  • SKF Bearing Knowledge: Heat bearing mounting

    Therefore the bearing, or the housing, is heated before mounting. The temperature difference between the bearing and seating depends on the magnitude of the interference fit and the bearing size. Normally a bearing temperature of 80 to 90 °C (144 to 162 °F) above that of the shaft is sufficient for mounting.

  • What's the normal operating temperature of bearings

    Sep 15, 2004 · For ball bearings used in electric motors for Aerospace and Military use the temperatures of the motor can go as high as 180 C (336 F). The lubriion should be suitable for such temperatures, the metal parts of the bearing are not affected by such temperatures.

    Normal is tough to answer. You haven't defined the type of bearing or the appliion. For sleeve bearings, often alarm is set at 180190F and shutdown is set at 200210F metal temperature. For antifriction bearings, the following requirements are given in IEEE841 (severe duty electric motors): "When direct coupled, the stabilized bearing temperature rise at rated load shall not exceed 45 °C (50 °C on twopole motors) as measured by a thermometer or thermocouple on the surface of the bearing housing as close to the outer race as possible." ===================================== Engtips forums: The best place on the web for engineering discussions.electricpete: This is not quite accurate. For ball bearings used in electric motors for Aerospace and Military use the temperatures of the motor can go as high as 180 C (336 F). The lubriion should be suitable for such temperatures, the metal parts of the bearing are not affected by such temperatures.israelkk You are not even close to accurate because you did not read my post. I said that normal was tough to define, meaning I did not intend to offer any normal value (don't you agree that "normal" depends on the appliion?) For sleeve bearings I gave some typical alarm and shutdown values, used at out plant. For antifriction bearings I gave a quote from a standard. (I never said anything about damage). If you think my quote from the standard is inaccurate thatn you have not read the standard. If you are saying that 180C is normal for all appliions of rolling bearings in electric motors you are off your rocker. ===================================== Engtips forums: The best place on the web for engineering discussions.Normal operating temperatures is probably from 0 degrees to 280 degrees. For appliions beyond or below, they are not normal and require special grease, seals, etc. If you are asking what is normal for the different appliions, you are asking a different question. If you know the answer, why ask?Another data point: For sleeve bearings EASA Large Electric Motor Handbook suggests the following: "Normal" 80C Alarm 90C Shutdown 100C When you apply a temperature limit also give consideration to where is the temperature being monitored. ===================================== Engtips forums: The best place on the web for engineering discussions.I would like to add it is a complex and perhaps somewhat controversial subject. I take no exception to anyone's opinion other than someone who throws around phrases like "not quite accurate" in response to a factual statement on the content of a standard. Diamondjim you say up to 280 I assume it is F. NLGI Group 1 General Purpose grease has a temperature range up to 250F doesn't it? That would seem to argue 250F as an max upper limit for actual bearing metal temperature. If temperature may be monitored on housing we have to reduce our limit another 15F or so to account for limitations of our monitoring. In our plant housing temperatures on most motor bearings are 130F or below. Occasionally after greasing some go to 180F or even 200F. If anything ever remained at these levels 180F200F by housing I would be concerned (my opinion). ===================================== Engtips forums: The best place on the web for engineering discussions.As is often the case, an innoccuous question can give rise to an extended thread of discussion. Whilst interesting in itself, this sometimes doesn't really answer the question asked. Each answers according to his own area of expertise. So no right and no wrong answer. its only possible to really answer in general terms to a nospecific question. Whats really needed is information on a specific type and class of bearing and a particular set of circumstances. With this I am sure everyone can make a considered contribution, and perhaps learn a little also! Until or unless the information is forthcoming then its perhaps better for etgbccc2003 to consult a bearing reference book such as supplied by the major bearing manufacturers such as SKF and others, and get a little more insight.jet1749, I beg to differ. I strongly disagree with the statement "so there is no right or wrong answer". Electripete offers and promotes considered and accurate opinions that are pertinent to his area of expertise as well as to the subject matter. If he does not know he always asks why. Take some time and look at his track record. It cannot be faulted. I am a grumpy Australian and have never met Electripete who I think is American. I sure like the way he handles himself in the many discussions he has participated in. etgbccc2003 probaby has learned a lot from his post. Maybe to stay out of the kitchenThanks for the kind words rnd. I enjoy your posts as well. My apologies to all I did not exactly handle myself well in earlier comments. All comments should be welcome and respected. ===================================== Engtips forums: The best place on the web for engineering discussions.Thanks a lot.
