About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X350SCA
The AirTAC MBLC40X350SCA is a double-acting aluminum mini cylinder engineered for compact spaces requiring a 350 mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a G1/4 port and a Ø16 hard-chrome carbon-steel rod with an M12x1.25 end thread. The CA pivot back cover allows the body to swing on a pin, accommodating arcing loads, while the built-in magnet (-S) enables position detection.
This model features a screw-adjustable pneumatic air cushion at both ends, allowing you to tune end-of-stroke deceleration for heavier or faster moving loads to reduce impact and vibration. The riveted rolling-packed aluminum barrel keeps the unit light, and the heterogeneous two-way grease-retaining piston seal ensures lasting lubrication. Because the stroke is 350 mm, the 16 mm rod has limited tolerance for side loads, making the CA clevis ideal for preventing rod binding during travel.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X350SCA Is Used
Textile Loom Beat-Up
Drives the 350 mm stroke beating motion on weaving looms, using the CA pivot to absorb angular stress and the adjustable cushion to silently decelerate the 628 N push force.
Pallet Transfer Deflector
Extends to divert heavy cardboard pallets on a packaging line, relying on the tunable air cushion to prevent end-cover damage during high-frequency 0.7 MPa operations.
Warehouse Vertical Gate
Raises and lowers a compact access gate where the 350 mm stroke requires smooth end-of-stroke braking, detected by a DMSG electronic sensor switch.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X350SCA the Right Cylinder?
If you need less force, the neighbouring bore down is 32 mm (providing 402 N push at 0.5 MPa), or you can step up to the 50 mm bore for 981 N push at 0.5 MPa. Choose this MBLC variant over the base MBL when your cycle speeds are high enough that a fixed rubber bumper cannot adequately absorb the kinetic energy. For exact replacements, match the 40 mm bore, 350 mm stroke, G1/4 port, PT thread, CA pivot back cover, and the -S magnet. Note that the air cushion only decelerates the piston near the ends; it does not hold position if air pressure is lost.
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 MBLC40X350SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull. At 0.7 MPa, it yields 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa operating pressure.
The cushion needle is screw-tunable at both ends to restrict exhaust flow, decelerating the piston smoothly before it hits the end cover. This protects the cylinder on fast or heavy 350 mm moves and is superior to a fixed rubber bumper, though it does not lock the rod in place.
