Make sure the assembly device can overcome the insertion force.
Minimize Compensator stiffness when handling light-weight or delicate parts.
Longer, heavier parts can usually tolerate a greater insertion force.
The 100 and 200 Series use three types of shear pads. The HCL-12 is the softest shear pad, while the HCL-11 is nearly as soft, but with a longer C-of-C. The HCL-13 is the stiffest shear pad with a C-of-C similar to the HCL-12. The 400 Series uses the HCL-13A.
The 000 Series Compensator uses two types of shear pads, HCL-01A2 and HCL-02A. The HCL-01A2 is the softest shear pad, The HCL-02A is stiffer axially and laterally.
Find the lowest stiffness model that is within the application's load capacity and near the optimum C-of-C.
