The AirTAC AirTAC MBL50X40CA Mini Cylinder | 50mm Bore 40mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 40mm 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 MBL50X40CA is a compact double-acting aluminum mini round cylinder engineered to deliver 981 N of push force and 881 N of pull force at 0.5 MPa. Driven by a Ø16 mm carbon-steel rod with 20 μm hard-chrome plating, this 40 mm stroke unit is built for tight machine envelopes where a larger profile cylinder will not fit. The riveted rolling-packed barrel keeps the overall body exceptionally light, though it is not designed to be disassembled or rebuilt in the field like a traditional tie-rod cylinder.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. It relies on a heterogeneous two-way piston seal that retains grease for extended cycle life. Because this configuration lacks the -S suffix, it has no internal magnet and cannot accept a CMSG, DMSG, or EMSG position sensor. The end-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion screw.

Pivots a thread guide arm along a 40 mm arc in narrow weaving looms, utilizing the CA clevis to absorb lateral deflection while applying 981 N of push force at 0.5 MPa.
Folds heavy cardboard carton flaps in a compact packaging line where the 881 N pull stroke retracts the arm, fitting into tight side-frame spaces where ISO cylinders cannot.
Maintains dynamic tension on a conveyor belt assembly by swinging a pivot bracket, relying on the riveted aluminum body for low-weight operation and the fixed bumper to absorb shock.
At 0.5 MPa, this 50 mm bore generates 981 N of push force. If your assembly requires less force, stepping down to the 40 mm bore yields 628 N push, while moving up to the 63 mm bore provides 1558 N for heavier payloads. If your cycle speed demands end-of-stroke deceleration for a heavy mass, step across to the MBLC variant for its adjustable air cushion. For applications needing push-only or pull-only action, consider the MSBL or MTBL single-acting lines.
The CA pivot back cover is ideal for picking and placing parts along a curved path. Remember that the fixed rubber bumper only softens end-stop impact; it does not hold the load. If air pressure drops or the valve is centered, the rod will drift and drop. Use an external rod lock or pilot-operated check valve if the payload must be held without live pressure. For replacement, match the 50 mm bore, 40 mm stroke, G1/4 port size, PT thread form, CA pivot cover, and no magnet.
Quick checklist
The 50 mm bore operates on a G1/4 port with a Ø16 mm rod. At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa the push force reaches 1374 N, and the maximum theoretical force is 200 kgf at 1.0 MPa.
No. This SKU lacks the -S suffix, meaning it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning, you must specify the MBLC variant.
