Bearing smooth smooth oil and grease selection and performance criterion

Smooth smooth oil and grease the bearings used in the process of common smooth agent, we to the bearing maintenance, smooth operation of bearing has a lot of help, such as to reduce the friction coefficient, etc. That we are choosing smooth smooth bearing oil and fat stop smooth demand understand what? China bearing network notice everyone, smooth agent what are the first to know bearing, secondly demand understand smooth agent performance options, and then stop understand smooth agent bearing the criterion is applied, the last stop choosing smooth agent. So bearing in smooth ability to ensure the most reasonable smooth effect. Smooth bearing commonly used agent: smooth oil - — Liquid, use the most common; Smooth fat - — Semisolid, common used in low speed; A smooth solid agent is mainly used as oil, grease additives, also can be used alone. The smooth oil performance options: viscosity - — Characterization of the size of the activities of the internal friction resistance in the liquid. Is one of the most important performance indicators, and a smooth oil mainly according to the choice. Oily - — Also calls the smoothness, polar molecules in characterization of oil adsorption performance of metal appearance. Oily, small friction coefficient. Condensation point - — Reflect the smooth oil low temperature performance. Flash point - — Reflect the smooth oil high temperature performance. Smooth oil selection criterion: 1, the pressure or work under impact, variable load condition, choose the high viscosity oil; 2, high speed, the persons to be of low viscosity oil, in order to reduce friction loss; 3, high working temperature, choose the high viscosity oil, landing due to viscosity rise with temperature. Smooth the performance of the grease choice: penetration - — Characterization of smooth fat thin consistency, similar to the oil viscosity; Drop point - — Characterization of smooth fat high temperature resistant performance. Smooth grease selection criterion: 1, the working environment of moisture, smooth choose calcium base grease; 2, high working temperature, choose sodium based smooth fat; 3, with water vapor and high working temperature, the persons to be smooth lithium base grease. Solid smooth agent: in order to avoid friction and maintenance appearance in a relative motion from damage and reduce the friction and wear of powder used in appearance and smooth thin layers of solid is called a solid agent. The use of solid smooth agent wide temperature range and good load-bearing ability is strong, prevent stick-slip, high vacuum resistance, radiation resistance, wide range of electrical conductivity, anti-corrosive, dustproof, so it is a special kind of smooth agent. Its defect is average friction coefficient is larger than smooth grease, energy loss is bigger; Can't cooling effect; The membrane process complex, etc.
