Application Summary AI generated

GB/T 12360-1990 specifies the system of cone fits, defining tolerance zones, clearance, and interference for conical surfaces used in mechanical assemblies. It is applied in the design and manufacturing of machine tools, automotive components, and precision instruments where conical connections require controlled axial displacement and self-centering properties. The standard ensures interchangeability and reliable load transmission in applications such as taper shanks, valve seats, and hydraulic couplings.
