・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.

・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.

・Maximum rotational speed corresponds to no parallel misalignment (that is less than 1/10 of allowable value).

・There is a possibility of slip occurreng when a high transmission torque is loaded. For thisreason,it may be neceaasry to process the key groove.
