About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X40CA
The AirTAC MBLC50X40CA is a double-acting aluminum mini cylinder engineered with a 50 mm bore and 40 mm stroke, delivering 981 N of push force at 0.5 MPa. It features a screw-adjustable pneumatic air cushion at both ends, allowing you to tune the end-of-stroke deceleration to smoothly brake heavier loads without slamming the end covers. The CA pivot clevis back cover swings on a pin to accommodate arcing or angular movements, making it superior to rigid flat mounts for dynamic linkages.
This model incorporates a riveted rolling-packed aluminum barrel for a compact, lightweight profile that fits tight machine spaces, paired with a 20 µm hard-chrome plated carbon-steel rod to resist corrosion and wear. A heterogeneous two-way grease-retaining piston seal maintains optimal lubrication over high-speed cycles. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors without modification.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X40CA Is Used
Package Diverter Arm
Drives a swinging diverter gate on a high-speed logistics conveyor, utilizing the CA pivot clevis to manage the angular load while cushioning the 981 N push force at the stroke end.
Press Brake Tooling
Actuates a short-stroke clamping mechanism on a metal press brake, where the 40 mm travel and tunable air cushion prevent shock loads from damaging the die alignment.
Seed Hopper Gate
Opens and closes a discharge gate on an agricultural seed hopper, relying on the 50 mm bore's 881 N pull force to overcome sticky material resistance and the cushion to soften closure.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X40CA the Right Cylinder?
Select this 50 mm bore when an application requires substantial thrust—981 N push and 881 N pull at 0.5 MPa—over a short 40 mm travel. If you need less force, step down to the 40 mm bore, which provides 628 N push at 0.5 MPa. For heavier loads requiring more power, the 63 mm bore offers 1558 N push at 0.5 MPa. The adjustable air cushion is essential here if you are cycling quickly or moving a high mass where a fixed rubber bumper would degrade or fail. Keep in mind that a plain double-acting cylinder does not hold position if air pressure drops or the valve centers; the rod will drift. For dead-stop holding without live air, add an external rod lock or pilot-operated check valve. Replacement parts require matching the 50 mm bore, 40 mm stroke, G1/4 port, PT thread, CA pivot back cover, and no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X40CA FAQ
The 50 mm bore generates 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical 200 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and an M14x1.5 rod-end thread.
This specific SKU lacks the -S code, so it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensors. The adjustable air cushion at both ends uses a screw needle to restrict exhaust flow, decelerating the piston smoothly near the ends to reduce impact and noise; it is a braking mechanism, not a lock.
