The AirTAC AirTAC MBL50X160SU Mini Cylinder | 50mm Bore 160mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 160mm 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 MBL50X160SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 50mm bore and 160mm stroke, it generates 981N of push force at 0.5 MPa. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight body that is not designed to be disassembled like a traditional tie-rod cylinder. This specific SKU includes the U flat-end back cover for rigid fixed mounting and a built-in magnet (-S) for position sensing.
Inside, a heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel piston rod features 20μm hard-chrome plating to resist wear and corrosion. The integrated magnet enables seamless integration with AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches to detect rod position along the 160mm travel. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Provides 981N of push force at 0.5 MPa to eject small plastic parts from injection molds, fitting easily into tight tooling spaces where larger tie-rod cylinders cannot.
Uses the 160mm stroke to push product cartons onto a secondary packaging lane, relying on the rigid U flat-end back cover to withstand repetitive lateral shifting.
Moves a testing probe 160mm into position over printed circuit boards, using the -S magnet with a DMSG solid-state switch for precise end-of-stroke confirmation.
This 50mm bore provides 981N push and 881N pull at 0.5 MPa. If your application requires less force, step down to the 40mm bore (628N push at 0.5 MPa); if you need more power, the 63mm bore offers 1558N push. The fixed rubber bumper suits standard cycling, but for heavier moving masses at higher speeds, upgrade to the MBLC variant for an adjustable air cushion. Because this is a double-acting cylinder, it does not hold position or load when air pressure is lost or the valve is centered—you must add an external rod lock or pilot-operated check valve for fail-safe load holding.
The 160mm stroke pushes a Ø16mm rod a significant distance from a compact body, which lowers side-load tolerance. For this length, ensure the load is guided externally to prevent rod-bearing bending. Replacement parts must match the 50mm bore, 160mm stroke, G1/4 port size, PT tapered thread form, U flat-end back cover, and the -S magnet configuration.
Quick checklist
This 50mm bore cylinder delivers 981N push and 881N pull at 0.5 MPa, and 1374N push at 0.7 MPa, with a maximum theoretical force of 200kgf at 1.0 MPa. It operates at a speed of 30-800 mm/s.
No, the base MBL50X160SU uses a fixed rubber bumper to soften end-of-stroke impact. It does not have an adjustable cushion screw. If you need adjustable air cushioning for heavier loads, select the MBLC variant.
