The AirTAC AirTAC MBL50X30SU Mini Cylinder | 50mm Bore 30mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 30mm 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 MBL50X30SU is a double-acting aluminum mini round cylinder engineered for compact machines needing substantial force in a small footprint. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, making this 30 mm stroke variant ideal for short, powerful linear movements. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight machine spaces, though it is not designed to be disassembled like a tie-rod cylinder.
This configuration includes a U flat-end back cover for rigid mounting and a built-in magnet (-S) for position detection. The magnet interfaces directly with AirTAC CMSG reed switches or DMSG and EMSG electronic solid-state sensors. The carbon-steel piston rod features 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.

Uses the 981 N push force at 0.5 MPa to knock finished plastic parts from tight mold cavities where a larger ISO cylinder would not fit.
Actuates a short 30 mm stroke diverter arm on a packaging line, relying on the U flat-end cover for rigid, fixed mounting against side impact.
Moves an electronic test head into position, using the built-in magnet and a DMSG solid-state sensor to confirm rod extension for the control logic.
Generating 981 N at 0.5 MPa, this 50 mm bore cylinder fits medium-duty compact actuation. If you need less force, step down to the 40 mm bore, which provides 628 N of push force at 0.5 MPa. For heavier loads, step up to the 63 mm bore, delivering 1558 N at 0.5 MPa. Because the base MBL uses a fixed rubber bumper rather than an adjustable air cushion, choose the MBLC variant if your application requires end-of-stroke speed tuning. Keep in mind that a plain MBL does not hold its load when air pressure is lost; the rod drifts or drops, so add an external rod lock or pilot-operated check valve if position holding is required.
This exact SKU features a 50 mm bore, 30 mm stroke, G1/4 port, PT thread form, U flat-end back cover, and a built-in magnet for CMSG/DMSG/EMSG sensors. The 30 mm stroke keeps the Ø16 mm rod highly resistant to side-load bending, but always ensure the load is guided externally to prevent premature seal wear.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa the push force is 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. The operating speed ranges from 30-800 mm/s.
No, the base MBL50X30SU uses a fixed rubber bumper to soften end-of-stroke impact. It is not an adjustable air cushion and does not act as a brake. If you need adjustable cushioning for heavier moving loads, select the MBLC variant.
