For example, IKO’s needle roller bearings have made major breakthroughs in load-bearing capacity and lifespan, significantly improving the operating efficiency and reliability of equipment.
Precautions for cross interchange of IKO bearings
Specifications match
When exchanging bearings, it is necessary to ensure that the specifications of the old and new bearings completely match, including inner diameter, outer diameter, width, sealing form and other parameters. If the specifications do not match, it may cause difficulty in bearing installation or affect the normal operation of the equipment.
load capacity
Different brands of bearings may have differences in design and material selection, so even if they are the same size, their load capacities may be different. When exchanging bearings, you need to ensure that the replacement bearing can handle the actual load of the equipment.
working environment
Different bearings may have different characteristics in terms of temperature resistance, corrosion resistance, etc. When selecting replacement bearings, it is necessary to consider the working environment of the equipment and select bearings with appropriate materials and characteristics to ensure long-term stable operation of the equipment.
Lubrication requirements
Different brands of bearings may have different lubrication requirements. When exchanging bearings, appropriate lubricants should be selected according to the lubrication requirements of the bearings, and lubricated as required to ensure normal operation and life of the bearings.
Case study of IKO bearing interchange
Case 1: Bearing exchange in the automobile manufacturing industry
An automobile manufacturing company used a batch of IKO needle roller bearings (model: NA4903) in the production process. Due to supply chain issues, companies need to find alternative bearings. After referring to the cross-exchange table, the company selected SKF’s RNA4903 bearing as a replacement. After testing, SKF bearings were equivalent to IKO bearings in terms of load capacity and service life, and seamless replacement was successfully achieved, ensuring the normal operation of the production line.
Case 2: Bearing exchange in the machining industry
A machining company’s equipment originally used IKO’s TA1510Z bearings. Since the supplier was unable to supply the bearings in time, the company needed to find alternative products. After referring to the cross-interchange table, the company selected NSK’s HK1510 bearings. By comparison, NSK bearings are not much different from IKO bearings in terms of wear resistance and vibration resistance, and they have been successfully interchanged.
Conclusion
IKO bearings occupy an important position in the global market with their high quality and high reliability. Through the introduction of this article, we understand the types, code structure and advantages of IKO bearings compared with other brands of bearings. The bearing cross-reference table provides convenience for enterprises in practical applications, helping them to flexibly respond to supply chain changes, reduce maintenance costs, and improve production efficiency. When exchanging bearings, attention should be paid to factors such as specification matching, load capacity, working environment and lubrication requirements to ensure stable operation and long service life of the equipment.
