The HXP-123 is a self-centering two-/three-arm puller with an external hand pump, so the pulling force is generated hydraulically rather than by hand pressure on the arms themselves. Net mass is 11.7 kg, and the arm set can be configured for either two-point or three-point contact depending on the component being removed. The self-centering action keeps the puller aligned on the center axis while force is applied, which limits side load on the shaft during removal. Because the pump is external, the operator controls the pulling force from a distance from the arms, keeping hands clear of the load path when drawing off press-fitted or shrink-fitted parts.
