Key Points for Maintenance of IKO Bearing

Key Points for Maintenance of IKO Bearing

  • The inspection of IKO bearing during operation is very important and can not be ignored. It mainly checks the rolling sound, vibration, temperature, lubrication state and so on. Let’s first briefly introduce the rolling sound of the bearing. 
  • The size and sound quality of the rolling sound should be checked by the sound detector. The problem will be accurately judged by advanced tools. Even if the bearing has slight peeling and other damage, it will emit abnormal sound and irregular sound, which can be distinguished by the sound detector.Key Points for Maintenance of IKO Bearing
  • Then check the vibration of IKO bearing to see if the damage of the bearing is very sensitive. Whether peeling, indentation, corrosion, crack, wear, etc. will be reflected in the bearing vibration measurement. Therefore, the vibration can be measured by using a special automobile bearing vibration measuring instrument (frequency analyzer, etc.), and the specific abnormal situation can not be inferred by frequency division. 
  • However, the values measured by each machine are different due to the service conditions of the bearing or the installation position of the sensor, so it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.Key Points for Maintenance of IKO Bearing
  • IKO bearing parts are affected by abnormal high temperature in use and cannot be cooled in time, so the phenomenon of high temperature tempering or secondary quenching on the surface structure of the parts is called burn.Key Points for Maintenance of IKO Bearing
  • The main causes of burns are poor lubrication, excessive neck load, improper clearance selection, improper bearing configuration, poor contact on raceway surface, excessive stress and so on. If;Key Points for Maintenance of IKO Bearing
  • 1) In the axial traveling bearing, if the external matching is too tight, it cannot move in the shell hole;
  • 2) When the operating temperature of the bearing increases during operation, the thermal expansion of the shaft causes great axial force, and the bearing cannot move axially;Key Points for Maintenance of IKO Bearing
  • 3) Due to insufficient lubrication, unreasonable lubricant selection, quality problems, aging and deterioration;
  • 4) Due to the large operating temperature difference between inside and outside, plus the improper selection of clearance, the external expansion is small and the internal interference is large, resulting in the sharp rise of bearing temperature;Key Points for Maintenance of IKO Bearing
  • 5) IKO bearing bears excessive load and uneven cutting load distribution, forming stress concentration;
  • 6) The surface of the parts is rough, resulting in poor contact or difficult oil film formation.
  • The morphological characteristics of burns can be judged by the small color of the surface. During the use of IKO bearing, due to lubricant, temperature, corrosion and other reasons, the surface of parts will change. The colors mainly include light yellow, yellow, brownish red, purple blue and blue black. 
  • Among them, light yellow, yellow and brownish red chips are discolored (see relevant contents later). If purple blue or blue black appears, it can be considered as burn. Burns are easy to cause the hardness of the surface of parts to decrease or micro lines to appear.Key Points for Maintenance of IKO Bearing
  • In terms of bearing speed, the bearing is determined according to the type, size, accuracy, cage type, load, lubrication mode, cooling mode and other factors.Key Points for Maintenance of IKO Bearing
Key Points for Maintenance of IKO Bearing
  • The installation and disassembly of bearings need to be removed and installed frequently in specific applications to ensure that they can be tested and repaired according to their location.
  •  Bearings with separate inner and outer rings, such as cylindrical bearing, needle roller bearing and conical bearing, are very suitable for this occasion. With the help of the shaft sleeve, the installation procedure of the taper hole type self-aligning ball bearing and self-aligning roller bearing is also simplified.Key Points for Maintenance of IKO Bearing
  • In some cases, preloading shall be applied to the rolling bearing to increase the rigidity. This procedure is usually used for the offset of the inner and outer rings of deep groove ball bearing, centripetal thrust ball bearing and tapered roller bearing, shaft bending, the change of tolerance of shaft or bearing housing, and the wrong fit will lead to the eccentricity of the inner and outer rings.Key Points for Maintenance of IKO Bearing
  •  In order to prevent excessive eccentric angle, self-aligning ball bearing, self-aligning roller bearing or self-aligning bearing seat are better choices. Voice frequency and torque, dynamic bearings are manufactured according to high-precision standards, so voice and torque are small.
  •  Deep groove ball bearings and cylindrical roller bearings are used for occasions with special requirements for low voice and low torque.Key Points for Maintenance of IKO Bearing
  • Key Points for Maintenance of IKO Bearing
  • (1) Note that the bearing with seal can not be cleaned by this method. The inside of the seal should be as it is and can not be cleaned.
  • (2) The assembly surface shall be cleaned with clean gasoline, kerosene, toluene or xylene solution, wiped dry with clean cloth, and then coated with a thin layer of smooth oil, so as to make the operation of the device convenient and efficient.Key Points for Maintenance of IKO Bearing
  • (3) When facing the device, open the bearing package, immerse it in the above gasoline and other liquids, and rotate it gently by hand. Ensure that the sealing oil on the surface of the holder, rolling element and raceway is completely cleaned.
  • (4) When cleaning a large number of bearings, first pour hot engine oil with a temperature of 90 ~ 100 ℃ to condense the sealing oil. At the same time, dig out all the old oil with a seamless tool without falling debris, then pour hot for a few minutes, then wash the oil with kerosene, and then wash it with gasoline. After cleaning, wear film gloves and put the bearing on a clean cloth or paper on the workbench to dry.
Technical requirements for Timken non-standard bearing

IKO Bearing

IKO is the first company in Japan to start the development of needle roller bearing technology. Now it is a leading manufacturer and has made many notable achievements in this field. Needle roller bearings containing thin needle rollers change the traditional image of bearings using round balls. Compared with ball bearings and other roller bearings, it is small in size and light in weight, but has a large load-carrying capacity. Needle roller bearings help make the overall equipment more compact, thereby saving money and resources. They are widely used in a wide range of applications such as motorcycles, industrial machinery and office automation equipment, where they have proven to be very reliable.

Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.

Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.

Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.

For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.

The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.

In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.

After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.

This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.

When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.

The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.

Lubricants have five basic functions for bearings:

Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants

We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
