Coiled Spring Shaft

Designed for secure press-fit applications, these pins feature a central knurled body flanked by smooth cylindrical ends. The textured middle section provides enhanced retention force within housing bores or mating components, while the polished tips facilitate easy insertion and precise alignment during assembly.

Manufacturing focuses on maintaining strict concentricity between the knurled diameter and the end shafts to ensure smooth installation without binding. Consistent knurl pitch and depth are critical for achieving uniform holding power across batches. Surface finish requirements typically demand burr-free transitions to prevent damage to mating holes or O-rings in dynamic environments.

Production leverages CNC turning capabilities to achieve tight tolerances on shaft diameters and overall length. The facility supports various steel grades, including carbon and alloy steels, and can apply surface treatments such as blackening or zinc plating for corrosion resistance based on operational needs. Detailed 2D drawings specifying material standards and tolerance classes are required for accurate quoting and process planning.
