Regular inspection of the bearing in the best condition for maintaining the bearing is a very important work, also can embody discovered the problem. Bearing in use should be noted that t he matters related knowledge.
First of all, we want to stress, the NTN Bearing lubrication and clean is very important. NTN bearigs checked, you should clean NTN Bearing surface, then remove the bearing surrounding parts. It should be noted that the oil seal is very fragile parts, so need to be extra careful inspection and disassembly, do not use excessive force, in order to avoid damage to the parts. Then carefully check NTN Bearing oil seal and the surrounding parts have shown adverse symptoms, be sure to replace the lost, poor seal can cause damage to the bearing, NTN Bearing cloud unusual cause equipment downtime.
Secondly, we need to check the the NTN bearings of lubricant. Lubrication is very important, not just for NTN bearings, but also for all the bearings. Note, however, the NTN bearings should not add too much grease.china bearing
About NTN Be aring lubricant inspection methods:
The stained little bit of lubricant between two fingers friction, if the contamnt is feeling out; coated with a thin layer of lubricant in the back of the hand, and then seal ray examtion.
Then, is to replace the NTN bearing lubricant.
NTN bearings using oil lubrication, if you can, then in addition to the old oil spilled, it should be re-poured fresh oil and let the machine a few minutes at low speed rotation. As much as possible so that the oil collected the remnant contamnts, and then spilled addition to these oil. Note: Oil is best to use filtered. NTN Bearing replacement grease use grease lubrication, Joe divider should be avoided with cotton material then angle to the bearing of any parts. Because these residual fibers may be wedged in between the rolling elements and damage, especially small bearing should pay more attention to this problem.
Flly, you need to pay attention to cover exposed NTN Bearing.
Do no t let the bearings, check NTN Bearing exposure to pollutants or moisture environment. If the work is interrupted greaseproof paper plastic sheet or similar material to cover once the machine.
In order to judge removed NTN Bearing Can I re-use, to focus on to check the dimensional accuracy of rotational accuracy, internal clearance, and the mating surface raceway, cage and seals.
About inspection results can be used to bearing or proficient bearing judge.high speed bearing
Different standard of judgment based on the mechanical properties and the degree of importance and inspection cycle. If injury, NTN bearings shall not be re-used and must be replaced.
a) the bearing components in fracture and defects.
b) raceway material rolling surface stripping.
Good appearance record the NTN bearings removed for inspection, using photography and other methods. In addition, to confirm that the rem aining amount of lubricant and lubricant sampling, then cleaning bearings.
