Note: The inner holes at both ends of the coupling can be freely combined with the minimum and maximum inner diameters. The inner diameter sizes marked in the table are for reference only. The hole diameter required by the customer is also for reference only. For the hole diameter required by the customer, please contact us.

Note: The above inertial torque and technical parameters are measured by the standard of maximum aperture. The maximum rated torque value 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.
