SKF bearings after the installation is complete, in order to check for proper installation, run checks to. Small mechanical hand rotation, to confirm that the rotate smoothly. Check the project due to foreign body, caused by scars, indentation to seize up, because of the bad installation, mounting process arising out of the bad moments are not stable, owing to the clearance is too small, caused by installation errors, seal friction torque is too large, and so on. Without exception you can start power function.
Large machinery cannot be rotated manually, so no load starting immediately after cutting off power, mechanical idle, check for vibrations, noise, contact rotating parts, and so on, after you confirm without exception, into the dynamic operation.
Dynamic operation, starting from no-load speed, slowly raised to the conditions set forth in the rated operation. Things to check for in the commissioning, whether any unusual changes in sound, SKF bearing temperature, lubricant leakage or discoloration, and so on. If you find an exception, should immediately suspend the operation, inspection machinery and, if necessary, to remove the bearings checked.
SKF bearing temperature, generally according to the external temperature of the bearing seat to speculate. Uses of oil hole direct measurement of the temperature of the bearing outer ring is more accurate. Bearing temperature, from a running start rising, usually temperature-stable after 1-2 hours. Bad if the bearings are mounted, the temperature rises dramatically, exception occurred at high temperature. Too many reasons such as lubricants, SKF bearing clearance is too small, poor installation, sealing device too much friction. Occasions of high speed rotation, selection of bearing structures, lubrication is also the cause of the error.
