IKO universal joint bearing are high-quality components that are designed to allow shafts to transmit torque even when they are misaligned. These bearings are typically used in a wide range of applications, including industrial machinery, automotive drivetrains, and construction equipment.
Made from durable materials and designed to resist the impacts of high loads, vibration, and shock, IKO universal joint bearings are built to provide reliable, long-lasting performance even in the harshest operating environments. With proper installation and maintenance, these bearings can help to ensure the smooth and efficient operation of machinery and equipment across a broad range of industries.
If IKO bearing is well lubricated and properly blocked from 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 near the universal joint 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.Common maintenance methods for abnormal operation of IKO combined bearing
Common damage and failure of IKO universal joint bearing and corresponding countermeasures
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 universal joint bearing include insufficient or excessive lubrication, magazine contained in lubricant, excessive load, IKO bearing damage, insufficient clearance, high temperature friction caused by oil seal, etc
Burn: serious temperature rise of the bearing, resulting in burn and failure to rotate.Common maintenance methods for abnormal operation of IKO combined bearing
Cause: the clearance is too small; Insufficient lubrication or improper lubricant; Roller inclination; Excessive load; In the case of temperature rise, the hardness is low.Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Measures: check the type of lubricant and ensure the filling amount; Set appropriate clearance; Check the service conditions; Prevent the center line of universal joint bearing from tilting; Check the design around the bearing;Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Stripping: the surface of the raceway movable rolling element is stripped, and the stripping is concave and convex.Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Cause: excessive load and poor use; Poor installation; Poor accuracy of shaft or universal joint bearing housing; Not enough games; Dust entry; rust; Improper lubrication; When the temperature rises, the hardness decreases.Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Measures: re select the bearing; Reconsider the clearance and check the machining accuracy of shaft and bearing housing; Re study the service conditions; Check the installation method; Check the lubricant and lubrication method.Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Abrasion: there are two types of abrasion: one is that red wear powder particles are generated on the mating surface, and the other is that Brinell indentation is generated on the rolling element
Cause: insufficient interference; The swing angle of IKO bearing is insufficient; Insufficient lubrication; Uncertain load, stability, vibration
Measures: check the interference and lubricant status; The inner and outer rings shall be packed separately during transportation; Reselect lubricant; IKO bearing re selection
Cage damage: the rivet is loose or broken, and the cage is broken.
Cause: excessive torque load; High speed rotation or frequent speed change; Poor lubrication; Foreign matter stuck; Large vibration; Poor installation.Common maintenance methods for abnormal operation of IKO combined bearing
Measures: check the lubrication conditions; Re study the selection of cage; Check the service conditions; Improve installation methods.Common maintenance methods for abnormal operation of IKO combined bearing
Speed and temperature rise
With the development of science and technology, the spindle speed of machine tool is higher and higher, and the speed range is larger and larger. Therefore, the requirements for the high-speed operation stability of IKO bearing are higher and higher.
The temperature rise of machine tool spindle bearing is an important factor to limit the bearing speed. Generally, the correct selection of bearing type, tolerance grade, configuration mode, clearance (preload), lubricant and lubrication mode can improve the high-speed performance of plastic bearings to a certain extent.
Service life and bearing capacity
For general machine tools, the service life of the spindle assembly mainly refers to the service life of maintaining the spindle accuracy. Therefore, the accuracy maintenance performance of the bearing is required to meet the requirements of the service life of the spindle assembly.
For heavy machine tools or power cutting machine tools, the bearing capacity of IKO bearing should be considered first.Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Stiffness and vibration resistance
In order to ensure the machining quality of the machine tool, the spindle system must be rigid enough, otherwise it will produce large re mapping error and even flutter. Vibration resistance refers to the ability to resist forced vibration and self-excited vibration.
The vibration resistance of the spindle assembly depends on the stiffness and damping of the spindle and IKO bearings. The use of preloaded plastic bearings can effectively improve the stiffness of the spindle system.Common damage and failure of IKO universal joint bearing and corresponding countermeasures
Noise
In high-speed grinder, the noise of grinding head bearing is the main component of the whole machine noise, so low-noise plastic bearing should be selected.Common maintenance methods for abnormal operation of IKO combined bearingCommon damage and failure of IKO universal joint bearing and corresponding countermeasures
