PK Integrated Rigid Chain

Product Description

Compared to traditional ball screws, these systems offer several advantages, especially in applications requiring long strokes and compact storage. Some key benefits include:

Excellent Space Efficiency
The chain can coil or fold into a small magazine, unlike ball screws, which require extra space for the nut and drive end.
Capability for Very Long Strokes
Unlike ball screws, which may suffer from deflection and vibration, rigid chains can extend several meters or more.
Simplified Structure & Installation
No need for precise alignment or support structures, making installation more simple and easy.
Design Flexibility
Also applicable in tight spaces such as stage lifts, automated warehouses, and mechanisms that need to extend from confined areas.
