Overview

Traditional greases cannot operate effectively at high speeds owing to speeds, friction and temperature that is generated, as a result. As speed rises, assemblies warm up leading to grease being 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: N x D_m of the bearing to be lubricated.

N = the speed limit of the bearing in rpm and Dm = median diameter of the bearing in mm.

Setral Chemie high-speed greases allow for use at high-speed factors going up to 1.75 x 10⁶ and higher. Very often these greases have properties allowing them to reduce, at these high speeds, the noise from the bearings (low-noise greases).

Developed by Setral Chemie GmbH Germany for high-speed applications and bearings, Setral High-speed greases deliver unmatched performance in terms of lubricating life even under extreme temperatures and operating conditions.

With special lithium soap as thickener and special ester oils, Setral high speed greases provide superior corrosion and wear protection. Supplemented with an advanced additive package, the high-speed grease also possesses superior load carrying capability as well as ability to absorb vibrations and shock loads.
