Use with cylindrical roller bearings roller crown of symmetric spherical roller bearing high load carrying capacity, for example, strengthening tapered roller bearings and ball bearings, ball bearings, deep groove ball modified cars, or 70000CD series, rather than deep groove Bearings (single row radial) ball bearings, FAG bearings with high load carrying capacity, or because of the stress distribution, or because of a larger number of rolling elements may have a higher fatigue life. If the installation site license, optional size bearings freshman profile; if the radial dimension is limited, there is a wide range of circumstances, tapered roller bearings are widely bearings should be selected, if you can not use the wide bearing can be changed later with tapered roller bearings carrying capacity.
Of course, this high-quality steel used by the system, with more than tapered roller bearings FAG choose a more expensive load bearing capacity of the costs, but the machine is difficult to close, very difficult to remove the bearing, or in the mines, tunnels operating machinery The tapered roller bearings are used, maintenance is extremely difficult circumstances, sometimes I still want to consider.
Such as heating will reduce the strength of the material. After re-forming punch rivets willow, in order to improve the firmness of the blade and handle applications. Wearing parts, especially needles, tablets, set, speakers can not serve more butter and parts and repair worn parts such as prolonged use of restriction sites, will lead to a reduction in other mechanical life is short. In many types of material, easy to buy, the axis of waste currently available are based on our most 45 # steel shaft machining, mainly for the case of poor quenching conditions, the available oxygen, tapered roller bearing maintenance, earth oven heated to required parts are placed in brine red black hair, according to need.
Pulley fix the shaft key and keyway should ensure, as earlier, the transport can increase the same size as the key, otherwise it will affect the strength of the shaft, the shaft keyway for welding welding filler old key in the opposite direction keyway milling, keyway on the pulley inline (transition) method, will be good after blocking with countersunk screws tight cracks in critical attack.
Tapered Roller Bearings latest polymer ball bearings and bearing steel more than 80% pure traditional corrosion damage and chemical properties of lighter, tapered roller has developed the latest generation of polymer ball bearings. Select chemical moist, or more stringent requirements.
Outside the ring, must be in its entire circumference, and support the entire surface of the full width of the raceway. Solid support, and even necessary, to take full advantage of the tapered roller bearing capacity. Even support surface can be cylindrical or conical thrust bearing ring of the bearing surface, the aircraft can support. This means that the manufacture of the bearing support surface must have sufficient accuracy, the appearance should not have any grooves, holes and other defects of. Furthermore, the bearing ring fixed as necessary to prevent rotation in the bearing surface of the bearing effect. The ability to obtain satisfactory radial location and full support. Insufficient or incorrect fixed bearing ring usually causes damage to bearings and related parts. But if you need to install and easy removal, or non-fixed end bearing axial displacement, interference fit, should not be used. Some loose with the case of use, it is necessary to take special precautions to limit the wear and tear caused by creep.
