Square Cover cylinder SMC MB1/MDB1 series

The SMC MB1 / MDB1 is a square-tube type air cylinder, designed as a double-acting, single-rod actuator. It is widely used for general automation where durability, versatility, and compatibility with auto switches are required.

Key Specifications & Features SMC MB1 / MDB1

• Lightweight Design: Up to 10% lighter for bore sizes 50–100 mm thanks to optimized cover shapes.

• Bore Sizes: ø32, ø40, ø50, ø63, ø80, ø100, ø125 mm.

• Operating Pressure: Max. 1.0 MPa (proof pressure: 1.5 MPa).

• Speed Range: 50 to 1000 mm/s (piston speed).

• Temperature Range: –10 to 70 °C (–10 to 60 °C when equipped with switch).

• Cushion Options: Air cushion or rubber bumper, reducing vibration and extending cylinder life.

• Auto Switch Compatibility: Switches can be mounted on all four surfaces, with optional dust-preventing fasteners.

• Port Thread Types: Rc, NPT, G.

• Mounting Types: Basic, foot, rod flange, head flange, single/double clevis, and more.
