Specifications:
The datasheet provides specifications for plastic bellows couplings, detailing models CHP-20, CHP-26, and CHP-34. Key parameters include nominal and maximum torque, misalignment tolerances (parallel, angular, axial), maximum rotation speed, static torsional stiffness, moment of inertia, and mass. Notably, static torsional stiffness values are measured at 20°C, and moment of inertia and mass are specified for the minimum bore diameter.

Dimensions:
Dimensions for each model are provided, including minimum and maximum bore diameters, overall dimensions (D, L, L1, F), and set screw specifications. The CHP-20 model features a set screw angle of 120° for a 3 mm bore.

Standard Bore Diameter:
The datasheet lists standard bore diameters for each model, with CHP-20 supporting diameters from 3 to 8 mm, CHP-26 from 6 to 13 mm, and CHP-34 from 8 to 18 mm. The recommended processing tolerance for paired mounting shafts is the h8 class.

Ordering Information:
To place an order, specify the bore diameter and size, such as CHP-26 8-8. The material composition includes an aluminum hub and a polyester resin bellow.
