Electric Motor Gearbox Grease

Able to handle light to moderate loads at high speeds this grease is often used on electric motor bearings for fans pumps and dryers.

Electric motor gearbox grease.

A polyurea based grease is an excellent grease for electric motors. Like other types of rotating equipment gearboxes rely on lubrication to reduce friction and provide cooling for optimal operation and life. Nlgi 3 is about the consistency of vegetable shortening. The majority of gearboxes tend to be highly loaded and as such require a lot from the lubricant to protect the machine s internal surfaces.

When a driven component is required to operate at a speed different than that of the attached motor driver a designer can choose from two basic power takeoff speed reduction increaser methods. Use of the wrong grease often leads to early electric motor failures. Specifically designed for plastic and metal gears as found in many ebike motors. Among other factors motor and gearbox lubrication programs require understanding and a controlled lubrication approach.

The grease consistency preferred for electric motors is normally nlgi 2 or 3 with a base oil viscosity of 100 150 cst 40 c. Nlgi viscosity grade is a rating of a grease s consistency. In this case you must make certain that the grease s viscosity is in line with what the gearbox needs to be properly lubricated as you do not want the viscosity to be too low to build a lubricating film. Nlgi 2 is about the consistency of peanut butter.

Remove the grease relief plug and insert a brush into the grease relief as possible. Gearbox manufacturers provide recommendations for the type of lubrication to be used and the typical lubrication intervals but the actual gearbox lubrication requirements depend on the environmental conditions the gearbox is exposed to whether it is. Lubriplate l0148 098 off white iso 9001 registered quality system iso 21469 compliant 100 cst electric motor bearing grease pack of 10 2 8 out of 5 stars 2 64 87 64. Suitable for long term lubrication low friction coefficient good lubricity at low temperatures compatible with plastics and elastomers molykote pg 75 is normally only available in 1000ml tins enough to do over 60 motors we now supply handy 30ml.

Electric motors require lubricants with specific characteristics. Molykote pg 75 high quality german manufactured grease. Instruct the motor rebuild shop on what grease to use and make sure the grease type is specified on new motor purchase orders. This will remove any hardened grease.

This prevents foreign objects from entering the grease cavity. Mineral oil based grease derived from petroleum is more economical than synthetic oil. Good electric motor grease. This will help to insure maximum protection and component life.

Lock and tag out the electric motor. Some manufacturers don t recommend mixing one brand of polyurea with another. The typical mineral oil viscosity in an electric motor grease is in the range of 500 to 600 sus at 100 f.
