In the General case, grease fill volume in a single direction thrust ball bearings, always exceeds the amount of directly involved in the practical needs of lubrication, and bearing cover on the cage cavity, and rolling the perimeter to form a contour. In this process, due to the extra grease resistance, bearing temperature rise quickly. Although most of the excess grease in the early running was out, and squeezing roller attachment grease is still likely to be between turning the rolling to the Raceway. Those bearing the initial stage of operation, most of the grease quickly (less than a minute) out of raceways, are stacked in the grease in the rotation with single direction thrust ball bearings while loop, little being discharged one after another. When the bearing temperature continued to rise, up until the excess grease is discharged, may be called grease collection phase, according to factors such as the quality of grease in the bearings, fill, this period can last a dozen minutes, or even hours.
First, when single direction thrust ball bearings after installation is complete, please try first hand shaft bearing Assembly, observation bearing one of the following situations:
1, rotating and fixed parts of the system are anti-folders or interference;
2, AX steady rotation of the rotating system is flexible and no block, no loose, the pills before and after channeling phenomenon;
3, the reliability of the bearing inner ring side face conflict on the shaft end face, if there are any gaps;
4, observation of lubricating oil supply or circulation is normal, sealing device-gap is symmetrical, the fastener is loose.
Second, to check the rotation of the rotating system of single direction thrust ball bearings, axial spacing accuracy with precision, operational clearance, as well as other necessary checks.
Finally, after these checks confirm that all is well, you can begin using, but if you find any abnormal signs, you should immediately stop using and troubleshooting.
When installing a single direction thrust ball bearings, you should verify the shaft and axle center line vertical. By moving the dial fixed on the tank shell surface, touch the top of the table in the bearing ring raceway top rotating bearings, boundary observation indicator pointer, pointer to swing, note the shaft and axle centre line is not vertical. When the tank shell holes deep, thousand tables can also be used to lengthen the first test.
