The AirTAC AirTAC MBL50X250U Mini Cylinder | 50mm Bore 250mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 250mm 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 MBL50X250U is a double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body cannot fit. Operating at 0.5 MPa, it generates 981 N of push force and 881 N of pull force over its 250 mm stroke. The U suffix indicates a rigid flat-end rear cover, providing a solid fixed mounting footprint for straightforward linear thrust applications.
This SKU lacks the -S magnet suffix, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor switch. To survive long-term friction, the carbon steel piston rod features a 20 um hard-chrome plating, and a heterogeneous two-way piston seal actively retains grease. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion screw.

Pushes lightweight aluminum diversion arms on packaging conveyor lines using 981 N of thrust at 0.5 MPa, fitting cleanly within the 50 mm frame gaps.
Ejects populated PCB trays from wave soldering stations over a 250 mm travel distance, utilizing the fixed rubber bumper to soften the end-of-stroke tap.
Folds top flaps on small corrugated cartons prior to case sealing, where the rigid U flat-end back cover mounts solidly to the machine sub-frame.
If you need slightly less force, step down to the 40 mm bore (628 N push at 0.5 MPa). If your application requires heavier thrust, step up to the 63 mm bore (1558 N push at 0.5 MPa). Because this 250 mm stroke pushes a Ø16 mm rod, it is highly susceptible to side-load bending; you must use an external guide rail or pivot the load to prevent rod bearing failure. For faster cycle speeds with a heavy load, consider the MBLC variant which adds an adjustable air cushion. Note that this base MBL relies on live air pressure to hold its position—if pressure drops, the load drifts. A separate rod lock is required for fail-safe holding.
Replacement match: 50 mm bore, 250 mm stroke, G1/4 port, PT thread, U flat-end back cover, no magnet.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa push is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
This specific SKU lacks a built-in magnet, so CMSG, DMSG, or EMSG electronic switches cannot be fitted. It uses a fixed rubber bumper for end-of-stroke impact absorption; for adjustable air cushioning, select the MBLC variant.
