In order for IKO bearings to be fully utilized and to maintain their proper performance for a long time, regular maintenance (regular inspection) must be performed. Through proper periodic inspections, early detection of failures and prevention of accidents are important to improve productivity and cost.
(1) Cleaning
When disassembling the IKO bearing for inspection, first record the appearance of the bearing, confirm the residual amount of the bearing lubricant, and after cleaning the IKO bearing after sampling and checking the lubricant, generally use kerosene or gasoline, and sometimes use a warm alkali solution as needed. But no matter which kind of clearing agent is used, it must be filtered and kept clean.
l IKO bearing cleaning is divided into rough washing and fine washing. In the container, the metal mesh bottom is placed first, so that the IKO bearing does not directly touch the dirt in the container.
l When rough washing, remove grease or adhesive with a brush or the like in the oil. At this time, if the IKO bearing is rotated in the oil, be aware that the IKO bearing rolling surface may be damaged by foreign matter or the like.
l During the fine washing, the IKO bearing is rotated in the oil and the bearing is carefully rotated while rotating.
l Immediately after cleaning, apply anti-rust oil or anti-rust grease to IKO bearings.
(2) Inspection and judgment
In order to judge whether the removed IKO bearing can be used, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance and mating surface, raceway surface, rolling surface, cage and seal ring.
Regarding the inspection results, it can be judged by experienced persons or those who are proficient in IKO bearings. The criteria for judgment vary depending on mechanical properties and importance, inspection period, and the like. IKO bearings must not be reused if they are damaged and must be replaced.
l IKO bearing parts are broken and defective.
l Peeling of the raceway surface and the rolling surface.
l Others such as IKO bearing damage examples are severely damaged.
