The AirTAC AirTAC MBL50X125SCA Mini Cylinder | 50mm Bore 125mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 125mm 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 MBL50X125SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa, making the 125 mm stroke ideal for driving heavier slides or mid-stroke clamping arms. The riveted rolling-packed body keeps weight low and is permanently crimped, distinguishing it from rebuildable tie-rod designs. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear and corrosion.
This SKU includes the CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to absorb angular misalignment and arcing loads. The built-in magnet (-S) enables direct position detection using AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. End-of-stroke energy is absorbed by a fixed rubber bumper rather than an adjustable air cushion; for faster or heavier cycling, the MBLC variant provides screw-adjustable cushioning.

Swings a heavy sorting flap on packaging lines using the 981 N push force and CA clevis mount to accommodate the arcing motion smoothly.
Raises a stop blade on a roller conveyor; the 125 mm stroke clears tall pallets while the magnet enables a DMSG sensor to confirm retraction.
Folds thick corrugated container lids, leveraging the 1374 N push at 0.7 MPa to overcome hinge friction in compact packaging machinery.
At 0.5 MPa, this 50 mm bore generates 981 N of push force. If you need less holding power, step down to the 40 mm bore (628 N push); if your payload is heavier, step up to the 63 mm bore (1558 N push). The CA clevis mount is optimal here for pivoting mechanisms, whereas a flat-end U cover suits rigid dead-end pushing. The fixed rubber bumper softens end impacts but does not lock the rod—live air pressure is required to hold a load, so add an external pilot-operated check valve if the rod must not drift when air is exhausted. Porting is G1/4 with an M14x1.5 rod-end thread.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa the push increases to 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. The double-acting operating speed ranges from 30 to 800 mm/s.
The base MBL uses a fixed rubber bumper that cannot be adjusted; for adjustable air cushioning, select the MBLC variant. This model includes a built-in magnet (-S) and works with AirTAC CMSG, DMSG, and EMSG sensor switches for position detection.
