Note: If additional keyways are required, they can be customized in non-standard form.Please add K after the model shaft diameter size. For example:GLG-68×75-20K×22K,means both inner holes have keyway openings.

External dimensions table     Unit:mm

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.The inner diameter dimensions marked in the table are for reference only. Please contact us for detailed consultation on the required aperture.

Technical parameter table      Unit:mm

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.
