What kind of Grease do you use on a spindle?
Polyurea or (multipurpose) grease —This type of grease is good for parts that reach a high temperature, as this is a “high temp grease.” Machines that have spindles or rotating grooves can get very hot and a polyurea grease won’t break down as quickly as other types of grease.
What kind of grease to use on potted motor?
You may have to get what is called Sew Retro grease which is close to the original formula you can get. The lubricant you need has to have the right melting point in order to work well and keep your potted motor lubricated.
What do you mean by multi purpose grease?
The term “multi-purpose” is quite popular for greases on the market and usually relates to some common additives and the viscosity of the base oil. Many of these grease types have extreme-pressure (EP) additives and a base oil viscosity of 220 centistokes (cSt).
What’s the difference between oil and Grease in a motor?
Grease, on the other hand, is a semi-solid lubricant that requires some heat to melt down to a liquid before it can flow to different parts. Also, grease stays where it is put, like on bearings, and doesn’t usually leak out like oil will. Another difference is that oil is easier to drain, remove and clean up.
What are the qualities of electric motor grease?
The following is a list of qualities of a good electric motor grease: Good channeling characteristics. NLGI Grades 2 to 3. Base oil viscosity of an ISO VG 100 to 150 or more specifically 90 to 120 cSt at 40°C. High dropping point, 400°F minimum.
Why do you have to use the same grease for every bearing?
Therefore it is important to use the same grease or compatible substitute throughout the life of the bearing. Motor Casing Full of Grease – If the grease cavity is overfilled, and high pressure from the grease gun is applied, the excess grease can find its way between the shaft and the inner bearing cap and press into the inside of the motor.
Polyurea or (multipurpose) grease —This type of grease is good for parts that reach a high temperature, as this is a “high temp grease.” Machines that have spindles or rotating grooves can get very hot and a polyurea grease won’t break down as quickly as other types of grease.
How to choose the best grease for your heavy equipment?
NLGI stands for the National Lubricating Grease Institute and is the institution that certifies grease. Grease can range from NLGI #000 to NLGI #6, but the most common is NLGI #2 because it can be used for a wide temperature range. Read: How to Prepare Your Heavy Equipment for Summer.
