The AirTAC AirTAC MBL40X75SCA Mini Cylinder | 40mm Bore 75mm 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 MBL40X75SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where traditional profile bodies cannot fit. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force across its 75 mm stroke, making it well-suited for medium-duty positioning tasks. The riveted rolling-packed barrel keeps the body light and compact, permanently crimping the front and rear covers to the tube for a sealed, maintenance-free assembly that is not designed to be disassembled like a tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, and EMSG sensor switches to detect rod position. It features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, rather than a rigid flat-end mount. The carbon-steel piston rod is treated with 20 um hard-chrome plating for wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Swings a 75 mm stroke arm to sort medium-weight cartons on a packaging line, utilizing the 628 N push force and the CA pivot cover to absorb lateral stress during arc routing.
Actuates a pivoting takedown lever on a weaving machine, where the CA clevis allows the rod to swing naturally with the mechanism's arc while maintaining consistent tension.
Lowers a threaded capping head onto glass bottles, using the -S magnet and a DMSG solid-state sensor to confirm cap seating before the 528 N retraction pull lifts the head.
If your application requires less force, stepping down to the 32 mm bore provides 402 N of push at 0.5 MPa, while moving up to the 50 mm bore yields 981 N for heavier payloads. Because this is a 75 mm stroke, side-load bending on the 16 mm rod is minimal, but for longer arcs the CA pivot cover inherently helps absorb radial stress. To manage end-of-stroke energy, note that this base MBL uses a fixed rubber bumper; for adjustable air cushioning to handle faster cycling or heavier masses, specify the MBLC variant. Keep in mind the rubber bumper only softens impact and does not hold the load—if air pressure is lost or the valve is centered, the rod will drift and drop, requiring an external pilot-operated check valve for position holding. Replacement units must match the 40 mm bore, 75 mm stroke, G1/4 port, PT thread form, CA pivot back cover, and -S magnet.
Quick checklist
At 0.5 MPa this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa the push force increases to 880 N, with a maximum theoretical force of 128 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa and runs at speeds of 30-800 mm/s.
No, the base MBL40X75SCA features a fixed rubber bumper to soften end-of-stroke impacts and cannot be adjusted. If your application requires adjustable air cushioning to handle heavier moving masses or faster cycle times, you must specify the MBLC variant.
