using pre-lubricated bearings in gearboxes/speed reducers
Registered Member The RCFA has officially come to a conclusion. In a convoluted way, as suspected, fitment interference and lubricant incompatibility may or may not have contributed to the recent failure(s). The admission, perhaps driven by “goodwill” comes in the form of total replacement of 8 reducers at a significant cost to SEW Europe. Considering mounting position, aluminum complex grease will not be included during the assembly of the new reducers. In this case we used 4 PdM tools and our “human senses”... [ more ]
Registered Member Good to hear - I took "prelubricated" to mean a sealed-for-life bearing, of which SEW uses many deep groove type. It's that type of bearing that is not regreasable and therefore the manuals require annual rebuilds. Sounds like a pretty clear picture at this point. Good luck with the units. [ more ]
Registered Member Yes this is a food grade application and these boxes are less than 6 months old. These boxes are the K series. They are multi-positional and consist primarily of cup and cone bearings which are not sealed for life (in most cases). The bearings are packed with the AL complex grease to ensure the bearings not in the oil bath receive some lubrication. I would prefer to see some sort of slinger to achieve lubrication as opposed to adding an additional piece acting as a seal between the bearing... [ more ]

"purging" incompatible grease
Registered Member Ok, but who is it that you are disagreeing with. On the surface it sounds like you are saying that my recommendation was that “ignorance of grease types is a safe place to operate”. I doubt that's what you meant, but if it was then I will respectfully disagree with your characterization. I have suggested the only 100% technically correct answer is to change out the bearings/grease, but from practical standpoint there may be room for engineering judgement in the selected approach ....and I... [ more ]
Registered Member Have you mixed these greases in a test sample to see what happens? Mobilgrease 28, being a clay thickened grease, may in fact work well enough in mixture to use a series of regreasings to reduce the amount of 28 to an insignificant amount. The only way to know is to try it. Obviously, high speed / diameter bearings will need to be handled carefully to avoid overgreasing. Of course the other option is to take precautions to ensure the correct grease is always used, whether it's Mobilgrease 28... [ more ]
Registered Member Seems to raise some problems: 1 - If purging means the new displaces the old... how can it happen without mixing? It can't. 2 - Some people are inclined to add large quantities of new grease in attempt to force the old grease out. Creates a whole new problem - overfilled bearing - particularly a problem on high D*N bearings. 3 - I heard someone recommend pressurized air once to push out the old grease. What are the odds it would really work completely and how complete and what other problems... [ more ]

a "field test" trick
Registered Member Wow! I can apply that to an application right now! I have a couple of air mist oiled 10,000 RPM spindles driven by 150 HP motors that fit your description perfect. We collect PdM data on the machines monthly but because of the speed involved PdM does not always catch a failure. To catch every failure, alarm triggers would have to be set too close to actual running conditions which causes a lot of false positives. The mixed load of steady and shock make it even more complicated to alarm using... [ more ]

Maybe I'm missing something (water in oil)
Registered Member Don, sorry I didn't see your answer from before: At this point we are recommending that the customer install a system that allows the observation of free water as well as desiccant in the headspace to reduce water formation. We don't think further analysis and thought is required until they can show the free water is stopped, since in general with these gearboxes water should not be getting in. At the very least we now have some knowledge that lets us think deeper about trusting simple water... [ more ]
Registered Member DAvid, I'm with you about if 250ppm is something to be concerned with when the oil naturally holds at 250ppm. I think it would depend on the customers system and the effect they may know it has with reliability. I work more with turbine oils and below 200ppm is acceptable. What temperature does the free water collect? What temperature does the oil operate and what are is hours of service per day? When does water become free. Coalesce filters are great for removing free water. Filtering the... [ more ]
Registered Member The viscosity is 320. I don't yet see the advantage to being below 200ppm except that maybe it makes the oil analysis more valid(?). I think we first need to solve the removal of free water, and then decide if pushing below 250ppm has a benefit. David [ more ]

Lead in T/G Oil - No Tin
Registered Member Because of environmental/safety issues I would really be surprised at a lead based bearing if this was a machine made in the USA in 2005. However, Toshiba comes from Japan so all bets are off. If you have some spare bearings you might check the appearance. Lead based bearings often present a surface that is dull and gray whereas a shiny surface indicates tin based. This isn't a perfect test however as some new bearings are shiny regardless. It is important to know because when reclaiming an... [ more ]
Registered Member Thanks for all of the excellent comments. Some more information- This machine is a 2005 Toshiba T/G. I am in contact with Toshiba to determine the babbitt composition. Oddly enough- there is a section in the Maintenance Manual titled "Bearing Metal" but makes no reference to the "bearing metal". I also discovered that Insight and Signum do not test for antimony, although Insight may have a test available. I am pursuing this also. We have considered lead as a contaminant due to the lack of... [ more ]
Registered Member Lead can be a contaminant also. This came accross my desk this morning. In this case the lead is obviously not babbit because machine is rolling bearing. Pretty clear there is contamination problem of some kind due to presence of silicon. I'm not sure what type of contaminants typically contain lead. [ more ]

Registered Member Hi Wendy You may need to talk to the Company that you send your samples out to about the alarm sets used on all your Gearbox's, they can be taylored to your needs.

Registered Member Hi Wendy, from the viscosity results the conditions in the gear boxes are not all the same, conditions that could reduce the viscosity would be fine dirt entry damaging the lubricant, oil age very old in some drives, some type of liquid contaminate gaining entry diluting the lubricant, if the original lubricant was an ISO 220 then the reason for the viscosity reduction will need to be root caused and prevented, Regards Rob S [ more ]

Registered Member Thanks Richard. I've got another round of samples in transit for further analysis. I just inherited this PdM program and the lubrication program is rather chaotic to put it politely. One plant has 16 turbines with half using one vendors oil and the other half a different supplier with plans to introduce a third type of oil on one unit. They have been taking samples (unknown quality control) and sending them to various labs over the years so putting together the history of the LOA is a real... [ more ]
Registered Member I would not recommend action on one test alone. It is not clear from your post if you have a trend of data for each unit or if the bunch of reports are from one set of samples for each unit, but one data point certainly is not enough information for a recommendation to change tens of thousands of dollars worth of oil, and re-additization is usually not recommnded by the OEM's. Having said that there may be a host of things you should recommend, depending upon the oil condition in the units. [ more ]

Registered Member Ok, you want to control the amount of grease being injected by their respective weight by cm3. It's called precision greasing, isn't it? I thought your vendor would have that database ready for you, won't he? [ more ]
Registered Member The amount of grease dispensed per pump can vary from one grease gun manufacturer to another. To better control the amount of grease during re-lubrication it is advantageous to know the quantity being delivered. Most of us have seen crafts people shooting grease until there is a “sign” and that sign is usually grease escaping from the seals. At that point the bearing life has already been shortened.

Registered Member That appears to be a typical defect in the ball. From what I see in the picture there was an air pocket in the ball bearing material and it was ground to size and placed into the bearing.

Suction line insertion point in the kidney loop system

Registered Member The only official reference I have on hand is ASTM 4378-97 that shows a warning limit of 0.1% or 1000PPM. Way too high IMHO. That standard has been replaced by ASTM 4378-08 which might have some updated info but I don't have a copy so I'm not sure. Personally I wouldn't run at 1000PPM without taking some immediate action to knock that down. I like 200PPM as a target. Is there an ISO code out there somewhere? [ more ]
Registered Member Oil Labs have limits for water in turbine oil. They will alarm given water ppm meets that level. Typically we want to keep the water ppm below 200 in our turbine generators. This is an ISO 32 oil. It has been significantly higher than 200 ppm without wiping bearings but it will cause reduced life of the oil and can create rust of internal components. Of course, the lower ppm the better. Recommend checking with the oil and machine manufacturer and the labs you do business with for details. [ more ]
