CNC Machined Side-Slot Positioning Shaft Collar

Designed to meet the radial positioning and anti-rotation requirements of rotating shaft systems in automation modules, this cylindrical component features a lateral U-shaped slot and threaded holes on the end face. It is commonly used as a coupling connector or a locating pin seat for tooling fixtures. Its unique split-slot design allows the part to clamp onto a smooth shaft via radial contraction force generated by side screws during assembly. This achieves rigid torque transmission without keys, effectively preventing relative sliding or circumferential slippage during high-speed operation.

The core of the manufacturing process lies in ensuring the coaxiality between the outer diameter and inner bore, as well as the parallelism of the split slot sides. This guarantees uniform clamping force distribution and smooth motion after assembly. Due to the machining of multi-faceted features (such as side screw holes and end-face counterbores), high-rigidity CNC machining centers are employed for multi-step fixturing. Special attention is paid to the positional tolerance of each mounting hole relative to the central axis to prevent assembly interference or uneven stress caused by hole deviation.
