The AirTAC AirTAC MBL40X80U Mini Cylinder | 40mm Bore 80mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 80mm 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 MBL40X80U is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 40mm bore and an 80mm stroke, generating 628 N of push force and 528 N of pull force at 0.5 MPa. The U-type flat-end back cover provides a rigid fixed rear mounting surface, making it ideal for straightforward inline pushing tasks.
Unlike tie-rod bodies, this unit utilizes a riveted rolling-packed aluminum barrel that crimps the covers directly to the tube for an ultra-light, compact footprint. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion, paired with a heterogeneous two-way piston seal that retains grease for a long service life. Because this specific SKU lacks the -S suffix, it cannot be fitted with a CMSG, DMSG, or EMSG position sensor.

Provides 628 N of push force at 0.5 MPa to reliably fold heavy corrugated cardboard flaps on continuous packaging lines where space is restricted.
Executes 80mm stroke movements to open and close CNC lathe safety doors, benefiting from the rigid U-type flat-end mounting for stable inline actuation.
Ejects machined aluminum parts from pallet stations, utilizing the 20 um hard-chrome plated rod to withstand repetitive, low-friction ejection cycles.
This 40mm bore provides 628 N of thrust at 0.5 MPa. If your assembly needs less force, stepping down to the 32mm bore yields 402 N of push force; if you require more power, the 50mm bore provides 981 N. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion—choose the MBLC variant if your 80mm stroke cycle requires precise end-of-stroke deceleration for heavier moving masses.
This cylinder cannot hold a load if air pressure is lost or the valve is centered; the rod will drift. Use an external pilot-operated check valve or a dedicated rod lock for fail-safe vertical positioning. For exact replacements, match the 40mm bore, 80mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and no built-in magnet.
Quick checklist
At 0.5 MPa, the MBL40X80U provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. You must select an MBL40X80S variant to enable electronic or reed switch position detection.
