About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250SU
The AirTAC MBLC50X250SU is a double-acting aluminum mini cylinder engineered for compact setups demanding high force and smooth deceleration. It pushes with 981 N and pulls with 881 N at 0.5 MPa, making this 250 mm stroke variant well suited for moving heavier jigs or lifting mid-weight assemblies. Unlike the base MBL, this MBLC body incorporates a screw-adjustable pneumatic cushion at both stroke ends, allowing you to fine-tune the end-of-stroke deceleration and eliminate harsh cover impacts on faster cycles.
This SKU features a built-in magnet (S) for position detection via AirTAC CMSG, DMSG, or EMSG sensor switches, and a rigid flat-end U back cover. The riveted rolling-packed aluminum barrel keeps the envelope tight, while the Ø16 carbon-steel rod is protected by a 20 µm hard-chrome plating. A heterogeneous two-way grease-retaining piston seal ensures consistent lubrication across the 30-800 mm/s operating speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250SU Is Used
Pallet Diverter Arm
Actuates a routing flap on a packaging conveyor, using the 981 N push force to swiftly redirect heavy cardboard cartons while the adjustable cushion prevents end-cap shock on the 250 mm extension.
CNC Lathe Bar Feeder
Advances raw steel stock into a collet chuck, relying on the -S magnet and a DMSG electronic sensor to confirm the fully retracted position before the spindle starts.
Vertical Lift Gate
Raises a 20 kg tooling tray on a testing machine, utilizing the 881 N pull force at 0.5 MPa to lower the load smoothly without slamming, thanks to the screw-tunable pneumatic cushion.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250SU the Right Cylinder?
Select this 50 mm bore when your application requires approximately 981 N of push force at 0.5 MPa. If you need less force, step down to the 32 mm bore which provides 402 N push; if you require more power, step up to the 63 mm bore delivering 1558 N push. The adjustable air cushion is specifically beneficial here over the fixed rubber bumper of the standard MBL, as a 250 mm stroke builds significant piston momentum that a fixed bumper cannot adequately absorb.
Because this 250 mm stroke generates leverage, the Ø16 rod has limited tolerance for side-load and may deflect under off-center loading. To manage rod bending, use an external guide rail, select a CA or SDB pivot mounting to accommodate arcing loads, or switch to an MBLD double-rod cylinder. Note that the pneumatic cushion only decelerates the piston near the ends and does not lock the rod; if you need to hold position without live air, install an external rod lock or pilot-operated check valve. This configuration includes a G1/4 port, PT thread form, and a U flat-end cover.
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 MBLC50X250SU FAQ
This 50 mm bore cylinder uses a G1/4 port and a Ø16 rod with an M14x1.5 thread. At 0.5 MPa it pushes with 981 N and pulls with 881 N. At 0.7 MPa, push increases to 1374 N and pull to 1233 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps a small amount of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your load and speed, which is critical for a 250 mm stroke. It only slows the rod near the stroke ends and does not function as a brake or load lock.
