Fan Bearing Grease

Typical ceiling fans like emerson s use oil immersed ball bearings mounted a race.

Fan bearing grease.

Stated as a number of hours l10 life indicates the life expectancy with 90 confidence that the bearings will meet the expectation. Oversized bearings can be lightly loaded and fail. Able to handle light to moderate loads at high speeds this grease is often used on electric motor bearings for fans pumps and dryers. The higher the speed the more problematic they become.

Nlgi viscosity grade is a rating of a grease s consistency. Mistake 1 lubricating is based on time instead of condition. Induced draft products lubricate the bearings at least every three months. Proper pillow block and seal selection help avoid bearing problems.

Greases that soften may leak from the bearing cavity. On some early models like turek friction drive fans a single ball bearing packed with grease was used to suspend the vertical rotor. Nlgi 3 is about the consistency of vegetable shortening. The oil to use in lubricating a ceiling fan s bearings is very specific.

Bearings depend on grease to reduce friction levels. You want to find 10 15 or 20 weight non detergent motor oil. Fan shaft bearing maintenance ball bearings. It offers a wide temperature range shear resistance corrosion inhibitors and extreme pressure lubrication.

Dow molykote g 0010 multipurpose bearing grease is a polyurea thickened material used for electrical motors water pump and fan bearings and dryers. During rotation of a bearing the grease is mechanically worked and a change in consistency may result. This property is known as the mechanical stability of the grease and is measured in standardized tests astm d217 and or astm d1831. By avoiding three common mistakes when greasing bearings you can predict the right time to grease know how much grease to apply and be confident in the bearing s overall health.

Fans and blowers are simple pieces of equipment yet require a lot of maintenance particularly for bearings. On the same note lubricant systems in ball bearing fans which are based on grease channeling can fail slowly over time causing a gradual increase in noise particularly at high temperatures. Fan bearing maintenance helps increase longevity and potential to reach the fan bearing s full l10 life. Mineral oil based grease derived from petroleum is more economical than synthetic oil.

Oil lubrication is preferred over grease for bearings. Using the wrong type can clog up the bearings and ruin the fan oftentimes requiring a full replacement.
