⚙️Structural composition:
6304W17 is deep groove ball bearing, composed of an inner ring, an outer ring, steel balls and a cage.
Working principle: Deep groove ball bearings operate mainly based on the principle of rolling friction. When the shaft rotates, the inner ring rotates along with it, and the rolling elements roll in the grooves of the inner and outer rings. Due to the deep groove design of the grooves, the contact area between the rolling elements and the grooves is large, which can withstand large radial loads. The rolling friction between the rolling elements and the grooves replaces sliding friction, resulting in a lower friction coefficient for deep groove ball bearings, typically ranging from 0.001 to 0.005. At high rotational speeds, the generated heat is less, enabling them to meet higher speed requirements.

Low friction resistance: Rolling friction replaces sliding friction, resulting in extremely low friction resistance during operation of the deep groove ball bearing. This reduces energy loss and improves mechanical efficiency.
High rotational speed: It can operate stably at high rotational speeds, suitable for equipment requiring high-speed rotation, such as motors, fans, machine tool spindles, etc.
Load-bearing capacity: Primarily withstands radial loads, and can also withstand certain axial loads simultaneously. When increasing the radial clearance of the bearing, it has the performance of angular contact ball bearings, capable of bearing combined radial and axial loads. When high rotational speed is required but thrust ball bearings cannot be used, it can also be used to withstand pure axial loads.
Easy maintenance: The structure is relatively simple, with relatively low requirements for installation accuracy and lubrication conditions. The maintenance cost is low, and most models do not require frequent lubrication. During use, it is relatively worry-free.
Deep groove ball bearings have an extremely wide range of applications, covering various fields such as small power motors, automotive and tractor gearboxes, machine tool gearboxes, household appliances, instruments and meters, aerospace, medical devices, and many others.

| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
