Common damage causes affecting the service life of IKO needle roller bearing

IKO is a renowned brand in the needle roller bearing market. Their products are widely recognized for their high-quality, durability and precision. The IKO needle roller bearing is a critical component in many industrial applications, providing reliable support for rotating components and reducing friction. With their advanced technology and engineering expertise, IKO continues to innovate and expand their product line to meet the evolving needs of their customers.

Whether the needle roller bearing is installed correctly affects the accuracy, service life and performance. Therefore, the design and assembly department should fully study the installation of IKO bearing. The installation shall be carried out according to the desired standard. Items of operating standards are usually as follows:Common damage causes affecting the service life of IKO needle roller bearing

Common damage causes affecting the service life of IKO needle roller bearing

Clean the bearing and its related parts
Check the size and finish machining of related parts Installation
Supply lubricant
After installation and use, the bearing shall be tracked and monitored
During use, the basic external conditions of needle 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 production plan and improve the productivity and efficiency of the plant.Common damage causes affecting the service life of IKO needle roller bearing
3. Complete the re lubrication correctly and reasonably
In the process of operation, IKO bearing requires correct re lubrication to perfect its performance. The methods of bearing lubrication are divided into grease lubrication and oil lubrication.
In order to give full play to the function of the bearing, it is necessary to select suitable service conditions and use correct lubrication methods.Common damage causes affecting the service life of IKO needle roller bearing
If only lubrication is considered, the lubricity of oil lubrication is dominant, but grease lubrication has the advantage of simplifying the structure around the bearing. Therefore, the selection should be based on the needs of the actual use environment.Common damage causes affecting the service life of IKO needle roller bearing
4. Be careful when unloading the bearing
When the needle roller bearing will reach its final service life, it should be replaced. Although the needle roller bearing can no longer be used, correctly removing the original bearing and replacing the new bearing in time can play a good role in prolonging the service life of the new bearing.Common damage causes affecting the service life of IKO needle roller bearing
(1) Proper removal methods and the use of tools will help prevent damage to other machine components,
(2) Improperly removed technology can be hazardous to the operator.Common damage causes affecting the service life of IKO needle roller bearing
If the needle roller bearing is well lubricated and correctly blocks sundries and moisture, it means that the oil seal should not be worn However, when opening the bearing housing, check the bearing and regularly check the oil seal Check the condition of oil seals close to IKO bearing to ensure that they are sufficient to prevent hot liquid or corrosive liquid or gas from penetrating into the bearing along the axis. If the oil seal is worn, replace it as soon as possible

High temperature often indicates that the bearing is in abnormal condition High temperatures are also harmful to lubricants in bearings Sometimes bearing overheating can be attributed to the lubricant of the bearing If the bearing operates for a long time at a temperature of more than 125 ℃, the service life of the bearing will be reduced
The causes of high-temperature bearing include insufficient or excessive lubrication, magazine contained in lubricant, excessive load, bearing damage, insufficient clearance, high-temperature friction caused by oil seal, etc
The bearing IKO body and the inner and outer race raceways are subjected to periodic fluctuating loads, resulting in periodic contact stress. When the number of stress cycles reaches a certain value, fatigue spalling occurs on the working surface of IKO body or inner and outer race raceways.
If the load of the bearing is too large, it will aggravate this fatigue. In addition, improper bearing installation and shaft bending will also produce raceway spalling. The fatigue spalling of bearing raceway will reduce the operation accuracy of shaft and cause vibration and noise of mechanism.Common damage causes affecting the service life of IKO needle roller bearing
There is a return fire color on the raceway and IKO body of the burned bearing.
The causes of burns are generally insufficient lubrication, unqualified or deteriorated lubricating oil quality, and too tight bearing assembly.Common damage causes affecting the service life of IKO needle roller bearing
Uneven pits appear on the contact surface between the raceway and the roller of the bearing, indicating that the needle roller bearing produces plastic deformation.
The reason is that under the action of large static load or impact load, the local stress on the working surface of IKO bearing exceeds the yield limit of the material, which usually occurs on the bearing rotating at low speed.Common damage causes affecting the service life of IKO needle roller bearing
