What Are Pneumatic Air Rubber Bellows?
Air bellows are ideal for single-acting, short-stroke, high-thrust actuators. They are made of fabric-reinforced synthetic rubber and are available in single, double, or triple configurations, depending on the stroke and model. They contain no reciprocating metal parts, allowing for virtually frictionless thrust compared to conventional cylinders.
- 10 sizes, diameter 70-660 mm
- Stroke 45 to 375 mm
- Single, double or triple turn
- High thrust, frictionless motion
- Maintenance-free
