Using the wrong type can clog up the bearings and ruin the fan oftentimes requiring a full replacement.
Fan bearing grease.
Nlgi 3 is about the consistency of vegetable shortening.
During rotation of a bearing the grease is mechanically worked and a change in consistency may result.
Nlgi viscosity grade is a rating of a grease s consistency.
Oversized bearings can be lightly loaded and fail.
Fan shaft bearing maintenance ball bearings.
Oil lubrication is preferred over grease for bearings.
Mistake 1 lubricating is based on time instead of condition.
Dow molykote g 0010 multipurpose bearing grease is a polyurea thickened material used for electrical motors water pump and fan bearings and dryers.
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.
This property is known as the mechanical stability of the grease and is measured in standardized tests astm d217 and or astm d1831.
Some primitive fans like belt drive fans and very early electric models used grease packed babbit bearings.
You want to find 10 15 or 20 weight non detergent motor oil.
The higher the speed the more problematic they become.
Stated as a number of hours l10 life indicates the life expectancy with 90 confidence that the bearings will meet the expectation.
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.
Bearings depend on grease to reduce friction levels.
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.
The oil to use in lubricating a ceiling fan s bearings is very specific.
On some early models like turek friction drive fans a single ball bearing packed with grease was used to suspend the vertical rotor.
Greases that soften may leak from the bearing cavity.
Typical ceiling fans like emerson s use oil immersed ball bearings mounted a race.
Fans and blowers are simple pieces of equipment yet require a lot of maintenance particularly for bearings.
Proper pillow block and seal selection help avoid bearing problems.
Able to handle light to moderate loads at high speeds this grease is often used on electric motor bearings for fans pumps and dryers.
Fan bearing maintenance helps increase longevity and potential to reach the fan bearing s full l10 life.
It offers a wide temperature range shear resistance corrosion inhibitors and extreme pressure lubrication.
