its not.

I visit two facilities where they use the 18V (i believe) Lincoln guns. Both facilities have managers that would throw them in the river if they could get them away from the oilers. The oilers like them because they don't have to do any work, just pull the trigger.
The managers hate them because they have grease everywhere now, and yes, the seals are being blown (MANAGER: Why did you run grease in that bearing until it came out from under the guard OILER:It wasn't me, I only let it go pchu, pchu, and quit. )

We all (Me and the two reliability managers) believe the old fashion way (as EPETE mentioned)is still the best. If it takes you that many pumps to get an ounce of grease, I suggest you get a better gun

The lincoln gun gives an exact quantity per stroke which can be felt if the operator pays attention. The remote air type in a noise area may not be heard. I would think if the lubricators are over greasing, they either don't have an exact frequency/qunatity chart or they don't care. Give them the chart and directive or a gate pass.

Management should give direction! Have vented plugs, follow procedures, etc... If they don't have procedures nor have been trained, then management is at fault. The PM should say; equip ID, brg ID, frequency, quantity and include cautions. If then you have problems, it lies squarely on the tech's shoulder.

Because I am in a food plant and started on the floor in maintenance, when an OEM spec calls for two hundred shots of lube to purge CIP chemicals, I definitely see the value of a self operating grease gun!

I agree with both the end and the means of Sam's statement. I see an awful lot of over greasing in general, with or without a powered grease gun. We have begun adding detailed instructions that cover re-lubricating motors specifically. Nearly every motor manufacturer publishes a load and speed to hours run chart that includes quantity of lube to be used per motor frame size. Mandating (for lack of a better word) how much lube to use has actually eliminated some of the monthly re-lube PMs.

As a test of the newly written lubrication work order we started with one machine as a pilot project for 1 year, a 40 HP Baldor in-line coupled to a Hoffman three stage blower at 3600 rpm. Now PdM is the only information used to determine bearing health and re-lubrication requirements. The machine is now in it’s third year and running as good as it should. The techs use the 18v Lincoln Auto-lube. More machines have been added with the same success. We are now calculating the reduction of time based PM activities as a cost savings and progress monitor of the PdM program.

Perhaps an electronic grease meter would help:

Typically I take an electronic scale and weigh the shot of grease and label the grease gun. As Dave mentions; a meter eliminates the need to calibrate and/or count pumps.

Hi,Guy Thanks for info.Here my selection for now. Alemite hand grease gun with grease flow meter. I just wonder that grease up motor bearings is very critical maintenance practice;however, there is not enough tech assist such as controled grease flow meter. Here is my thought.
"Grease amount control meter"(whatever...)
1.Operating mode selection.
1-1.Flow meter mode....meter grease flow.
1-2.Control flow mode...go to next selection
2.Control flow mode selection
2-1.Total flow control mode... flow exact amount specified.
2-2. Bearing type mode...entering bearing model(6313,6211,nu2315....) will automatically determine amount of grease to fill.
3.Controlled flow mode
"Enter amount of grease" then eneter whatever amount...then go to final question.
4.Bearing type mode
"Enter bearing #", this will determatically determine amount of grease by looking up data base....then go to final questions.
5.Final questions
"Did you open the grease drain plug, y/n"
Entering "Y" will start greasing. Final question can be modified and add questions such as "Check type of grease y/n"....etc
There should be low/high volume selection switch somewhere on the powered gun. Then pull the trigger or hand pumping will start measuring total grease amount. It will shut off when it reaches to predetermined amount. No more over greasing. Alemite grease flow meter cost $180-$200. This inovative grease meter should cost $300-500.

Trico has the same meter for 417.00 USD
Great tool. |

A 'better' gun? I believe that 33 pumps per oz is pretty much industry standard. That's what my Lincoln guns put out (I know it because I've engraved it on the guns), and they're pretty high-end units. It doesn't matter whether it's a lever style or pistol style, 33 pumps per oz is what I get from a good gun.
That having been said, I have a power greaser (the type that sits on a 5 gallon bucket of grease) in my shop, but it's only used by the forklift maintenance guy for greasing the outdoor forklifts. There's a Lincoln portable power greaser in the crib, too, but I've never tried it out. I'm just old school, I guess, and my needs aren't as great as those of some others. I probably only pump 4oz of grease into the machines per week on average.
