The AirTAC AirTAC MBL50X150SU Mini Cylinder | 50mm Bore 150mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 150mm 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 MBL50X150SU 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 over a 150 mm stroke, making it ideal for moving heavier small-scale loads. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight footprint that is not designed to be disassembled like a traditional tie-rod body.
This specific SKU features a built-in magnet (-S) for position detection via AirTAC CMSG (reed) or DMSG and EMSG (solid-state electronic) sensor switches. It uses a U flat-end back cover for rigid mounting and relies on a fixed rubber bumper to absorb end-of-stroke impact rather than an adjustable air cushion. The carbon-steel piston rod is treated with 20 um hard-chrome plating, paired with a heterogeneous two-way piston seal that retains grease for extended operational life.

Uses the 981 N push force at 0.5 MPa to deflect medium-weight product pallets on a tight 150 mm stroke within compact conveyor routing modules.
Provides reliable 150 mm extraction force to pull machined aluminum billets from a lathe chuck, fitting neatly into the limited clearance of the machine enclosure.
Drives a mechanical flap-folding arm on a packaging line, utilizing the built-in magnet to confirm retraction before the case sealer applies tape.
Select this 50 mm bore model when a 40 mm bore (628 N push @0.5 MPa) is underpowered or a 63 mm bore (1558 N push @0.5 MPa) is physically too large for your fixture. It provides 1374 N of thrust at 0.7 MPa. Because the 150 mm stroke is substantial for a mini cylinder, the relatively small Ø16 rod has limited side-load tolerance; use an external guide rail or consider the MBLD double-rod type to prevent rod bearing bending under offset loads.
This base MBL variant uses a fixed rubber bumper and cannot hold a load if air pressure is lost or the valve is centered—the rod will drift. For faster cycling with heavier moving masses, step up to the MBLC variant which offers adjustable air cushioning. The exact replacement match is: 50 mm bore, 150 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 double-acting cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, push force increases to 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. It operates at a speed of 30-800 mm/s.
The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (you would need the MBLC variant for that). However, this specific -S SKU includes a built-in magnet, allowing you to mount CMSG, DMSG, or EMSG sensor switches directly onto the cylinder body for rod position detection.
