Precautions for the use of the 6009 2rs bearing and how to maintain the bearing to extend its service life

How to judge the 6009 2rs bearing failure

A sound meter is used to check the size and sound quality of the rolling sound of the 6009 2rs bearing in operation. Even if the bearing is slightly damaged such as peeling, abnormal and irregular sounds will be emitted, which can be distinguished by the sound meter. It is a very common method to use hearing to recognize irregular movements.

1.The 6009 2rs bearing will make a low whining sound if it is in a good continuous rotation state. If there is a sharp hiss, squeak and other irregular sounds, it often indicates that the bearing is in a bad continuous rotation condition. The sharp squeaking noise may be caused by improper lubrication. Inappropriate bearing clearance can also cause metallic noise.

2.The dent of the concave track on the outer track of The 6009 2rs bearing will cause vibration and cause a smooth and crisp sound.

3.If it is caused by knocking scars during installation, noise will also be generated, and this noise will vary with the speed of the 6009 2rs bearing.

4.If there is intermittent noise, it means that the rolling parts may be damaged. This sound occurs when the damaged surface is rolled over, if there are contaminants in the 6009 2rs bearing, it will often cause a hissing sound. Severe co-carrying damage will produce irregular and loud noise.Wuxi Spark Bearing Co.,Ltd is the complete, one-stop bearings supplier & manufacturer.

5.The 6009 2rs bearing damage can be judged by hearing, but usually the 6009 2rs bearing must be replaced immediately when it has arrived. Therefore, a better method can use electronic condition monitoring equipment to detect. Compared with the old method, using a wooden stick or screwdriver against the bearing box and the other end against the ear, this method can ensure a safer and more accurate estimation of the 6009 2rs bearing status.

Common problems and countermeasures in the use of the 6009 2rs bearing

1.Abnormal load: select the appropriate assembly clearance and pre-tightening force.

2.Poor assembly: improve the machining accuracy of the shaft and improve the installation method.

3.Insufficient lubricant: supplement or use suitable lubricant.

Rotational vibration of the shaft is large

1.Spalling: fatigue spalling, replace the bearing.

2.Poor assembly: improve the machining accuracy of the shaft and improve the installation method.

3.Foreign matter intrusion: clean relevant parts and use clean grease.

Lubricant leakage and discoloration

1.Too much lubricant: reduce lubricant.

2.Foreign body intrusion: cleaning related parts

Precautions for the use of the 6009 2rs bearing

1.Keep the 6009 2rs bearing and its surrounding environment clean.

Even if tiny dust invisible to the naked eye enters the 6009 2rs bearing, it will increase bearing wear, vibration and noise. Bearings and their surrounding accessories should be kept clean, especially dust and dirt. Tools and the environment must also be kept clean.You can send an email to sales@spark-bearing.com at any time.

2.Precautions when using and installing the 6009 2rs bearing

It is not allowed to press hard, directly hit the bearing with a hammer, and not to transmit pressure through the rolling elements.

3.Use suitable installation tools

Try to use special tools and try to avoid using things like cloth and short fibers.

4.Prevent bearing corrosion

When holding the bearing directly by hand, wash away the sweat from your hands and apply high-quality mineral oil before operating. Pay special attention to rust prevention during the rainy season and summer.

What kinds of lubrication methods are there?

1.Manual lubrication

This is the most primitive method. If the bearing is insufficiently lubricated, use an oiler to supply oil. It is usually only used for light load, low speed or intermittent exercise. In order to achieve the best operation, a dust cover or ball valve is installed on the fuel port. In addition, felt, cotton, wool, etc. are used as filter devices.

2.Drop a little oil

Usually used for light-duty and medium-duty bearings with a peripheral speed of less than 4-5m/s. An almost constant amount of lubricant is injected from the container through holes, needles, valves, etc. supply. When using an oil cup, the amount of oil dropped will vary greatly depending on the viscosity of the lubricating oil, the clearance of the bearing, and the location of the lubrication hole.

3.Oil ring shape

By rotating the ring suspended on the shaft, the lubricating oil in the oil sump is brought to the bearing (only for horizontal shaft lubrication method), and the shaft diameter is increased to a medium speed exceeding 50 mm. Suitable for. If the bearing aspect ratio is less than 2, only one oil ring can be used; otherwise, two oil rings are required.

4.The shape of the oil

According to the capillary action and siphon action of the oil rope, the lubricating oil in the oil cup is introduced into the bearing. In addition to oil, it is mainly used for light and medium-sized bearings with a peripheral speed of less than 4-5 meters per second. The rope can act as a filter during the entire process.

5.Oil pad packaging

Use the capillary action of the oil pad to apply the lubricant in the oil pool to the diameter surface of the shaft. This method can keep the friction surface clean, but it can also block the air holes and prevent insufficient oil supply.

6.Oil tank shape

This lubrication method is used to immerse part of the bearing in the lubricating oil, and is usually used for vertical thrust bearings instead of horizontal radial bearings. Please

7.Splash lubrication

Provide bearings for the bearings according to the slippage of the rotating parts in the bearing box. Suitable for high-speed bearings.

8.Highly spray lubrication

The method of spraying lubricant on the friction surface is suitable for high-speed bearings.

9.Pressure oil lubrication

The oil is supplied to the bearing by the pressure of the lubricating pump, and the lubricating oil flowing from the bearing is collected in the oil pool and recovered.

10.Circulating oil lubrication

Use an oil pump to deliver the filtered oil to the bearing parts. After the bearing is used, filter and cool the lubricating oil.
