Ten oilless bearing maintenance tips to share with you.

What do cars, skateboards and industrial machinery have in common?They all rely on oilless bearings to maintain their smooth rotating motion.They must be properly maintained and handled for efficient operation and long service life.Proper curing will avoid many common problems that can lead to bearing failures and costly downtime.

1. Proper handling and storage

In order to avoid contaminants including moisture, dust or dirt entering oilless bush, they should be properly handled and stored.First, the oilless bearing should be placed horizontally in the original packaging in a clean, dry and room temperature environment.Avoid unnecessary handling of oilless bushing, for example, which may expose them to corrosion or contaminants if their inclusion is removed prematurely.oilless bearing are precision parts and should be handled with care.Therefore, dropped components should not be used, as this can lead to premature failure.

2. Use professional tools

Appropriate equipment should be used when handling Sliding Bearing.Non-special tools used during bearing installation and disassembly may cause unnecessary damage, denting and wear.For example, bearing pullers or induction heaters are designed specifically for Dry Bearing.

3. Check the bearing box and shaft

Before installing Plain Bushing, check the physical condition of the housing and shaft.Clean the surface with a soft cloth until you are familiar with the correct installation method.

4.Correct installation

When installing Plain Bearing, the correct method should be used, which depends on the type of bearing and the type of match.Centripetal ball bearing rings can be installed in a variety of fit modes, from sliding fit to compaction fit, depending on the type of load, speed and vibration level.Pressure applied to the wrong ring during installation may cause damage to the roller.Similarly, excessive looseness or tight coordination should be avoided, and the smoothness of the bearing seat should be too low or the round shaft or bearing seat is not correct.

5.Correct lubrication

One of the main reasons for bearing failure is lubrication failure.This includes using the wrong lubricant, as well as using too much or too little.Choose the right lubricant by considering environmental conditions, temperature, speed and load.Bearing experts will be able to make appropriate lubrication recommendations and control bearing lubrication within a few milligrams.Therefore, if you need low, normal or high grease filling, then you can rest assured that lubrication will not cause problems in the future.

6.Avoid temperature beyond bearing range

If steel Sliding Bearing are heated beyond their designed limits, the bearing material will be permanently deformed or softened, resulting in a reduction in carrying capacity and equipment failure.Selecting the right bearing for your temperature working range is the first step.Note discoloration of rings, rolling elements and cages during scheduled maintenance, as this may indicate overheating.This may be caused by excessive operating temperature and improper lubrication, so it needs to be brought to your attention quickly.

7.Corrosion prevention as far as possible

Corrosion is the natural enemy of oilless bearing.With the passage of time, corrosion will occur if oilless bushing are exposed to a wet environment.This can cause rust to enter the raceway and ultimately lead to premature failure of self lubricating bearing and equipment.Wearing gloves will ensure that sweat or other liquids will not enter the Sliding Bearing.When designing specifically for corrosive environments, selecting the right bearing is the key.For example, in Marine or chemical environments, choosing 316 stainless steel Plain Bushing with seals is usually a good choice.

8.Choose alternatives carefully

If the bearing does reach its service life, please replace the bearing with a bearing of the same or higher quality as the original bearing.In the long run, low-quality alternatives are likely to fail and may result in more expensive equipment failure.

9.Real-time monitoring

self lubricating bearing rarely fail without any warning signal.Too much noise, vibration or a rise in temperature can be signs of deeper problems.If there is any abnormal operation of the bearing, it should be monitored more closely.


Finally, if in doubt, seek expert help.Bearing experts will advise you on the best maintenance methods for a particular application and will be able to help you diagnose any bearing problem.It is simple to send the problem bearing to an expert who will inspect and lubricate the bearing as needed.
