individual transport vehicle localization
In the past, such as a car unit, which is unwilling to be able to achieve in the freight train . Information and data , it is best to use satellite technology supply , can only be an independent , self-sufficient energy supply systems . "This should be grateful for FAG Group invention Generator Sensor Bearing , via satellite communications has opened up new possibilities for optimizing logistics and freight transport , and to improve traffic safety ," angular contact bearing, FAG electromechanical systems commander said. Sensor integrated in the bearing not only record data about the conditions of axle bearing itself, such as wear or overheating also recorded . Generator Sensor Bearing FAG determining and monitoring features, speed, temperature , mileage and noise , so that conclusions about the condition of the wheels , bogies and even railway track . This means that a good combination of the two can . Evaluation of data records is also the rotating thin section bearing and optimize the entire transport and cargo flow and trucks available space control , positioning, tracking and calculating utilization costs , considering the loads, the number of axes , time and distance . Great innovation , transport and logistics is self-sufficient in energy production by connecting the motor bearings and FAG send sensor data sensor and the respective vehicle units and high-level information form the new control system . FAG train control system is in proximity to rail guidance system is an important step , is currently undergoing preliminary testing and Finnish track. In addition to GPS data acquisition. In other words, individual transport vehicle localization, the entire logistics chain review - transporting goods through satellite tracking , this knowledge , the current way to make optimal use of the scheduling and container freight vehicles . Germany FAG Bearing Group not only provide you with quality FAG bearings, can also provide you with the module inheritance, measurement technology, power transmission and control , as well as internally developed computer program enables our engineers to direct a global user-oriented design full transmission system and the required bearing support program . Chinese distributor FAG FAG Bearings you are welcome to inquire the price .

Schaeffler Group President and CEO Dr
Schaeffler Group Appoints New Chief Financial Officer
We learned from Germany FAG thin section bearing Group, March 18, 2009, the Schaeffler Group Appoints New Chief Financial Officer Klaus Rosenfeld as President. Mr. Klaus Rosenfeld Dresdner Bank AG board member since 2002, is responsible for Dresdner region's financial control, business investment. Schaeffler Group President and CEO Dr. Yu Ergen said Claudia Strobel Senfei De sir "Claudia Strobel Senfei De, we have listened to the views of many angular contact bearing members and experts acknowledged, you want to Schaeffler Group this challenging financial environment to grow, it must Schaeffler Group's financial management to make greater contributions to the cause, you understand? "replied Mr. Klaus Rosenfeld quite sure Before February 18, has informed the German FAG Bearings Group's former chief financial officer Thomas Hetmann (46 years old) will leave the company after the transfer of its duties. Schaeffler Group thanked Mr Thomas Hetmann the hard work and dedication to the company.

Rolling technical standards and precautions
1, with the use of the bearing and shaft hole basis, bearing and housing system using the base axis. Bearing Size Tolerances and rotation accuracy is obtained by GB307-84 requirements.
2, with the bearing with the journal and the bearing housing bore by GB1031-83 requirements, the journal roughness Ra value of less than 1.6μm, bearings inside the hole roughness Ra value of less than 2.5μm.
3, with and ZGCr15 steel GCr15 bearing rings and rolling midnight, its rings and roller hardness value should be 61 ~ 65HRC; using GCr15SiMn and ZGCr15SiMn steel, the hardness value should be 60 ~ 64HRC. Hardness inspection method and the same part by the uniformity of hardness JB1255 requirements.
4, check the bearing radial clearance and axial clearance shall comply with the requirements of GB4604-84.
5, the bearing inner and outer ring raceway should be no peeling, severe wear, inner and outer rings are not allowed to have cracks; ball should be no wear, cage without serious distortion, rotation no abnormal noise and vibration, stop should be gradually stopped.
6, C-level tolerance for tapered roller bearings, roller and ring raceway contacts accuracy, under the action of a certain load, check for coloring, contact marks should be continuous, rolling contact length of not less than 80 picture-line.
Bearing life is associated with manufacturing, assembly, use all closely related, must make every link in order to make the bearing in the best operating condition, thus extending bearing life.
1, the shaft and the bearing housing tolerances choice and control: bearings are pressed into block after no sense should be flexible rotation. If significant rotation is not flexible, it indicates that the shaft size is too large, tolerance to downward. Such as bearings pressed into the shaft turned by hand obvious "imperfections" sense, it may be too much tolerance of the shaft or shaft roundness bad. So good control shaft and the bearing housing tolerance should also control the roundness, many domestic manufacturers only tolerance control, no roundness control.
2, the bearing assembly methods: Because the bearings are precision products, such as improper assembly is very easy to damage the bearing channel, leading to bearing damage. Bearing in the assembly should have a dedicated mold and can not beat the pressed into the shaft when the force only a small circle, the circle can only push a large circle force. Assembly requires the use of pneumatic or hydraulic, press-fit upper and lower mold to remain outside the state level, if inclined bearing channel will lead to damage due to power, leaving the bearing guide ring.
3, the assembly to prevent foreign bodies: Bearing mounted to the rotor can easily do balancing balancing generated when the iron filings into the bearing, so it is best to do before loading the bearing dynamic balancing. There are some manufacturers in order to facilitate assembly, the assembly in the bearing chamber coated with some oil or grease lubricant effect, but the operator is often difficult to control the amount, if the oil or grease in the bearing chamber accumulates more in the bearing rotation is easily along the shaft into the bearing. Bearing chamber preferably not coated with oil or grease, such as non-coated bearings shall not be have to control indoor accumulates.
4, paint rust prevention: paint rust characterized by multiple in sealed-type motor, motor in the assembly sounds good, but put in the warehouse for some time, the motor becomes very abnormal sound, remove the bearing severe rusting. Many manufacturers will be considered a bearing problem, through our continuous publicity, and now the motor plant has been realized mainly insulating paint problems. The problem is mainly because the insulating paint out of the volatile acidic substance at a certain temperature, humidity, the formation of corrosive substances cause corrosion of the bearing channel bearing damage. The problem can only be a good selection of insulating paint, and after a period of time after drying ventilation assembly.
