OPTIMIZING EZ STACK FOR WIDE CENTER PORTION: ADAPTER PLATE ADD-ON
The EZ Stack Ball Screw Centering Device comes with a bearing housing floating plate that protects the lead screw from damage if the center section of the mold sags (2mm max). As an option, the nut housing plates can be added. These plates extend inwards from the ejector halves, repositioning the ball screw nuts closer to the center. This design increases the ejection stroke, providing more clearance for robotic part removal while maintaining stability and alignment. To avoid rubbing, a relief cut in the center portion of the mold is required for clearance. This add-on makes EZ Stack even more adaptable, optimizing performance for molds with larger center sections.
Adapter Plate Mounting Options:
The EZ Stack adapter plates can be mounted using two methods: direct mounting and flush mounting . In direct mounting, the adapter plates are screwed onto the mold surface, providing a simple and quick installation. In flush mounting, the plates are recessed into a pocket within the mold, creating a flush surface for the EZ Stack to be mounted on top, ensuring a more compact and integrated setup.

Floating Nut
The bearing housing adapter plate includes floating nuts to prevent excessive load transfer to the ball screw shaft . In wider molds, the center portion’s weight may cause sagging, which could stress the assembly. The floating nuts allow natural adjustment, ensuring smooth operation and extended system durability.
