INA roller bearings are maintenance inspection standards

In order to fully utilize INA bearings and 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 economy.

Key factors affecting the life of a roller bearing For many rotating machinery products, their service life depends on the life of the bearing components at critical parts of the product. "Maintenance-free" bearings are not one-way bearings that will never be damaged or failed but will not be damaged within a certain period of time. Here the designers calculate the service life of the bearing. The bearing life of the INA bearing is greater than or equal to the overhaul period of the mechanical product. The bearing can be “maintenance free”. When the mechanical product is overhauled, the new bearing can be replaced without using the used bearing. Carry out maintenance.

1, cleaning

When the INA bearing is removed for inspection, the appearance record is first recorded by photography. Also, verify the amount of lubricant remaining and sample the lubricant before cleaning the bearings.

a. The cleaning of the bearing is carried out by rough washing and fine washing, and a metal mesh frame can be placed on the bottom of the used container.

b. When rough washing, remove the grease or adhesive with a brush or the like in the oil. At this time, if the bearing is rotated in the oil, be careful that the rolling surface will be damaged by foreign matter or the like.

c. When washing finely, slowly rotate the bearing in the oil and carry out it carefully.

The cleaning agent generally used is a neutral non-aqueous diesel oil or kerosene, and a warm alkali liquid or the like is sometimes used as needed. Regardless of which cleaning agent is used, it is often filtered and kept clean.

Immediately after cleaning, apply anti-rust oil or anti-rust grease to the roller bearings.

2, inspection and judgment

In order to judge whether the removed bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and seal.

Regarding the inspection result, it can be judged by a person who is using a conventional bearing or a proficient bearing.

Lubrication and maintenance knowledge of high temperature and high speed INA slewing bearings

Bearings in the process of use due to their own quality and external conditions, their load capacity, rotation accuracy and wear resistance will change. When the performance index of the slewing bearing is lower than the use requirements and can not work properly, INA bearing has occurred If the fault even fails, the machine and equipment will stop and there will be various abnormal phenomena such as loss of function in case of failure of the bearing, etc. Therefore, it is necessary to find out the cause in a short period of time and take corresponding measures.

The high-temperature thickener thickens the synthetic oil and adds multi-effect additives, which is a high-quality grease that maintains normal working conditions in a high temperature environment for a long time.

A High temperature tolerance and high-speed shear resistance make it easy to handle in high temperature and high speed environments.

B Excellent high and low temperature resistance, lubricity, good colloidal stability and mechanical stability.

C The temperature range is -40~230°C and the short time is 250°C.

D is suitable for mechanical use where there is a requirement to reduce noise or the environment is extremely harsh, and it is also suitable for lubrication at high temperatures.

E Waterproof, resistant to water rinsing and maintaining hardness over a wide temperature range. Excellent anti-oxidation performance, good anti-wear performance, resulting in extremely long service life and 5-10 times the service life of lithium base grease.

F is suitable for lubrication of precision bearings, motor bearings and miniature bearings in high and low temperature environments.

G Suitable for lubrication of various high speed bearings, high speed long life gyro motors, high speed grinding machines and other high speed instruments and mechanical INA bearings.

H The structure is smooth, the fiber is fine, and it has high cleanliness. It can suppress the abnormal sound of the slewing bearing during operation and meet the long-term operation requirements of high-speed bearings with DN value above 500,000.
