Bearing as the major parts of the mechanical equipment, its type and lubrication type is also has a lot of, today China bearing network mainly introduces relevant insert spherical bearing lubrication type. Insert ball bearing lubrication, there are two main types of a lubrication method is called oil mist lubrication, the other is a minimal quantities of lubricant, brief refers to a handful of lubricating oil to satisfy the requirement of the insert spherical bearing lubrication. Oil mist lubrication is to become oil mist lubricating oil in the oil mist generator, through the oil mist lubrication of bearings. Because oil mist in the set-contained spherical bearing homework appearance agglutinate oil drops, actually insert ball bearing unit is still maintained a thin oil lubrication condition, this gesture can extend the set-contained spherical bearing life spans. China bearing network warm prompt use the lubricating way should pay attention to the following two points: 1. Oil viscosity selection generally should not be higher than 340 mm/s ( 40 degrees) Because of the high viscosity will reach atomization effect. 2. Lubrication of oil mist may partially with the degradation of air, will pollute the environment. Oil and gas separator if necessary to collect the oil mist, might choose to remove exhaust ventilation equipment. When bearing rolling body linear velocity is very high, often USES oil mist lubrication, to avoid excessive because other lubrication oil, oil increased the internal friction increases set-contained spherical bearing operating temperature. General oil mist pressure is about 0. 05-0. 1mbar。
