The QLZE / QSZE / QST-KE) modular linear actuator from Nook Industries (Cleveland, OH) has a stainless steel cover band that wraps over the square aluminum profiles – creating an optimal solution to combat caustic wash-down issues. The stainless steel housing also protects the aluminum profile from exposure to damage due to clogging and pitting; thus protecting the deep structures of the extrusion and extending the system’s life. In addition, the stainless steel design requires no bellows to cover the extrusion which typically wears out over time. The actuator is suited for pharmaceutical/medical, clean room, food/beverage, packaging and petrochemical applications.
