Tapered roller bearings after installation, to check for proper installation, operation check. Small machinery can be rotated by hand to confirm whether it rotates smoothly. Check project are caused by foreign bodies, scar, indentation to seize up, by poor installation, mounting bad moment of instability arising from processing, due to the clearance is too small, installation error, caused by seal friction torque is too large, and so on. Without exception you can start power operation.
Check first before cleaning the machine surface and perimeter of the disassembling bearing parts. Oil seals are very fragile parts, require careful disassembly, do not apply excessive pressure, then carefully check the oil seal and its surrounding parts of bad if you have symptoms, be sure to replace, bad oil seals will cause damage to the TIMKEN bearing and equipment downtime.
Power operation, starting from no-load speed, slowly raised to the specific conditions of rated operation. Things to check for in the commissioning, is there abnormal sound, changes in Taper roller bearing temperatures, lubricant leakage or discoloration, and so on. If you find an exception, should immediately suspend the operation, check the machine, if necessary, to remove the bearings check.
TIMKEN bearings turns the sound with the stethoscope to check, with strong metal noises, different sound irregular sound note exceptions. Due to poor lubrication, shaft or housing poor accuracy, bearing damage, intrusion of foreign bodies, etc.
When checking the TIMKEN bearings, don't let the bearing is exposed to contaminants or moisture environment. If the work is interrupted, the paper should be plastic or similar material of his machine.
In cases where that may perform checks without dismantling cleaning bearings without masking, picking oil solvent coating with a brush, then wipe dry with a lint free cloth or compressed air to dry (be careful not to let the bearing Assembly rotate).
Could not be cleaned and sealed bearings with cover or dust; just wipe the external surface. If TIMKEN bearings are damaged when replaced on demand. During regular maintenance periods of downtime to replace tapered roller bearings are more than due to damaged suddenly loss of selected economic
