The AirTAC AirTAC MBL50X225SU Mini Cylinder | 50mm Bore 225mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 225mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL50X225SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa across its 225 mm stroke. The riveted rolling-packed barrel crimps the front and back covers directly to the tube, yielding a light, compact body that is not designed to be disassembled or rebuilt like a standard tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for rod position detection via AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches. The carbon-steel piston rod features a 20 um hard-chrome plating for wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life. The rear U flat-end cover provides a rigid, fixed mounting surface.

Drives a 225 mm capping head descent on a rotary bottling line, using the 981 N push force to securely seal beverage caps without crushing the plastic threads.
Folds heavy corrugated cardboard flaps on a packaging conveyor, where the 881 N pull force retracts the arm swiftly in a confined machinery footprint.
Ejects small aluminum stamped parts from a shallow die, relying on the built-in -S magnet and a DMSG solid-state sensor to confirm part clearance before the press cycles.
Stepping down in bore size, the 40 mm neighbor provides 628 N push at 0.5 MPa, which may suffice for lighter loads. If your application requires more force, the 63 mm bore steps up to 1558 N. Because this is a 225 mm stroke, the small 16 mm rod has low side-load tolerance; long unsupported strokes risk bending the rod bearing under lateral stress. Manage this by using an external guide rail, or switch to the MBLD double-rod type for anti-rotation. The base MBL uses a fixed rubber bumper, not an adjustable air cushion—if you need end-stroke speed damping for heavier moving masses, select the MBLC variant. A plain MBL does not hold its load when air pressure is lost or exhausted; the rod will drift. Use an external rod lock or pilot-operated check valve if position holding is critical. This SKU features a 50 mm bore, 225 mm stroke, G1/4 port, PT thread form, U flat-end back cover, and a built-in magnet.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, the base MBL50X225SU uses a fixed rubber bumper on the end caps to soften impact, not an adjustable cushion screw. If your 225 mm stroke moves a heavy mass and requires adjustable end-of-stroke deceleration, select the MBLC variant, which features an adjustable air cushion.
