Accordingly, bearing manufacturers have provided detailed advice for estimating lubricant type, volume and frequency requirements. Frequency Calculator. SKF Explorer steel/steel plain bearings, virtually maintenance-free + The basic rating life for SKF Explorer steel/steel plain bearings can be calculated using G h = b 1 b 2 b 3 b 5 [5 / (p 0,6 v 1,6 )] It’s amazing how such a common task is also plagued with ways to make mistakes, such as overgreasing, undergreasing, overpressurizing, greasing too frequently, greasing infrequently, using the wrong viscosity, using the wrong thickener and consistency, mixing multiple greases, etc. When contamination is present, early wear can result. In this calculator, the bearing geometries for more than 2,700 bearings including: SKF, NTN, Cooper, and Dodge are available. Once the required grease volume has been calculated, you will need to determine how often to apply that amount of grease. Source #2 Bearing interface damping between the bearing rings and housings or shaft respectively. The formula is as follows: Re-lubrication Amount of Grease (g) = 0.005 * Bearing Outside Diameter (mm) * Total Bearing Width (mm). * The SKF formula for volume is directly proportional to the product of D*B (even though bearing volume would be more closely proportional to D^2*B). hbspt.cta.load(3951034, 'c99217f3-09e7-4751-bc3a-7739dac44a0e', {}); Bennett Fitch is the director of product development and lubrication program development (LPD) services for Noria Corporation.

Yeah I have the SKF apps. SKF Cooper split units . While these factors play a role in calculating the relubrication frequency, often the environment is too contaminated, the likelihood of contaminants entering the bearing is too high and the resulting frequency is not enough. They can be quite handy at times. By using our site, you consent to cookies. If the cost of using more grease is less than the risk of bearing failure, then purging grease might be the best option. Figure 14: Starting points indicated for example. The unit system can be set only on the ‘Select bearing’ page. A good bearing database is essential in my view. They can be quite handy at times. This approach pro-vides the volume in grams per hour. In my experience the CSI database is the most extensive. Using basic and advanced search criteria, including part numbers, you can find the frequencies of tapered, ball, cylindrical, spherical and thrust bearings. The cage frequency is the only sub-synchronous frequency of the bearing, meaning that it is the only frequency falling below the rotational speed of the bearing.

The amount of grease during each relubrication procedure can usually be calculated by simply looking at a few bearing parameters. The in-formation required is generally easy to obtain. Sign-In » Unfortunately, much of the information required is not always readily available, so the use of … While all these greasing mistakes can be discussed in length, calculating the grease quantity and how frequently each bearing application needs to be greased is something that can be determined from the very beginning using known variables about the bearing’s operating conditions, environmental conditions and physical parameters. Welcome to medias Please select your country. * The EPRI curve provides a non-linear function of d which is approximately the required d^2, but does not account for B which varies. The program, which delivers the information straight to your iPhone or iPad, is fast, simple and easy to use. - RITEC Bearing Frequency Calculator is a free tool provided by RITEC. In general, it’s advisable to grease more frequently when bearings are closer to a vertical position. With the aid of the bearing frequency calculator, you can determine this by inputting the geometrical data. Too Much or Too Little Lubricant: Which Is the Bigger Problem? The cage frequency will almost always fall between 35% and 45% of the bearing rotational speed. Runtime – Running 24/7 versus sporadic use, or even how often there are starts and stops, will have an impact on how quickly the grease will degrade and how effectively the grease will stay in the key lubrication zones.

Vibration analysis of rotating machinery is common practice in predictive maintenance programmes. to support frequency spectrum analysis. Grease is a combination of approximately 85% oil (mineral or synthetic) and 15% soap or thickener. A one-time user registration is required for access. You will need to know the internal geometry of the bearing, which can be obtained from the manufacturer. You can easily write your own calculator using Excel. In practice, however, it is unlikely that this type of contact is occurring perfectly, which can lead to small frequency errors. Source #4 Material damping due to Hertzian deformation of the rolling elements and raceways. It is easy to apply and retain within the bearing housing and can also function as a seal to protect the bearing. NDB bearings provide a charted, consistent method for defining paths aircraft can fly. SKF Engineering Calculator | SKF A spectrum analyzer measures the amplitude of an input signal versus frequency within the full frequency range of the instrument. Some methods are simplified for a specific type of application. This involves taking a grease gun filled with grease and pumping it into all the grease Zerks in the plant. For open bearings the best way to determine the re-lubrication interval is to use the SKF DialSet re-lubrication interval calculation program, which you can download from this site. The SKF formula method is frequently used by multiplying the bearing’s outside diameter (in inches) with the total bearing’s width (in inches) or height (for thrust bearings). It shows whether components are in healthy shape or suspect to anomalies. - Using a different manufacturers' data, for the same bearing number, may yield an errouneous value. Below is a chart of these correcting factors and how they operate together. This can be taken into practice by shortening the relubrication frequency as higher temperatures are anticipated.
