■High performance (high torque, high rigidity) disc coupling
・Product with improved strength and rigidity than similar size general disc type (SD series) by improving the leaf spring (increasing support holes)
・Changing from the conventional 2-point fixing method to a 3-point fixing method increases durability and allows the use of smaller-sized products without compromising performance.
■Improved leaf spring shape
・Compared to 4-hole leaf springs, 6-hole leaf springs are somewhat less flexible, but increasing the number of support holes increases durability (=strength) by dispersing stress more.
・Rigidity is also improved due to narrow hole spacing
・Ideal as a disc coupling for high strength and high rigidity
Increased torque transmission force (durability, strength) compared to similar or same outer diameter size
■High torsional rigidity
Excellent responsiveness, high speed, high precision, ideal for positioning
