Attention to the use of SKF bearings
1, Keep SKF bearing and its surrounding environment clean, and even enter the tiny invisible dust of the bearing, will increase the wear, vibration and noise of the bearing.
2, Use the installation carefully, so that the powerful stamping is not allowed to hit the bearing directly with a hammer
3, Appropriate and accurate installation tools to use the use of special tools, as far as possible to avoid the use of cloth and short fibers, such as four, to prevent corrosion of bearings bearings directly by hand selection, fully wash hands sweat, and then coated with high-quality mineral oil in the rainy season and summer especially pay attention to rust
However, under certain special operating conditions, bearings can obtain a longer life than conventional calculations, especially under light load conditions. These special operating conditions are when the rolling surface (rails and rolling parts) is an effective lubricating film to separate and limit contaminants that can cause surface damage.
Selection of grease
Lubrication has a very important effect on the operation and life of SKF bearings, here to briefly introduce to you the general principle of grease selection grease is made of base oil thickener and additives, different types and the same type of different grades of grease performance is very different, the allowable rotation limit is different, be sure to pay attention to in the selection
The performance of grease is mainly determined by the base oil, generally low viscosity base oil is suitable for low temperature and high speed, high viscosity is suitable for high temperature and high load thickener is also related to the lubrication performance, the water resistance of thickener determines the water resistance of grease. In principle, different brands of grease can not be mixed, and even the same thickening agent grease, due to different additives will bring bad effects on each other.
Installation and disassembly of SKF bearings
When installing, do not directly hammer SKF bearing end face and non-stressed surface, should be pressed block sleeve or other installation tools to make SKF bearing uniform force, do not install by rolling body power transmission. If the mounting surface is lubricated, it will make the installation more smooth. If the fit is large, the SKF bearing should be installed as soon as possible after heating to 80~90 in mineral oil. Strictly control the oil temperature is not more than 100 to prevent the tempering effect hardness reduction and affect the size recovery. When encountering difficulties in disassembly, it is recommended that you use the disassembly tool to pull outward while carefully pouring hot oil on the inner ring, the heat will make the SKF bearing inner ring expand, so that it is easier to fall off.
