Electric Motor Gearbox Grease

Nlgi viscosity grade is a rating of a grease s consistency.

Electric motor gearbox grease. 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. 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. However this thickener is incompatible with most other thickeners. Specifically designed for plastic and metal gears as found in many ebike motors.

Molykote pg 75 high quality german manufactured grease. Like other types of rotating equipment gearboxes rely on lubrication to reduce friction and provide cooling for optimal operation and life. Wipe grease from the pressure fitting clean dirt debris and paint around the grease relief plug. Nlgi 2 is about the consistency of peanut butter.

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. 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. Use of the wrong grease often leads to early electric motor failures. Nlgi 3 is about the consistency of vegetable shortening.

Instruct the motor rebuild shop on what grease to use and make sure the grease type is specified on new motor purchase orders. Some manufacturers don t recommend mixing one brand of polyurea with another. 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. Electric motors require lubricants with specific characteristics.

Among other factors motor and gearbox lubrication programs require understanding and a controlled lubrication approach. Able to handle light to moderate loads at high speeds this grease is often used on electric motor bearings for fans pumps and dryers. Mineral oil based grease derived from petroleum is more economical than synthetic oil. Good electric motor grease.

This will remove any hardened grease. Viscosity oil viscosity should be appropriate for the load and speed of the application at operating tempera ture. This prevents foreign objects from entering the grease cavity. A polyurea based grease is an excellent grease for electric motors.

Lock and tag out the electric motor. The typical mineral oil viscosity in an electric motor grease is in the range of 500 to 600 sus at 100 f. This will help to insure maximum protection and component life.
