Oil-bearing installation knowledge

Oil-free self-lubricating bearings: it is based on steel base, oil-bearing intermediate layer sintering spherical bronze powder, surface rolled the mixture of PTFE and lead made. It has a low coefficient of friction, wear and corrosion-resistant oil-free self-lubricating and long service life, use it to reduce costs, reduce noise, prevent sticking, slippery. It is widely used in various mechanical sliding parts such as printing presses, textile machines, hydraulic truck, tobacco machines, pharmaceutical machinery, fitness equipment, micro-motors, automobiles, motorcycles and the like. Its installation process need to have little knowledge of the following:
1, the axis should be determined, with the surface of the shaft case whether there injured, projections, etc.
2, if there is dust or sand attached to the bearing surface of the shell mold.
3, although minor bruises, projections, etc., if you want to remove the oil grindstone or fine sandpaper.
4, in order to avoid scratches when loading capacity, surface of the shaft and the shaft housing should wipe a small amount of lubricating oil. To bearing is mounted on the axis of the inner ring to be biased to the bearing mounted on the bearing housing, it shall be in the outer ring biased. To bearing biased, so be sure to pay attention to the power of vertical and uniform down, partial play will make the bearing injuries. To do this absolutely avoid bias fight.
5, oil-free bearings and seal retainer plate and must not biased. Use a hammer and casing installation method is a method commonly used in general, because it will damage the bearings, so do not directly beat. Be sure to FIG. Generally, the sleeve in the middle and beat into the medium. Hammers should be lightly beat. On the mechanical structure, the inner and outer ring are a tight fit, you should use the pad, make sure the power is applied to the inner and outer ring simultaneously pushed into it. If only the inner ring into the adding force, the force will be referred ball and pressed into the outer ring, therefore, it can cause scars in the orbital plane. To a large margin of the bearing mounted on the shaft, the clean oil in the bearing is heated to 80 to 90 degrees, the inner diameter of the inflating installation method, is widely used.
6, the hardness of the bearing, there is reduced due to overheating of the consideration, therefore, must not exceed 100 degrees. In this case, the bearing must be used to wire suspension, or placed on top of a wire link, the support plate, not placed in the bottom. Bearing reached the desired temperature (100 degrees), it should be immediately removed from the tank, quickly set into the shaft, bearings will shrink as the temperature dropped, and sometimes between the shaft shoulder and the bearing end face gap will, therefore, need to use the tool, to the bearing axis pressed.
