High speed grease

High velocity bearings grease

Maintaining high-velocity bearings—whether in skateboards, scooters, or machinery—requires a strict, regular routine of cleaning, inspection, and precise lubrication to prevent overheating and premature failure. Key practices include using specialized thin lubricants, avoiding water, and ensuring bearings are not over-filled with grease

Range of greases allowing operation at very high speeds, in particular in systems where oil greasing is not practicable. Traditional greases cannot operate effectively at high speeds. With speed, assemblies warm up and standard grease can be ejected, finally resulting in breakage of the equipment.

High-speed greases are formulated with special thickeners and oils allowing them to approach the functionality of oil while keeping the sealing properties required in this type of mechanism. One of the parameters to take into account is the speed factor. High-speed greases are formulated to resist sling-off and to stay in place despite high rotational speeds and thus prevent breaks in the lubricating film.

Aside from our suggested low base oil viscosity, another grease property that impacts its channeling characteristics is the thickener type. The thickener in a grease is commonly referred to as the sponge that holds the oil. The structure of the fibers in the thickener can affect certain grease properties, such as channeling, bleed, dropping point and overall consistency. Some grease thickeners have long fibers, while others have short fibers.

The speed factor is a term that helps define the relationship of the speed at which a bearing rotates with the size of the bearing. There are two main ways to calculate this factor. The first is known as the DN value, which uses the bearing inner diameter multiplied by the speed at which it rotates. The second method is known as the NDm value. This uses the bearing’s median size, also known as the pitch diameter, and the rotation speed to calculate the speed factor.

The speed factor can help you determine a variety of lubricant properties, which you can then utilize to select the proper lubricant. Among these properties would be the viscosity of the oil and the National Lubricating Grease Institute (NLGI) grade of the grease for the application.

MOLYLUB’s range of high speed greases with low base oil viscosity and select thickeners have the ability to maintain desired film thickness even at high RPM’s.

Synthetic high performance grease with high speed index for high speed applications and spindle bearings. Molylub Supra high speed bearings grease provides long term lubrication even under extreme temperatures and operating conditions. Synthetic PAO base oil in Molylub Supravit ensures extended service life. Smooth structure of Molylub Supra ensures minimal internal friction translating to reduced start-up torque and therefore less temperature build up. Molylub Supravit provides superior corrosion protection as well as excellent resistance to alkaline coolant attacks. Extreme pressure additives offer good lubrication under medium to high loads and vibrations.
