The long-term stability of 440C stainless steel thin-section bearings represents the bearing's ability to maintain its original performance under continuous operation over a long period of time. Even if the initial accuracy meets the standard, the raceway will slowly wear under the continuous action of load, speed and environmental medium, which will gradually cause the rotational accuracy to decrease. Thin-walled ring structures are more sensitive to continuous stress, and long-term overload can cause irreversible deformation. The 440C material can reduce the risk of failure caused by rust, but it cannot completely avoid normal operation losses. Properly matching operating conditions and ensuring proper lubrication and sealing can slow down performance degradation and guarantee the long-term stable operation of bearings.
