Do daily maintenance analysis roller bearing details
A touch
NTN Bearing high temperature has been often expressed in unusual circumstances. Heat and harmful to the bearing lubricant. Sometimes, bearing overheating can be attributed to the bearing lubricant and bearing 超过 long run at a temperature of 125 ℃, reduced bearing life, the cause of high-temperature bearings include: lack of lubrication or excessive lubricating oil containing impurities , heavy-duty, bearing damage, lack of space, with high temperature seal friction. Thus, continuous monitoring bearing temperature is necessary, whether it is measuring the bearing itself or other important part. If there is no change in operating conditions, any temperature changes may malfunction. Daily do roller bearing maintenance should pay attention to the details of the bearing temperature measurements can often help thermometer can accurately measure the bearing temperature, and according to degrees. NTN Bearing important, it is when it is damaged, it will cause equipment downtime, so these bearings should preferably be equipped with a temperature probe. Under normal circumstances, after bearing lubrication and lubricate natural temperature rise and last a day or two. Daily do roller bearing maintenance should pay attention to detail

If you have a good lubrication and the right barrier of debris and water bearing, said seal should not wear, but preferably in the open bearing housing, to visual inspection and periodic inspections bearing seals, bearing seals around checking conditions Make sure they are not enough to prevent liquids or corrosive liquids or gases from entering the bearing along the axis. Protection ring and labyrinth seals should be coated with grease to protect their maximum protection. Seal if worn should be replaced as soon as possible. Oil sealing function in addition to preventing the magazine to NTN Bearing, another function is to maintain lubrication of the bearing housing. If the seal leaks immediately check the seal has been worn or loose oil block. Leakage phenomenon may also be caused by loose connections or bearing housing add too much because the lubricating oil to form a mixed and leak detection, automatic lubrication system ensures the correct amount of lubricant, and examine whether color or black, if there is such a phenomenon, Generally speaking, lubricants containing magazine.
