The MDBB80-300Z is a standard tie-rod cylinder from the SMC brand.
It features a double-acting design, an 80mm bore, a 300mm stroke, and an externally threaded piston rod with an internal magnetic ring for mounting a magnetic switch to detect piston position. Adjustable air cushioning devices at both ends effectively absorb piston impact energy, resulting in smoother operation.

Core Features
- ✓ Provides linear power: Converts the energy of compressed air into the linear reciprocating motion of the piston rod, used to push or pull objects.
- ✓ Double-acting action: Achieves active movement of the piston rod in both directions—expansion and retraction—through the alternating intake and exhaust of compressed air on both sides of the piston.
- ✓ Built-in magnetic ring for easy control: The built-in magnetic ring can work with an externally mounted magnetic switch to output a signal when the piston reaches a specific position, facilitating automated control.
- ✓ Smooth stop and buffer: The standard air buffer mechanism slows the piston speed at the end of the stroke, effectively reducing impact noise and mechanical vibration, protecting the equipment.

Frequently Asked Questions
Q: What are the maximum thrust and pull forces of this cylinder?
A: According to its technical specifications, under a standard operating pressure of 0.5 MPa, its theoretical thrust (when extended) is approximately 2520 N, and its theoretical pull force (when retracted) is approximately 2270 N.
Q: In what scenarios is it suitable for use?
A: It is a general-purpose standard cylinder widely used in industrial automation equipment requiring linear push-pull motion, such as in automotive manufacturing, semiconductors, electronics, machine tools, food packaging, printing, and medical devices.
Q: Can the MDBB80-300Z be fitted with a magnetic switch?
A: Yes. This model has a built-in magnetic ring (the "D" in the model number indicates a built-in magnetic ring), specifically designed for installing magnetic switches to detect piston position. For example, SMC's M9B and M9BW magnetic switches can be selected.
