Advantages of air spring used as an actuator
low cost
In general, the initial cost of a Guomat actuator for the same load capacity is half or less than that of a conventional pneumatic or hydraulic cylinder.
Wide range of sizes
Guomat actuators range in size from 85mm to 950mm in diameter. The carrying capacity is up to 450 kN, and the stroke can be as large as 355mm.
Eccentric bearing capacity
Guomat lifters are not affected by eccentric loads within certain limits. This is superior to conventional air or hydraulic cylinders. The eccentric load carrying capacity eliminates connecting rod bending, scratching, seal wear and other failures common to traditional air or hydraulic cylinders.
