The important role of SKF non-standard bearing lubrication in the elimination of the guide

In general, non-standard bearings heat up after they start running, and after a period of time, they are at a lower temperature (usually 10 to 40 degrees higher than room temperature). The normal time is different depending on the size, form, rotation speed, lubrication method of the SKF bearing, and the exothermic conditions around the non-standard bearing. It takes about 20 minutes to several hours.

When the temperature of the non-standard bearing does not reach the normal state and the abnormal temperature rises, the following reasons may be considered. In addition, the machine should be stopped as soon as possible and necessary countermeasures should be taken. Temperature is essential for maintaining the proper life of non-standard bearings and preventing deterioration of lubricating oil. It is recommended to use as much as possible under non-high temperature conditions (generally below 100 degrees). The main cause of abnormal temperature rise is too much or too little. Poor installation of SKF bearings. The internal clearance of non-standard bearings is too small, or the load is too large. The friction of the seal is too large. The lubricant does not match. The creep of the mating surface.

1. Firstly, the parts of the SKF bearing are lubricated to reduce the friction and wear of the bearing;

2. The rolling contact surface of the bearing often forms an appropriate oil film to prolong the fatigue life of the non-standard bearing;

3. The heat generated by friction or other reasons inside the bearing is removed by lubrication;

4. Through lubrication, it can achieve anti-rust and dust-proof effects on non-standard bearings.

Therefore, we must correctly understand the importance of lubrication for SKF bearings, improve bearing performance and reduce consumption.

Lubrication quality effectively extends the service life of KOYO tapered roller bearings

Grease is a tapered roller bearing that is indispensable in the work. Any KOYO bearing can not be separated from the grease. Some people ask, is the more grease the better? The answer is of course no, below As far as the bearing is concerned, the grease should be used.

In the case of tapered roller bearings, excessive grease actually has many hazards. Because grease has good adhesion, wear resistance, temperature resistance, rust resistance and lubricity, it can improve high temperature oxidation resistance, delay aging, dissolve carbon deposits, and prevent metal chipping and oil staining. Improve the wear resistance, pressure resistance and corrosion resistance of the machine.

1, the installation of the bearing

Whether the tapered roller bearing is installed correctly affects accuracy, life and performance. Therefore, the design and assembly department should fully study the installation of KOYO bearings. I hope to install according to the operating standards. The items of the job standard are usually as follows:

(1) Cleaning bearings and bearing related parts

(2) Check the size and finishing of the connected parts

(3) Installation

(4) Inspection after mounting the bearing

(5) Supply lubricant

2. Basic condition monitoring of bearings

During use, the basic external conditions of the operation of tapered roller bearings are often monitored, such as temperature, vibration and noise measurements. These regular inspections will identify potential problems early and will prevent unexpected machine stops, enabling production plans, increased plant productivity and efficiency.

3. Relubricate the bearing

During operation, tapered roller bearings require proper relubrication to perfect its performance. KOYO bearing lubrication method is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first, choose a lubrication method that suits the conditions of use and the purpose of use. Lubricity of oil lubrication predominates if only lubrication is considered. However, grease lubrication has the advantage of simplifying the structure around the bearing.

Note:

4, the unloading of the bearing

When the tapered roller bearing will reach its end of life, it should be replaced.

Although the tapered roller bearing can no longer be used, correctly removing the original KOYO bearing and replacing the new bearing in time can promote the service life of the new bearing.
