Matters needing attention affecting the service life of NTN cylindrical roller bearings

NTN cylindrical roller bearings are designed to handle high radial loads and perform well at high speeds. These bearings have a cylindrical shape and include a cage that retains the rollers in place.
NTN cylindrical roller bearings are available in different designs, including single-row, double-row, and multi-row configurations. They come in various sizes and are made from high-quality materials, such as stainless steel or ceramic, for added durability and longevity.
NTN cylindrical roller bearings offer a high resistance to wear and tear, making them a reliable solution for applications where heavy radial loads are present. These bearings have low friction coefficients, meaning that they operate at higher speeds with less energy consumption.
Overall, NTN cylindrical roller bearings are a reliable option for applications that demand high performance and efficiency.

NTN Cylindrical Roller bearings are precision parts and need to be handled with care. No matter how high-performance cylindrical roller bearings are used, if they are not used properly, the expected high performance cannot be obtained. The following are some precautions for the use of bearings.
Keep the NTN Cylindrical Roller bearings and its surrounding environment clean: Even if fine dust invisible to the naked eye enters the NTN Cylindrical Roller bearings, it will increase the wear, vibration and noise of the bearing. ntn Cylindrical roller bearings and their surrounding accessories should be kept clean, especially dust, dirt, tools and working environment.
Careful use and installation: Do not hit hard, hit the bearing directly with a hammer, and do not transmit pressure through the rolling elements. Influence of Precautions on Service Life of NTN Cylindrical Roller Bearings
Use the correct installation tools: Try to use special tools such as special heaters and pullers, and try to avoid using cloth, short fibers and other items.
Prevent bearing corrosion: When you take the bearing directly by hand, be sure to wash off the sweat on your hands and apply high-quality mineral oil before operation. Pay special attention to rust prevention during the rainy season and summer. However, under some special operating conditions, cylindrical roller bearings can obtain a longer life than traditional calculations, especially under light load conditions.

The prerequisite for these special operations is when the rolling surfaces (rails and rolling elements) are effectively isolated by a lubricant film and limit possible surface damage from contamination. In fact, under ideal conditions, so-called permanent bearing life is achievable.
There are many factors that affect the service life of NTN bearings, which can be roughly divided into use factors and internal factors.
The use factor mainly refers to whether the installation, adjustment, use and maintenance, maintenance and repair meet the technical requirements. The installation condition is one of the most important factors in the usage factors.
Improper installation leads to changes in the stress state between the parts of the whole set of cylindrical roller bearings. NTN bearings run under abnormal conditions and end their service life ahead of time. Intrinsic factors mainly refer to the three factors that determine the quality of bearings, such as structural design, manufacturing process and material quality.
The manufacture of bearings generally goes through multiple processing steps. The rationality, advancement and stability of all processing techniques will also affect the life of the bearing. The heat treatment and grinding processes that affect the quality of finished cylindrical roller bearings are more directly related to the failure of NTN bearings.
