NCF213V Excavator Bearing: Excellent Performance Drives Efficient Operations​

In the high - intensity and complex working environment of excavators, bearings, as key components, directly affect the operational stability, efficiency and service life of the equipment. The NCF213V bearing is meticulously designed for heavy - duty construction machinery such as excavators. With its excellent design and outstanding performance, it has become a core component to ensure the reliable operation of excavators.

I. Unique Structural Design

The NCF213V is a single - row full complement cylindrical roller bearing. Its structure, which consists of a single rib on the outer ring and double ribs on the inner ring, has two advantages. On one hand, it can effectively bear one - way axial loads, meeting the axial force requirements generated by the excavator during operation due to digging force, steering force, etc. On the other hand, the full complement cylindrical roller layout maximizes the number of rollers in a limited space, greatly improving the radial load - carrying capacity. It can easily cope with the huge radial impact generated by the excavator's working device during digging and loading/unloading materials. In addition, the bearing adopts a special internal geometric structure, and the contact area between the rollers and the raceways is optimized. This not only reduces the friction resistance during operation and improves the rotation accuracy, but also enhances the buffering capacity against impact loads, ensuring stable operation under harsh working conditions.

II. Accurate Dimensional Parameters

  1. Inner diameter: 65mm. This size accurately matches the shaft diameter specification of the specific part of the excavator, ensuring a tight fit between the bearing and the shaft. It avoids relative sliding under high - speed and heavy - load conditions, enabling efficient and stable power transmission.
  1. Outer diameter: 120mm. Through careful design, the outer diameter provides sufficient structural strength for the bearing and perfectly fits the installation size of the relevant components of the excavator, ensuring the compactness and coordination of the entire mechanical system.
  1. Width: 23mm. The reasonable width design takes into account both the axial load - carrying capacity of the bearing and the space constraints of the equipment. While ensuring effective bearing of axial forces, it does not occupy too much installation space, meeting the requirements of the excavator for the compact design of components.

III. Excellent Performance

  1. Strong load - carrying capacity: By optimizing the number and size of the rollers, the NCF213V bearing has a strong radial load - carrying capacity. Although there is no exact public data on the rated dynamic load, referring to similar bearings, such as the NF213 bearing with a rated dynamic load of 73.2kN and the N213 bearing with a basic rated dynamic load (Cr) of 105kN, it can be inferred that the NCF213V performs well in radial load - carrying. It can easily cope with the huge radial force generated when the excavator is digging hard rocks, moving heavy objects, etc., effectively preventing damage due to overload and greatly extending its service life. In terms of axial load - carrying, relying on its special rib structure, although it is mainly designed to bear one - way axial loads, it also has a certain ability to resist two - way axial forces to deal with complex force conditions.
  1. Good rotation performance: Adopting high - precision roller and raceway processing technology, the rollers are stably positioned after radial self - locking, so that the bearing has an extremely low friction coefficient during operation and excellent rotation performance. Even in the high - frequency and high - load operation state of the excavator, it can ensure the stable and smooth operation of the equipment, reduce energy consumption and improve work efficiency.
  1. High reliability and stability: The NCF213V bearing is made of high - quality bearing steel. After strict heat treatment process, the hardness, strength and wear resistance of the material are significantly improved, enabling it to operate reliably in harsh environments such as high temperature, high pressure and heavy dust. At the same time, the optimized oil grooves (relief grooves) and rib guide surfaces are conducive to the uniform distribution of lubricating media, further improving the operational stability and reducing the probability of failures. The modified rollers and the raceways of the rings with a convex design can better compensate for alignment errors and alleviate stress concentration problems. Even if the excavator has assembly errors or shaft misalignment caused by vibration and impact during operation, the bearing can still work normally, greatly improving the overall reliability of the equipment.

IV. Excellent Environmental Adaptability

  1. Efficient dust - proof design: The excavator operation site is often full of flying dust. A large number of dust particles entering the bearing will accelerate wear and shorten its service life. The NCF213V bearing is equipped with an efficient sealing device, which can effectively block the invasion of dust and impurities, ensure the internal cleanliness, maintain a good lubrication state, and work normally even in extremely harsh dust environments.
  1. Excellent impact and vibration resistance: During excavation operations, excavators often face strong impacts and vibrations, which put high demands on the fatigue resistance of the bearing. The NCF213V bearing, with its solid structural design, high - quality materials and exquisite manufacturing technology, has excellent impact and vibration resistance. It can operate stably in environments with frequent impacts and vibrations, ensuring the continuity and reliability of the excavator's work.
  1. Wide temperature adaptation range: During long - term high - intensity operations, various components of the excavator will generate a lot of heat, leading to an increase in working temperature. When operating in cold areas, it also has to face the test of low - temperature environments. The materials and grease used in the NCF213V bearing have good temperature adaptability, and can maintain stable performance in a wide temperature range of - 40℃ to 120℃. Whether in hot desert areas or cold polar environments, it can ensure normal operation, meeting the usage requirements of the excavator under different working conditions.
The NCF213V excavator bearing, with its accurate structural design, excellent performance parameters and strong environmental adaptability, provides a solid guarantee for the efficient and reliable operation of excavators. It is an indispensable key component in the field of modern excavator manufacturing and maintenance, helping the construction machinery industry achieve efficient operations under various complex working conditions.
