Note: The inner diameters of the inner holes at both ends of the coupling can be freely combined from small to large. The inner holes are machined with H7 standard tolerance, and the inner diameter dimensions marked in the table are for reference only.Please contact us for detailed parameters of the aperture you require.
Technical parameter table Unit:mm
| Product model | Torque (N.m) | Allowable eccentricity (mm) | Allowable deviation angle (∠°) | Allowable axial deviation (mm) | Allowable rotational speed (RPM) | Static torsional stiffness (N.m/rad) | Moment of inertia (N.m) | Coupling weight (g) |

Note: The above inertia moment and various technical parameters are measured from the standard of large aperture to the value of large fixed torque, which is related to the durability of the coupling itself. The larger the outer diameter, the greater the force, and the smaller the outer diameter, the higher the allowable speed.
