CF-X [O1] Type
Power is transmitted via a backlash-free design featuring nylon resin elements. This design is rigid in the torsional direction and highly flexible in the lateral and axial directions, enabling precise power transmission while absorbing vibrations and shocks.The O1 type includes a nylon resin element, a cylindrical hub, and mounting bolts.

- The pilot hole is a drill hole. The minimum values for d1 and d2 indicate the minimum hole diameters specified in our standard hole machining specifications, while the maximum values indicate the largest hole diameters that can be machined.
- The designation for M1 and M2 bolts consists of the quantity followed by the thread size.
- The TK dimension refers to the bolt mounting pitch diameter of the flange hub or mating mounting surface.

- All specifications for diameters of 11 mm or less are identical to those listed in the "Old JIS Standards" column.
- The set screw and the keyway will not be on the same plane.
- The set screw is included with the product.
- The positional accuracy of keyway machining is checked visually.
- Please contact us if you require specific positioning accuracy for the keyways relative to each hub.
- For standard dimensions of hole patterns other than those listed here, please refer to the technical documentation.
