⚙️product introduction:
51104 is a thrust ball bearing, a type of rolling bearing specifically designed to withstand axial loads (forces acting along the axis direction). Its structural design enables it to withstand significant axial forces within a relatively small space, but it is generally not suitable for withstanding radial loads.
Basic structure: The thrust ball bearing is composed of an inner ring, an outer ring, and balls and a cage assembly. The inner ring and the outer ring can be separated. During installation, they can be respectively matched with the shaft and the bearing housing, providing high flexibility.

Load-bearing Capacity: Can only withstand axial loads, cannot withstand radial loads; single-direction bearings can only be subjected to force in one direction, while double-direction bearings can be subjected to force in both directions.
Speed Limit: Due to structural limitations (the centrifugal force of the rolling elements is relatively large), the maximum speed is relatively low, and it is usually suitable for medium and low-speed applications (the speed is generally in the range of several thousand revolutions per minute).
Installation Convenience: The shaft ring and the seat ring can be separated, making installation and disassembly easy, especially suitable for scenarios where the misalignment between the shaft and the bearing seat is relatively small.
Friction Coefficient: The rolling friction coefficient is small, resulting in higher operating efficiency, but it requires higher installation accuracy. If the installation deviation is too large, it will accelerate wear.
