Service Life of a 90-Degree Pneumatic
Actuator
The service life of a 90-degree pneumatic
actuator depends on multiple factors, but well-maintained units typically last
500,000 to 1,000,000 cycles or 10–20 years in normal conditions.
Key Factors Affecting Lifespan:
Quality of Construction – Actuators with
stainless steel components and high-grade seals (e.g., NBR, Viton) last longer.
Operating Conditions –
Harsh environments (high temperature,
corrosive chemicals, dust) reduce lifespan.
Clean, dry air (with proper filtration)
extends longevity.
Cycle Frequency – Frequent cycling (e.g.,
thousands per day) accelerates wear on seals and bearings.
Maintenance – Regular lubrication, seal
replacement, and air system checks prevent premature failure.
Signs of Wear & Replacement Needs:
Air leaks (damaged seals)
Slow or jerky movement (piston wear)
Corrosion or physical damage
Extending Service Life:
Use filtered, lubricated air (40µ
filtration recommended).
Select appropriate materials (e.g.,
stainless steel for corrosive settings).
Follow manufacturer maintenance schedules.
With proper care, a pneumatic actuator can
operate reliably for decades in industrial applications.
