Manufacturer profiles associated with Locating Pin.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
While both are cylindrical pins, locating pins are specifically designed for precision positioning in fixtures with tighter tolerances and often feature chamfers or reliefs for easier insertion. Dowel pins are typically used for permanent alignment of machine components.
Select based on workpiece hole size, required precision, and load conditions. Use slip fits (H7/h6) for easy insertion or transition fits (H7/k6) for more precise location. Consider diameter-to-length ratio for stability.
Standard steel pins are suitable up to approximately 200°C. For higher temperatures, consider stainless steel (up to 400°C) or specialized alloys. Thermal expansion coefficients must be considered for precision applications.
