Reduce the load on the work/device 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 plunger with springs on both the upper and lower parts. This allows 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 stroke lengths can be used 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.
