Deep groove ball bearings are widely used in various fields and are prone to wear, corrosion, and other issues under complex working conditions. Surface strengthening treatment technology can improve the hardness, wear resistance, and fatigue resistance of bearings without changing their core structure and accuracy. The core goal is to focus on the pain points of service, balance performance improvement and dimensional accuracy guarantee, and expand the range of adaptation to harsh working conditions and reduce selection costs. It is a key means to extend the service life of bearings and broaden their application scenarios.
Based on the bearing material and actual needs, mainstream surface strengthening processes have their own adaptation focuses. Physical vapor deposition (PVD) technology achieves high hardness and low friction coefficient by depositing TiN, DLC and other thin films, with both wear resistance and corrosion resistance. It is suitable for high-speed, low friction, and mild corrosion scenarios, such as precision instruments, household appliance motor bearings; Chemical heat treatment technology forms a gradually strengthening layer through processes such as carburizing and nitriding, balancing hardness and toughness. It is suitable for heavy loads, impacts, and complex working conditions in metallurgy, engineering machinery, and other industries.
Laser surface strengthening technology relies on precise heating and cooling to form a hardened layer. The strengthening area is controllable and the heat affected zone is small, which can maximize the accuracy of bearings and adapt to precision machine tools and other scenarios that require strict accuracy; Electroplating and chemical plating technologies have mature processes and controllable costs. By depositing hard chromium and nickel phosphorus alloy coatings, their wear and corrosion resistance can be improved, making them suitable for humid and light industrial environments. It is necessary to focus on controlling the adhesion of the coatings to prevent detachment.
Surface strengthening technology can significantly extend the service life of deep groove ball bearings, reduce equipment maintenance and shutdown losses, and broaden their adaptability to harsh working conditions, providing solid guarantees for the stable operation of equipment in various industries.
