CF-X O2-C - CENTAFLEX - COUPLINGS - MIKIPULLEY VIETNAM

These models use high-quality nylon resin for the buffer material. This construction and element material mean they are rigid in the torsion direction, have excellent flexibility in the bending and axial direction, and have no backlash. They absorb vibration and shock while delivering accurate power transmission. These models have a simple construction comprised of element (buffer material), cylinder hub, flange hub, and a bolt for locking the element in place.

Structure and Materials

*Max. rotation speed does not take into account dynamic balance.

*Static torsional stiffness values given are from measurements taken at 20℃ .

*Values for moment of inertia and mass are those when the cylindrical hub and flange hub have the minimum bore diameters.

*The nominal diameters for bolts M1, M2, and M3 are equal to the quantity minus the nominal diameter of the screw threads, where the quantity for clamping bolt M3 is for a hub on one side.

*The recommended processing tolerance for paired shafts is the h7 class.
