About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200SU
The AirTAC MBLC40X200SU is a double-acting aluminum mini cylinder delivering 628 N of push force and 528 N of pull force at 0.5 MPa. A 200 mm stroke suits mid-range linear positioning tasks that need smooth, controlled deceleration rather than a sudden jolt. The defining feature over the base MBL is a screw-adjustable pneumatic cushion at both ends, which you tune to match your load and speed, protecting the end covers on high-frequency or heavier moves.
This SKU includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches, allowing precise end-of-stroke detection. The U suffix denotes a rigid flat-end back cover for direct mounting. It features a riveted rolling-packed aluminum barrel for a compact, light profile, paired with a Ø16 mm carbon-steel rod plated with 20 µm hard chrome to resist wear. The heterogeneous two-way grease-retaining piston seal maintains lubrication over long service intervals.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200SU Is Used
PCB Router Z-Axis
Lifts and lowers a high-speed spindle on a printed circuit board depaneling machine. The 628 N force handles the spindle mass, while the tuned air cushion prevents mechanical shock from degrading spindle bearings at the 200 mm stroke end.
Package Flap Folder
Drives a mechanical arm that tucks carton flaps on a packaging line. The adjustable cushion allows smooth deceleration of the 200 mm move despite varying cardboard thicknesses, keeping the riveted aluminum body intact during rapid cycling.
Test Fixture Gate
Actuates a sliding safety guard on an electronics functional test station. The integrated magnet works with a DMSG solid-state sensor to confirm the gate is closed, while the cushion ensures the guard closes softly without slamming.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X200SU the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) lacks the thrust for your payload, but you want to avoid stepping up to a 50 mm bore (981 N push) that demands more air volume. Select the MBLC over the fixed-bumper MBL when your 200 mm move runs at high speeds or cycles frequently, as the tunable needle prevents end-cover impact that would quickly degrade a rubber bumper. The G1/4 port and M12x1.25 rod thread are standard for this bore.
Because this model has a 200 mm stroke, side-load tolerance is a concern due to the 16 mm rod. For arcing or offset loads, consider switching to a CA pivot back cover or an SDB pivot bracket to prevent rod binding. A plain double-acting cylinder does not hold position when air is lost or the valve centers; the air cushion only decelerates near the ends and acts as no brake. For dead-stop holding without live air, specify an external rod lock.
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 MBLC40X200SU FAQ
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, push increases to 880 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod with an M12x1.25 thread, and operates at speeds of 30-800 mm/s.
The MBLC40X200SU features a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston before it hits the end cover. You adjust the needle to match your specific load and velocity, reducing impact noise and vibration on fast moves. It is strictly an end-of-stroke deceleration device, not a mid-stroke brake or load lock.
