 Large quantities TIMKEN one-way bearing production, commonly used model, the sample file block by model adjustment process system; usually use the scale on the machine in a single piece and small batch production, or utilization to adjust. The contents of the adjustment due to the complexity of the workpiece for a simple surface (such as the outer cylinder), usually only adjust the position relationship of the shaping movement; complex surface (such as the spiral surface, involute), we must adjust the forming speed relationship of the movement. Therefore, the adjustment TIMKEN one-way bearing error is caused by a variety of factors. 
 TIMKEN one-way bearing measurement error should be less than 10% of the tolerance. General measurement error exploits the difference between 10% to 33%, with the tolerance level of increase, the greater the error proportion, that is, smaller the tolerance the higher the error of the proportion of TIMKEN one-way import bearings tolerance of the IT5 above, it is difficult to achieve 10%. Measurement error does not mean that the test tolerances can be relaxed, 10%, but to give a certain margin of safety to ensure user acceptance in accordance with the standard. 
 TIMKEN one-way bearing parts processed in each process, in order to get the bearings machined surface the size, shape and location accuracy, he will have to machine tools, fixtures and tool adjustment, any adjustment will inevitably bring a certain degree of error. Often require different production volume and processing accuracy of the bearing parts machining, the adjustment method used is also different. 

 The raceways sound TIMKEN deep groove rolling element ball bearing swivel raceway rolling inspire a smooth and continuous noise, to draw attention only when great when its SPL or tone.

 Installed NSK angular contact ball bearings also need to check which 

 There are strong metal noise, abnormal sound, irregular sounds and other description of an exception. The reason for poor lubrication, poor shaft or bearing accuracy, bearing damage, dust and debris. NSK angular contact ball bearings to turn the sound with a stethoscope to check. 
 Many users there is this problem NSK angular contact ball bearing device after will not be checked and this has led to NSK angular contact ball bearings in the operation of the process. NSK angular contact ball bearing operation and to examine what matters it? 
 In order to check whether the device correctly, NSK angular contact ball bearing device end. To operate check. Small mechanical hand rotation, to determine whether the rotation smooth. Nick, indentation caused by ill-functioning inspection items due to poor installation, the device processing bad torque instability, the clearance is too small, the device error, the seal friction torque is too large and so on. If there is no exception, you can start the power operation. 
 So cut off the power immediately after the no-load start large-scale machinery can not manually rotate. Machinery idling, check for vibration, noise, rotating parts in contact with confirmation without exception, to enter the power operation.

 From no-load low-speed power operation. Slowly raised to the conditions stipulated in the rated operation. Inspected items in commissioning for any unusual sound, bearing temperature changes, lubricant leakage or discoloration. If abnormal, should be immediately discontinued operation, check the mechanical, if necessary, to remove the bearing check.
