Fan Bearing Grease

Seasonal shutdown and start up when shutting your unit down for an extended period and before starting up after an extended shutdown always purge the fan shaft bearings with new grease.

Fan bearing grease.

Mistake 1 lubricating is based on time instead of condition. Able to handle light to moderate loads at high speeds this grease is often used on electric motor bearings for fans pumps and dryers. This property is known as the mechanical stability of the grease and is measured in standardized tests astm d217 and or astm d1831. Using the wrong type can clog up the bearings and ruin the fan oftentimes requiring a full replacement.

Some primitive fans like belt drive fans and very early electric models used grease packed babbit bearings. Stated as a number of hours l10 life indicates the life expectancy with 90 confidence that the bearings will meet the expectation. The oil to use in lubricating a ceiling fan s bearings is very specific. 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.

You want to find 10 15 or 20 weight non detergent motor oil. Mineral oil based grease derived from petroleum is more economical than synthetic oil. Oversized bearings can be lightly loaded and fail. Proper pillow block and seal selection help avoid bearing problems.

Greases that soften may leak from the bearing cavity. The higher the speed the more problematic they become. Induced draft products lubricate the bearings at least every three months. During rotation of a bearing the grease is mechanically worked and a change in consistency may result.

It offers a wide temperature range shear resistance corrosion inhibitors and extreme pressure lubrication. Fans and blowers are simple pieces of equipment yet require a lot of maintenance particularly for bearings. Typical ceiling fans like emerson s use oil immersed ball bearings mounted a race. Nlgi 3 is about the consistency of vegetable shortening.

Dow molykote g 0010 multipurpose bearing grease is a polyurea thickened material used for electrical motors water pump and fan bearings and dryers. Oil lubrication is preferred over grease for bearings. Fan bearing maintenance helps increase longevity and potential to reach the fan bearing s full l10 life. On some early models like turek friction drive fans a single ball bearing packed with grease was used to suspend the vertical rotor.

Bearings depend on grease to reduce friction levels. Nlgi 2 is about the consistency of peanut butter.
