Main aspects of regular maintenance inspection of IKO full complement cylindrical roller bearings

Regular inspections of IKO bearings are important for maintaining the best condition of a fully loaded cylindrical roller bearing and can also reveal problems. Matters and related knowledge about the use of bearings in use.
First of all, we want to emphasize that it is important to keep the IKO bearings lubricated and clean. Therefore, before we inspect the full complement cylindrical roller bearing, we should clean the surface of the bearing and then remove the parts around the bearing. It should be noted that the oil seal is a very fragile part, so extra care should be taken during inspection and disassembly. Do not apply excessive force to avoid damage to the parts. Then carefully check the bearing's oil seal and its surrounding parts. If it has been shown to be a bad symptom, be sure to replace it. A bad oil seal will cause damage to the bearing, causing the bearing cloud to be abnormal and causing the machine to stop.
Second, we also check the lubricant of IKO bearings. Lubrication is important, not for full complement cylindrical roller bearings, but for all bearings. However, please note that it is not advisable to add too much grease to the bearings.
Cleaning of IKO bearings: Gasoline and kerosene are commonly used as ordinary cleaning agents. When disassembling the lower bearing for inspection, first record the appearance of the full complement cylindrical roller bearing, confirm the residual amount of the lubricant, and start the washing of the bearing after sampling the lubricant for inspection. The cleaning is divided into coarse cleaning and fine cleaning, respectively placed in the container, and the metal mesh bottom is first placed so that the bearing does not directly contact the container dirt.
1. Rough cleaning, use brush to remove grease and adhesive, and after it is almost clean, transfer to fine washing. If the full complement cylindrical roller bearing is rotated with dirt, it will damage the rolling surface of the bearing and should be noted.
2, fine fine washing, is to fill the full complement of cylindrical roller bearings in the cleaning oil while carefully cleaning. In addition, the cleaning oil should always be kept clean.
IKO bearing inspection and judgment: In order to judge whether the removed bearing can be used, it should be checked after the full complement cylindrical roller bearing is cleaned.

The importance of grease in the maintenance of nsk tapered roller bearings

In order to determine whether the disassembled nsk tapered roller bearing can be used, it is necessary to check after the bearing is cleaned. Check the condition of the raceway surface, the rolling surface, the mating surface, the wear condition of the holding frame, the increase of the bearing clearance, and the damage and abnormality caused by irrelevant dimensional accuracy. For non-detached small ball bearings, use one hand to support the inner ring and rotate the outer ring to confirm whether it is fluent.
Overhaul of the bearing: Cleaning of the bearing: When disassembling the nsk tapered roller bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of the smoothing agent, and then wash the bearing after sampling the smoothing agent. As a cleaning agent, gasoline and kerosene are commonly used.
Outside the bearing industry, the type of grease used is the largest high-speed wire rod mill bearing, accounting for about 70% of the amount of grease used. Because the grease of this type is made of soft white, light and difficult to filter lithium-white thickener, using mineral oil as the base oil, it is very difficult to know the requirements of low-end bearings to reduce the vibration value. Another benefit is that there is no inferior pumping, whether it is mechanical fatliquoring or manual grease, it is simple and difficult. Moreover, the grease is inexpensive and can greatly reduce the cost of the nsk tapered roller bearing. However, due to the use of mineral essential oils, the greases are being combined with some physical and chemical targets other than rust and rust prevention. If the bearing life can only reach 200 hours, the linear guide is a common problem. The starting and running torques are no problem when tested at -20 °C. The grease utilization temperature is generally -20 to 120 ° C. When it is used at a high temperature of 150 ° C or higher, the fundamental oil evaporates too quickly, and the phenomenon of severe flow is greatly reduced, thereby greatly shortening the service life of the bearing.
1. The bearing oil bath is smooth
Smooth oil bath is a common smooth way in bearings, suitable for the smoothness of low and medium speed bearings. The nsk tapered roller bearing is partially immersed in the groove, the smooth oil is brought up by the rotating bearing part, and then flows back to the oil groove oil surface should be slightly lower than the center of the lowest rolling element.
2. The smooth drop of the bearing
Smooth drip is suitable for nsk tapered roller bearing parts that need to be quantitatively supplied with smooth oil. The amount of oil dripping is preferably every 3-8 seconds. Excessive oil quantity will cause the bearing temperature to increase.
3. The bearing's circulating oil is smooth
The oil is pumped to the bearing components by an oil pump, and then filtered and cooled by the smooth oil after the nsk tapered roller bearing. Because the circulating oil can take away a certain amount of heat and cool the bearing, this method is used for bearing parts with higher rotational speed.
4. The bearing spray is smooth
The use of boring shrinking air is mixed with smooth oil through a sprayer to create an oil mist. In the radial bearing, the air flow can effectively cool the bearing and prevent the intrusion of impurities. This method is suitable for the smoothness of high speed and low temperature bearing components.
5. The bearing's radiation is smooth
The low pressure oil is injected into the nsk tapered roller bearing through the nozzle by the oil pump, and the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at high speed, the rolling element and the cage also cause airflow around the surrounding air at a relatively high rotational speed. It is difficult to send the smooth oil to the bearing in a smooth manner. In this case, it is necessary to spray the smooth oil with low-pressure radiation. In the bearing, the position of the nozzle should be placed between the inner ring and the center of the cage.
