7210Ace Stainless Steel Shock Absorbers.

Ace Controls


Based on the successful damping technology of the MAGNUM-Series, ACE offers this self-adjusting industrial shock absorber in complete stainless steel design. On the Ace stainless steel shock absorbers, all outer parts, such as outer body, stop collar, and main bearing are manufactured of V4A (material spec. number 1.4404). The MAGNUM VA series is therefore ideally suited for applications within the fields of medical technology, the food industry, electronics and the marine and associated industries. The MAGNUM VA series offers all the proven advantages of the MAGNUM standard series, like its robust and most modern seal technology, the highest energy absorption in a compact design, an integrated mechanical stop, and a wide range of effective weights. This series is available in thread sizes M33 x x1.5 to M64 x 2 with stroke lengths of up to 100mm. The MAGNUM VA series also offers a rod button made of V4A with a polyurethane element to reduce noise levels. Additionally, all MAGNUM VA dampers are filled with a special oil that conforms to the approval requirements (NSF-H1) of the food industry ex stock.
