Under What Circumstances Do Timken Bearings Take Supplementary Lubrication To Avoid Heating Failure

Under What Circumstances

If the lubrication interval is shorter than six months, the method of Under What lubricating grease supplement is adopted. This method is relatively simple and will not interrupt the operation of the equipment. Compared with continuous lubrication, it can maintain firm temperature and lower level.

When the lubrication interval is better than six months, it is generally recommended to renew the grease. Grease renewal is usually part of regular maintenance of Timken bearings, such as railway bearings.

If supplementary lubrication is required more frequently for Under What different reasons, such as pollution, or other supplementary lubrication methods are inconvenient because it is not easy to access the position of Timken inlet bearing.

The method of continuous lubrication can be considered. Under What Continuous grease is not suitable for high speed applications because excessive agitation of the grease may cause an increase in operating temperature and damage the structure of the grease thickener.

Bearing is a fixed part of Under What machinery and the main body of machinery. Its function is basically to maintain the central position of the shaft and control the movement. Timken bearing plays an important role in any machine. Without the bearing, the machine cannot run.

Under What Circumstances Do Timken Bearings Take Supplementary Lubrication To Avoid Heating Failure

Many users have reported that when using imported bearings, Timken bearing heating fault is Under What common, which will also affect the service life and performance of Timken imported bearings. So, how did this fault form? Here are some knowledge summarized for you.

1. The oil level is too low and the lubricant is lost from the oil seal;

2. The grease in Timken bearing box is completely filled or the oil level is too high. This will lead to excessive mixing of lubrication, Under What high temperature or oil leakage;

3. The contact (friction) oil seal is too dry or the spring is too tight;

4. The hole in Timken bearing box is not round; Distortion and deformation of bearing housing; Under What The bearing surface is not flat; The inner diameter of the box hole is too small;

5. The contact (friction) oil seal is too dry or the spring is too tight.

How to choose the lubrication mode of INA Bearing

Disassembly Skills And Maintenance Methods Of Fag Bearings In Germany

There are two ways to choose ina bearing lubrication: oil lubrication and grease lubrication. These two lubrication methods have their Under What own advantages and disadvantages.

grease

Generally, rolling ina bearings are lubricated with grease. Its advantages mainly include:

The design is very simple

Grease can play a great sealing role

Low maintenance cost and long service life

Under normal working and environmental conditions, grease may achieve “lifelong lubrication”. If under high load conditions (speed, temperature, load), the grease must be changed regularly.

In order to change the grease, it is necessary to set up pipes to supply and discharge the grease and collect the used grease collector. For the occasion of changing lubricating grease in a short period, necessary pumps and valves for injecting lubricating grease shall be set.

Oil lubrication

When the mechanical parts near ina bearing have been lubricated with oil or need to be dissipated by lubricating oil, INA Bearing shall be lubricated with oil. When ina bearing is under heavy load or high speed, or there is external heat transfer, there may be heat dissipation requirements.

The micro lubrication method, such as oil drop lubrication, oil mist lubrication or oil-gas lubrication, can ensure that the oil stirring loss and ina bearing friction are very small.

When air is used as a carrier, it can directly supply oil and make the air flow contribute to sealing.

Ina bearing can spray a large amount of lubricating oil directly to all contact surfaces where the rotating speed is very high and good cooling is required.
