Under normal circumstances, apply mineral oil and synthetic oil lubrication of the bearings. Mineral base lubricant application up. At least request shall conform to DIN51501.
Better is the status of the contact surface is oil-film separation, long fatigue life of rolling bearings and higher abrasion resistance, should be chosen as possible high viscosity oil. But high viscosity is not exactly advantages, high viscosity lubricants friction greater at low temperature and the room temperature for oil and oil can be difficult. When choosing a lubricant that is taking into account the bearing reaches the maximum bearing life, but also to guarantee the normal supply of lubricant of rolling bearings.
Under normal operating conditions, simple lubricants can be used, but the better of anti-corrosion and anti-deterioration of oil. If the bearing heavy loads or low viscosity viscosity V1 v design, anti wear additives of oil should be used, use of EP additives and temperature has a great relationship. Its effect test of rolling bearings can be used to be.
When you select for high temperature lubricant, the main considerations of working temperature limit value and viscosity-temperature characteristic. Select the oil must be based on the nature of the oil. Often with oil bath lubrication, oil-spray lubrication of the bearing or lubrication supply lubricant. When oil bath lubrication is not used, must have for oil lubrication equipment to the bearing parts. Oil lubrication or commonly referred to as oil-bath lubrication of bearings, some penetrated in the oil. When the shaft in the horizontal position, if the bearing position fixed, then at half or all of the rolling elements should be penetrated in the oil. There is an asymmetric cross section bearings, because of its pumping effect, be provided with oil return holes or back to tank in order to ensure the circulation of oil. Under normal circumstances (bearing temperature does not exceed 80 ℃, pollution slight) changes oil cycle can be found under. Loading a small amount of housings with regular oil. During the run, due to the high temperature and abrasion particles pollution, advance for oil.
In the lubrication oil bearing after the adoption, into the collection tank, then returned bearing. Due to dirt in the oil can seriously shorten the service life of the bearing, therefore must filter. Circulating oil lubrication for oil content should be adapted to the condition of and bearing. Because the transmission effect of asymmetric cross section bearings (angular contact ball bearings, tapered roller bearings, spherical roller thrust bearings) than symmetric cross section bearings allow a greater oil flow through. Lubricant can take away a lot of tiny wear particles or heat.
