In certain applications, ball bearings are required to operate in aggressive environments, causing recurrent failures and therefore high operating costs. These failures can be due to corrosion or pollution by particles that penetrate the bearing.
This is the case, for example, in production facilities in the food industry, which are often cleaned with hot water under pressure or with solvents, which greatly increases corrosion and grease leaching.
Jesa has therefore undertaken, within the framework of its innovation projects and with a specialized partner, to develop and validate a solid lubricant, commonly called "solid oil", which is a polymer material saturated with synthetic oil.
This compound can easily be introduced into a ball bearing and heated so that the lubricant hardens and becomes a solid and porous matrix structure that will occupy all the available space inside the bearing around the rolling elements and the cage. This high fill rate gives JESA bearings excellent protection against moisture and dust while providing a very high level of micro-lubrication due to the amount of oil from the porous matrix.
This solution offers many advantages and is particularly recommended for bearings operating in an aggressive environment or where re-lubrication is difficult due to accessibility. The solid oil allows to increase drastically the lifetime of the bearings and consequently to reduce the maintenance costs. The compound is also InS-H1 certified and can therefore be used in many industries such as food, beverage, pharmaceutical, medical or textile.
