・Key groove shape complies with new JIS standards.Special key grooves should be shown in separate drawings.
・For d1 and d2,ordera for hole diameters other than the standard values can be made.
・Feel free to consult us about custom orders.
・combinations of set screw and clamp styles can also be costomized.

 ・If the torque applied to the coupling is small,wear is suppressed. Even if the eccentricity is somewhat large,the amount of wear will not increase.

・Heat resistance(ambient temperature): -30℃ to 80℃.

・When the hole diameter exceeds dimension d3 characteristics such as the rated torque may deteriorate.
・Maximum permissoble eccentricity and declination are not guaranteed to be used under rated torque. The amount of eccentricity and declination affects the speed of wear, by synergistic with the operating torque and rotating speed.
