The AirTAC AirTAC MBL40X65CA Mini Cylinder | 40mm Bore 65mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 65mm 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 MBL40X65CA is a double-acting aluminum mini round cylinder engineered for compact machinery where space is at a premium. Delivering a robust 628 N push force at 0.5 MPa, this 40 mm bore unit is built around a riveted rolling-packed barrel that crimps the covers directly to the tube, ensuring a lightweight footprint that is not designed to be disassembled like a traditional tie-rod body. The CA pivot back cover allows the cylinder to swing freely on a pin, making it uniquely suited for arcing and angular load applications that a rigid flat-end mount cannot accommodate.
Internally, the carbon steel piston rod features a 20 µm hard-chrome plating for high wear and corrosion resistance, 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 accept a CMSG, DMSG or EMSG position sensor. The end-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure is lost.

Uses the CA pivot mount to swing a 65 mm stroke diverter gate on a packaging line, leveraging the 628 N push force to snap light cardboard cartons into a secondary lane.
Drives an arcing tensioning arm on a textile machine, where the compact riveted aluminum body fits into tight loom framing and the fixed rubber bumper absorbs rapid cycling impacts.
Opens and closes a small gravity-fed hopper gate for plastic granules, relying on the 528 N pull force to retract the 16 mm rod against the weight of the material column.
Selecting the MBL40X65CA makes sense when your mechanism requires 628 N of push force at 0.5 MPa alongside a pivoting rear mount. If your application needs less force, stepping down to the 32 mm bore yields 402 N of push force; if you need more clamping power, the 50 mm bore provides 981 N. Keep in mind that a plain MBL does not hold its position or load when air pressure is exhausted or the valve is centered—the rod will drift or drop. If the load must be held without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
For replacement or new design, verify these exact attributes: 40 mm bore, 65 mm stroke, G1/4 port size, PT thread form, CA pivot back cover, and no built-in magnet. If your cycle speeds generate too much kinetic energy for the fixed rubber bumper to absorb, step up to the MBLC variant, which replaces the bumper with an adjustable air cushion for heavier loads. At 65 mm of stroke, side-load bending is minimal, but always ensure the CA clevis pin is aligned with the load's arc to prevent rod-bearing wear.
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. The theoretical maximum force is 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-800 mm/s.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke damping, not an adjustable cushion screw. If you need adjustable air cushioning, select the MBLC variant.
