The MDBB40-50Z is a standard MB series cylinder manufactured by SMC. It features a double-acting, single-piston rod design, a 40mm bore, and a 50mm stroke.
Its key feature is a weight reduction of up to 10% achieved through a redesigned cylinder head, and it incorporates a built-in magnetic ring for position detection via a magnetic switch. This cylinder is widely used in industrial automation in the automotive, semiconductor, and electronics industries to drive linear reciprocating motion mechanisms.

Core Features
- ✓ Driven linear motion: Converts the pressure energy of compressed air into mechanical energy to drive the piston rod in reciprocating linear motion.
- ✓ Position detection capability: An internal magnetic ring, in conjunction with an externally mounted magnetic switch, enables electrical detection and signal feedback of the piston position.
- ✓ End-stroke buffer protection: An adjustable air buffer mechanism absorbs the impact when the piston reaches the end of its stroke, reducing vibration and noise.
- ✓ Lightweight design: Structural optimization achieves weight reduction, contributing to a decrease in overall equipment weight and energy consumption.

Frequently Asked Questions
Q: What type of automated equipment is this cylinder suitable for?
A: It is a general-purpose standard cylinder with a wide range of applications. It is commonly used in equipment requiring linear push-pull movements, such as automated production lines, packaging machinery, semiconductor manufacturing equipment, electronic assembly lines, robot peripherals, printing machinery, and food processing equipment.
Q: How is the piston position of this cylinder detected?
A: This cylinder model has a built-in magnetic ring in the cylinder body. You only need to install a suitable magnetic switch (such as the SMC D-M9 series) in the slot of the cylinder barrel according to your application requirements. When the piston with the magnetic ring moves to the switch position, the switch will send an electrical signal, achieving position detection and automatic control.
Q: What should I pay attention to during installation?
A: First, this model is a basic installation; you need to confirm that the reserved installation space and screw hole positions on the equipment match. Second, its piping diameter is Rc 1/4; you need to prepare the corresponding pneumatic connectors and pipelines. Finally, the piston rod end has an M14x1.5 external thread for connecting the load. When selecting rod end accessories (such as Y-type connectors), attention should be paid to the thread specification.
