1. Coaxiality centering
Used for the installation and positioning of shaft-like and rod-like parts, ensuring that the axis of the coincides with the axis of the mounting hole, avoiding assembly errors that could lead to operation jams, vibrations, or wear.
Example: connection between the main spindle of a tool and the tool; assembly of the motor shaft and the coupling.
2. Assembly limit
Limits the installation depth or axial position of parts to prevent over-assembly or installation, ensuring the consistency of batch assembly.
3. Auxiliary guidance
Guides parts quickly into position during assembly, reducing the difficulty of manual assembly and improving assembly efficiency
