*1: Correction of rated torque due to load fluctuation is not required. If ambient temperature exceeds 30°C, be sure to correct the rated torque with temperature correction factor shown in the following table.
The allowable operating temperature of XGS-CS is -20°C to 80°C.
※ The shaft's slip torque may be smaller than the coupling's rated torque depending on the shaft bore. ⇒Slip torque

Easy to mount and remove screws.Internal Structure
The designed shape of vibration-absorbing rubber achieves high torsional stiffness and high torque according to the finite element method. This product also succeeds in elongating its life by evenly dispersing the stress focusing on around the inner diameter of the jaw throughout the entire jaw.Material/Finish

Selection Based on Shaft Diameter and Rated Torque
The area bounded by the shaft diameter and rated torque indicates the selection size.Selection Example
In case of selected parameters of shaft diameter of φ19 and load torque of 7 N•m, the selected size is XGT-39C.Selection Based on the Rated Output of the Servomotor

Eccentric Reaction Force
This is the force generated when placing XGTXGLXGS in an eccentric condition. As the eccentric reaction force becomes smaller, the force acting on the shaft bearing also becomes smaller.Thrust reaction force
This is the force generated when compressing XGTXGLXGS in the axial direction. As the thrust reaction force becomes smaller, the force acting on the motor also becomes smaller.Change in static torsional stiffness due to temperature
This is a value under the condition where the static torsional stiffness at 20°C is 100%.Changes in the static torsion spring constant within the operating temperature are shown in the graph.
Before using the unit, be aware of the deterioration of responsiveness.
