Industrial Gas Springs – Pull Type
GZ-28-550-V4A

Very low progression rate with FDA approval

Valve Technology, Stainless Steel
Traction force max. 1,200 N
Stroke 550 mm

Brilliant performance when things become tight: For specific use e.g. in tough surroundings or small spaces, the broad spectrum of ACE industrial pull type gas springs made of stainless steel with body diameters from 15 mm to 40 mm supplements the comprehensive programme of the ACE industrial pull type gas springs with valves.

This high quality design is rust free and is more robust against environmental impact compared with standard gas pull type springs. These stainless steel gas springs are also optically appealing, very durable and available, upon request, in many stroke lengths and are also possible in many traction forces in combination with the suitable stainless steel accessories.
