Reduce the load on the work and equipment with the upper and lower springs!
The spring plunger is an accessory for vacuum pads used for height adjustment during suction and to mitigate impacts. The FSTA-HD series features a spring-loaded spring plunger that has springs both above and below the mounting position, allowing for adjustments when there are height restrictions during work elevation or when the mounting frame may bend due to high loads. Additionally, the rod of the main body is made of stainless steel, providing high durability and a long lifespan. There are three sizes available for stroke lengths ranging from 25mm to 90mm. (Note: Not all strokes can be utilized to prevent load and damage caused by contact between springs.) A type with a rotation prevention feature suitable for use with oval pads is also available (FSTA-HD-VG). For more details, please contact us or refer to the catalog.

basic information
【Features】 ○ Buffer Function → Reduces excessive load on the workpiece during pick and place. ○ Two Springs (Upper and Lower) → Accommodates excessive stroke when height restrictions are applied during workpiece ascent. Also allows for stroke correction if the mounting frame bends under high load (please refer to the diagrams in the catalog for details). ○ High-quality carbon bushings and stainless steel rods → Maintenance-free even with long-term use, and optimal for short cycle specifications. ○ Rotation prevention type (FSTA-HD-VG) is also available → Ideal for applications using oval vacuum pads. ● For more details, please contact us or refer to the catalog.
