619/6-2Z

The 619/6-2Z is a single-row double-sided deep groove ball bearing with dust covers. Its core function is to provide high-speed, low-maintenance, and bidirectional dust-proof rotational support for small-sized precision equipment and multi-condition general scenarios. With a mini size of 6mm inner diameter, 15mm outer diameter, and 5mm width, it can precisely fit into the installation space of equipment components with limited space. The two-sided non-contact dust cover structure can firmly lock the pre-filled lubricating grease and completely block dust, water vapor, and other impurities from entering the internal raceway. Compared to single-sided dust-proof models, it offers more comprehensive protection, is suitable for complex working conditions with a large amount of dust and impurities, and significantly extends the maintenance-free period of the bearing. It is made of high-hardness bearing steel, with a basic rated dynamic load of 0.884kN and a basic rated static load of 0.27kN. It can stably withstand radial loads and bidirectional axial loads. After the raceway is finely ground, the running noise and vibration are extremely low. The reference rotational speed can reach 100,000r/min, and the maximum rotational speed is 50,000r/min. It can meet the performance requirements of various small-sized high-speed rotating components. The pre-lubrication design makes it almost require no additional maintenance, effectively reducing the equipment operation and maintenance costs. This bearing is widely applicable in various scenarios, including small transmission structures of industrial equipment such as cutting equipment, surface mounters, and milling machines, as well as auxiliary rotating components of general machinery such as high-speed motors, gear pumps, and blowers. It can also be applied to civilian scenarios such as internal precision mechanisms of household appliances, toy accessories, and small electrical components of automobiles, and can meet the usage requirements of light-load high-speed daily leisure products such as bicycles and roller skates. In scenarios with basic requirements for protection and rotational speed, such as new energy photovoltaics and small instruments and meters, it can also play a stable supporting role. It is a universal small-sized bearing that combines practicality and economy.
