About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X400SCA
The AirTAC MBLC50X400SCA is a double-acting aluminum mini cylinder featuring a 50mm bore and 400mm stroke. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa. A built-in magnet (-S) enables position detection using CMSG reed or DMSG and EMSG electronic sensor switches. The CA back cover provides a pivot clevis that swings on a pin, accommodating arcing or angular loads during motion.
This model uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, which is critical for protecting the end covers on long, fast moves. It features a riveted rolling-packed aluminum barrel for a compact, lightweight profile and a 20 um hard-chrome plated carbon-steel rod with a heterogeneous two-way grease-retaining piston seal for extended service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X400SCA Is Used
Textile Loom Let-off
Drives the tensioning beam on a weaving loom, using the 981 N push force and CA pivot to accommodate fabric roll angularity across the 400mm stroke.
Pallet Transfer Gate
Actuates a diverter gate on a packaging conveyor, relying on the adjustable air cushion to softly stop the 400mm extension without shocking the pivot bracket.
Warehouse Vertical Lift
Raises tote boxes in an automated storage system, using the -S magnet and DMSG electronic switch to confirm the fully raised position at 400mm.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X400SCA the Right Cylinder?
For 0.5 MPa output, step down to the 32mm bore (402 N push) for lighter tasks, or step up to the 63mm bore (1558 N push) for heavier loads. Choose this MBLC cushioned version over the base MBL when cycling speeds are high and a fixed rubber bumper cannot absorb the kinetic energy. The cushion needle tunes deceleration but does not lock the rod; a plain cylinder drifts when air is lost, so add an external rod lock for fail-safe holding. Replacement match: 50mm bore, 400mm stroke, G1/4 port, PT thread, CA pivot cover, magnet fitted. At 400mm stroke, side-load and rod bending risks are high; guide the load externally, use the CA pivot, or select an MBLD double-rod cylinder to prevent binding.
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 MBLC50X400SCA FAQ
At 0.5 MPa, this 50mm bore cylinder provides 981 N push and 881 N pull. At 0.7 MPa, it delivers 1374 N push. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends restricts exhaust air to decelerate the piston near the stroke limits. You set the restriction to match the load and speed, cutting end-cover impact and vibration. It only decelerates near the ends and is not a brake or load lock.
