U.S. Patent Multiple Insert Diameter Cost Cutting Coupling System

The YPKC Coupling System

The YPKC Coupling System, U.S. Patent No. 6,682,483, has one piece molded flexible body split sleeve flatted inserts.
Engineering plastic with 25% glass fiber obtains a very economic rotary shaft coupling with light weight, torsional rigidity, and zero backlash.

YPKC Couplings with flatted, split sleeve inserts, provide the easiest possible way to accommodate a change in shaft diamteres.
Unique one-piece molded construction isolates voltage differences between coupled shafts thereby preventing electro-corrosion.
