Lubrication Quality Effectively Prolongs The Service Life Of Koyo Tapered Roller Bearings

Koyo Tapered Roller Bearings

Grease is indispensable in the work of tapered roller bearings. The Koyo Tapered Roller Bearings maintenance of any Koyo bearing is inseparable from grease. Someone asked, is the more grease the better? Of course, the answer is No. here are the precautions for using grease in bearings.

In the maintenance of tapered roller bearings, too much grease actually has many hazards. Because the grease has good adhesion, wear Koyo Tapered Roller Bearings resistance, temperature resistance, rust resistance and lubricity, it can improve high-temperature oxidation resistance,

delay aging, dissolve carbon deposition, prevent the agglomeration of metal wear debris and oil, and improve the wear Koyo Tapered Roller Bearings resistance, pressure resistance and corrosion resistance of machinery.

1. Bearing installation

Whether the tapered roller bearing is installed correctly affects the accuracy, service life and performance. Therefore, the design and assembly department should fully study the installation of Koyo bearing. It is hoped that the installation will be carried out according to the operating standards. Items of operating standards are usually as follows:

(1) Clean the bearing and its related parts

(2) Check the size and finish machining of related parts

(3) Installation

(4) Inspection after bearing installation

(5) Supply lubricant

2. Basic condition monitoring of bearing

During use, the basic external Koyo Tapered Roller Bearings conditions of tapered roller bearing operation should be monitored frequently, such as temperature, vibration and noise measurement.

These regular inspections will identify potential problems as soon as possible, prevent unexpected machine stoppage, realize the Koyo Tapered Roller Bearings production plan and improve the productivity and efficiency of the plant.

3. Re lubrication of bearings

In the process of operation, tapered roller bearing requires correct re lubrication to perfect its performance. The lubrication methods of Koyo bearings are divided into grease lubrication and oil lubrication. In order to make the bearing function well,

first of all, choose the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease  Koyo Tapered Roller Bearings lubrication has the advantage of simplifying the structure around the bearing.

Note:

4. Unloading of bearing

Tapered roller bearings should be replaced when they reach their final service life.

Although tapered roller bearings can no longer be used, correctly Koyo Tapered Roller Bearings removing the original Koyo bearings and replacing new bearings in time can play a good role in prolonging the service life of new bearings.

Precautions for daily maintenance of Timken plain bearing

How To Do Routine Maintenance For Iko High Temperature Bearing

After the installation of Timken bearing, in order to check whether the installation is correct, operation inspection shall be carried out. Koyo Tapered Roller Bearings Small machinery can be rotated by hand to confirm whether it rotates smoothly.

The inspection items include poor operation caused by foreign matters, scars and indentation, unstable torque caused by poor installation and poor processing of mounting base, excessive torque caused by too small clearance, installation error and sealing friction, etc.

If there is no abnormality, the power operation can be started. Large machinery cannot rotate manually, so the power shall be cut off immediately after no-load start, and the machinery idles. Check whether there is vibration, noise, contact of rotating parts, etc. after confirming that there is no abnormality,

enter the power operation. Power operation, starting from no-load and low speed, slowly increase to the Koyo Tapered Roller Bearings rated operation under the specified conditions. During the test run, the inspection items are whether there is abnormal sound, the temperature change of plane bearing,

the leakage or discoloration of lubricant, etc. If any abnormality is found, stop the operation immediately, check the machinery, and remove the bearing for inspection if necessary.

The temperature can generally be inferred from the external temperature of the bearing seat. However, it is more accurate to directly measure the temperature of Timken bearing outer ring with oil hole. The bearing temperature rises gradually from the beginning of operation, and the temperature is usually stable after 1 ~ 2 hours.

If the bearing is not installed properly, the temperature will rise sharply, resulting in abnormal high temperature. The reasons are too much lubricant, too small bearing clearance, poor installation, excessive friction of sealing device, etc. In the case of high-speed rotation, the wrong selection of structure and lubrication mode is also the reason.

1. Keep the bearing and its surroundings clean.

Even small dust that cannot be seen by the eyes will have a bad impact on Timken bearings. Therefore, keep the surrounding clean so that the dust will not invade the plane bearing.

2. Use the bearing carefully and give Timken bearing strong impact during use, which will produce scars and indentation, which will become the cause of the accident. In serious cases, it will crack and fracture, so we must pay attention to it.

3. Use proper operation tools

Avoid replacing with existing tools, and appropriate tools must be used.

4. Pay attention to the corrosion of plane bearing

When operating the bearing, the sweat on the hand will become the cause of rust. Pay attention to operate with clean hands and try to wear gloves.

Understanding the use method of Timken bearing will get twice the result with half the effort, which is very important.

When the mechanical parts near the bearing have been lubricated with oil or need to be dissipated by lubricating oil, the bearing shall be lubricated with oil. When the 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 mixing loss and 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.

Where the rotating speed of plane bearing is very high and good cooling is required, a large amount of lubricating oil can be sprayed directly onto all contact surfaces.
