The AirTAC AirTAC MBL40X75U Mini Cylinder | 40mm Bore 75mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 75mm 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 MBL40X75U is a double-acting aluminum mini round cylinder engineered for compact machinery requiring a 75mm stroke. At 0.5 MPa it generates 628 N of push force and 528 N of pull force, making it well-suited for mid-range actuation tasks. This SKU features a U flat-end back cover for rigid, fixed mounting and uses a standard PT tapered port thread. Because it lacks the -S magnet suffix, a position sensor cannot be fitted to this specific unit. The riveted rolling-packed barrel design permanently crimps the covers to the tube, yielding a lighter footprint than tie-rod alternatives but preventing field disassembly.
Inside, a heterogeneous two-way piston seal actively retains grease for long service life, while the carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion. End-of-stroke deceleration is handled by a fixed rubber bumper rather than an adjustable cushion screw; if your cycle demands heavier impact absorption, the MBLC variant offers adjustable pneumatic cushioning.

Pushes raw bar stock into the collet with 628 N of force, fitting neatly within the tight clearance of a lathe enclosure.
Folds corrugated cardboard flaps on a continuous flow wrapper using the rigid U flat-end mount to maintain strict perpendicular alignment.
Actuates a diverting gate to separate depanelized circuit boards, relying on the 75mm stroke to clear the conveyor path quickly.
This 40mm bore provides 628 N of thrust at 0.5 MPa. If your assembly needs less force, the 32mm bore offers 402 N of push force. For heavier payloads, stepping up to the 50mm bore yields 981 N. Keep in mind that the plain MBL design relies on live air pressure to maintain position; the rod will drift or drop if pressure is lost or the valve centers, as the rubber bumper softens impacts but acts as neither a lock nor a brake. For holding loads without live air, utilize an external rod lock or pilot-operated check valve.
For replacement, match the 40mm bore, 75mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and no-magnet configuration. Because the stroke is under 300mm, side-load stress on the 16mm rod remains manageable, but always ensure rigid U-mount alignment to avoid premature seal wear.
Quick checklist
This 40mm bore cylinder uses a G1/4 port and a 16mm rod. It outputs 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, with a maximum theoretical force of 128 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end impacts, not an adjustable cushion screw. If your application requires adjustable pneumatic cushioning for heavier or faster cycles, select the MBLC variant.
