inches) with the total bearing’s width (in inches) or height (for thrust bearings). The product of these two parameters along with a constant (0.114, if inches are used for the other dimensions) will give you the grease quantity in ounces.

There are a few ways to calculate the relubrication frequency. Try Noria's bearing grease volume and frequency calculator . Some methods are simplified for a specific type of application. For general bearings, it’s best to take into consideration several more variables besides the operating and environmental conditions. These include: Temperature – As the Arrhenius rate rule indicates, the higher the temperature, the quicker oil is going to oxidize. This can be taken into practice by shortening the relubrication frequency as higher temperatures are anticipated. Contamination – Rolling-element bearings are prone to three-body abrasion due to their small film thickness (less than 1 micron). When contamination is present, early wear can result. The environmental contaminant types and the likelihood for contaminants to enter a bearing should be taken into consideration when defining the relubrication frequency. Even the average relative humidity can be a point of measure to indicate water contamination concerns.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
