Rolling mill bearing

How to maintain and maintain Rolling mill bearing on a daily basis

As the core component of rolling mill equipment, the stability of its performance and the length of its service life are directly related to the operating efficiency and production benefits of rolling mill equipment, so it is very important to perform daily maintenance and maintenance on Rolling Mill Bearing.

1. Cleaning and inspection
Regular cleaning: During operation, Rolling Mill Bearing will accumulate dust, oil and other impurities, which will affect the lubrication effect and heat dissipation performance of the bearing. The bearing needs to be disassembled and cleaned with a cleaning agent regularly. When cleaning, pay attention to protecting the bearing from direct contact with the dirt in the container to avoid damaging the rolling surface of the bearing.
Appearance inspection: During the cleaning process, carefully check the appearance of the bearing, including whether there are cracks, peeling, rust and other phenomena on the bearing surface, as well as the wear of components such as rolling elements and cages. For abnormally worn or damaged components, they should be replaced in time.

2. Lubrication management
Lubrication method selection: The lubrication methods of Rolling Mill Bearing mainly include oil bath lubrication, drip lubrication, circulating oil lubrication, spray lubrication and jet lubrication. The specific lubrication method should be comprehensively considered based on the bearing's speed, load, working environment and other factors.
Lubricant selection: The selection of lubricants has a great impact on the lubrication effect and service life of the bearing. Lubricants with stable quality and excellent performance should be selected, and the type and brand of lubricants should be determined according to the bearing's speed, load, working environment and other conditions.
Regularly replace lubricants: Lubricants will gradually age, deteriorate and lose their lubricating effect during use, so lubricants need to be replaced regularly to ensure the lubrication effect of the bearing. The specific replacement cycle should be determined based on the use of the bearing and the performance of the lubricant.

3. Installation and disassembly
Correct installation: The installation of Rolling Mill Bearing should be carried out in the correct way, avoiding improper operations such as strong stamping and hammering to avoid damage or deformation of the bearing. Special tools and equipment should be used for installation, and an appropriate amount of lubricant should be applied to reduce friction and wear during installation.
Standardized disassembly: When disassembling Rolling Mill Bearing, attention should also be paid to standardized operations to avoid damage to bearings or related components. Before disassembly, marking and records should be made so that accurate resetting can be achieved during subsequent installation.

IV. Regular inspection and maintenance
Operation status inspection: Regularly check the operation status of the Rolling Mill Bearing, including indicators such as rotation sound, vibration, and temperature. For abnormal phenomena, find the cause and deal with it in time.
Lubrication system inspection: Check whether the oil circuit of the lubrication system is unobstructed and whether the oil pump, oil nozzle and other components are working properly. For faults or problems in the lubrication system, repair or replace related parts in time.
Maintenance records: The maintenance work of the Rolling Mill Bearing should be recorded, including details of cleaning, inspection, replacement of lubricants, installation and disassembly, etc. These records can be used as a reference for subsequent maintenance work.
