About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50U
The AirTAC MBLC50X50U is a double-acting, 50mm bore mini cylinder engineered for compact automation. It yields 981N of push force and 881N of pull force at 0.5 MPa. The 50mm stroke is well-suited for short, powerful linear actuation in tight machinery envelopes. Unlike standard ISO 15552 bodies, this cylinder uses a riveted rolling-packed aluminum barrel, keeping weight down while maintaining structural integrity.
This U-type configuration features a rigid flat-end back cover. A defining mechanical trait is the screw-adjustable pneumatic air cushion at both stroke ends. By tuning the needle valve, you control the deceleration rate of the 16mm hard-chrome carbon-steel rod, minimizing end-cover impact and vibration on heavier loads. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50U Is Used
Pallet Diverters
Drives short 50mm redirection arms on packaging conveyor lines, using the 981N push force to slide heavy cartons while the adjustable cushion halts the mass smoothly.
Carton Lid Presses
Executes rapid 50mm tamping strokes to seal adhesive flaps on packing machines, where the tunable air cushion prevents jarring impacts during continuous high-frequency cycling.
Bearing Seating
Presses bearings into housings on automated assembly fixtures, relying on the rigid U-type flat-end back cover to maintain precise alignment during the 881N pull retraction.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50U the Right Cylinder?
At 0.5 MPa, this 50mm bore generates 981N push and 881N pull. If your payload is lighter, step down to the 40mm bore, which supplies 628N push and 528N pull. For heavier mass, step up to the 63mm bore, offering 1558N push and 1457N pull. Choose this MBLC variant over the base MBL when cycle speeds are high enough that a fixed rubber bumper would prematurely wear the end covers. For replacement, match the 50mm bore, 50mm stroke, G1/4 port, PT thread, U flat-end back cover, and confirm no magnet is required. The cylinder does not hold position upon air loss; the cushion only decelerates near the ends rather than locking the rod.
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 MBLC50X50U FAQ
This 50mm bore cylinder delivers 981N push and 881N pull at 0.5 MPa, 1374N push at 0.7 MPa, and a maximum theoretical output of 200 kgf at 1.0 MPa.
The MBLC50X50U features a screw-tunable needle valve at both ends. You adjust it to meter the exhaust air escaping near the stroke endpoints, decelerating the piston smoothly. This protects the end covers from impact damage on fast moves, functioning as a shock absorber rather than a load lock.
