In the design stage of bearing heater, the relationship between the lubrication technology and the reliability of the bearing heater is the most closely. The bearing, gear and seal used in the bearing heater are suitable for the lubrication of the machine parts, and even determine the life of the bearing heater. But from the perspective of the use of machinery and equipment selection of lubrication methods and lubricants, and its importance is no less than this.

However, on these issues, if the designers are not fully learn grip lubrication technology, it is difficult to consider the use of the temperature and the surrounding medium, loading conditions and equipment important factors to select the most suitable lubricant and lubrication method. If the bearings and lubrication methods are not suitable in the design stage, the bearing heater once made, it is very difficult to change to other forms. If you want to change, it is necessary to spend a high cost and a long time of transformation. In addition, on the proper value of coordination, the manufacture of surface roughness and assembly accuracy, often have to rely on experience, usually need to contact the manufacturing cost to take into consideration. In this regard, the plant has a lot of practical experience. Thus, it is necessary to check the lubrication relationship in the design of the lubrication technical personnel with rich experience.
