This is a solid-free lithium complex grease, and there is a reason for this. Grease compatibility is an issue because of what can happen when two incompatible greases are introduced to each other. This is important to consider when refilling a reservoir that already contains grease. Lubrication grease is a mixture of oil and soap or another On the other hand, lithium complex is the most common thickener on the market, making up nearly 60 percent of the greases available in North America. Mineral/PAO. Safe to say that I won't be letting either one touch my machine as they aren't using the grease that is recommended per the tech manual. The Transition To Lithium The continued changes in the automotive market directly impact the industrial grease market. 4. These properties have made polyurea greases a number one choice for sealed-for-life bearings, ball bearings, constant velocity joints (CVJ), and electric motors applications. Bearing Greases, NLGI Grade: 2, Polyurea Grease Thickener. One uses blue waterproof grease on all the zeros and the other one uses another amber grease (not polyurea or lithium complex). Suited for: Its recommended for off-road equipment, Farm vehicles, commercial and fleet applications, and steel mills. Use bearing grease to add lubrication to new bearings or to replenish grease on older bearings where the lubrication has dried up or worn away. Which type are you guys using and why. Lubrication grease is a mixture of oil and soap or another thickener. Polyurea can also be used in extreme temperatures. The biggest advantage of polyurea is that the ratio of oil to thickner is greater in polurea than other greases, so a given volume of polyurea will lubricate longer than other greases. We did a project last year and installed 20 new motors. We used Unirex ep grease for our motor and fan bearing and unirex is lithium base. The new teflon bearings ride on the stock Orion baseboard.

Polyether polyamine is for polyureas, while polyetherpolyol is for polyurethane. Increased durability and shear stability versus conventional polyurea greases Lithium grease has shown to impart the advantages of high adherence, non-corrosiveness, and moisture resistance making them compatible with several applications . Lithium grease. Calcium sulfonate greases exhibit greater shear stability than lithium complex greases. From a grease consistency the Polyrex EM is a much smoother grease vs Lucas that is much tackier Polyrex EM is more creamy than tacky. Calcium 12 Hydroxy. Excellent high temperature performance. Oil bleed (the amount of oil that comes out of a grease during storage) should not exceed 5%, and keeping this to about 1% 2% is preferable for good lubrication. Polyurea is 4x stronger and 98% more flexible than Epoxy. Aluminum Complex. Both systems are made up of two components, and the curing mechanism is by co-reaction. Base oil compatibility chart. Excellent thermal and oxidation stability. Lithium Complex grease, the most popular choice in the marketplace, plays well with everything except Clay (Bentonite Clay), Barium Complex, and conventional Polyurea Calcium Sulfonate grease , which exceeds lithium complex grease in multiple key performance parameters, also has the advantage of broad compatibility with many other types of grease. Perhaps one of the most common inadvertent mixing of greases occurs when a Lithium Complex grease, commonly specified or used as a factory fill in bearings in fans and pumps, meets up with a Polyurea grease, often used in electric motors. Very good resistance to water washout and water spray-off. Bentone (Clay) Calcium Stearate. manchester iowa city limits; scottish jewelry for sale; reindeer template printable There is no strong odor from Polyrex EM and to my knowledge it's non toxic for the most part it's rated for operation between -20C to 350C.
