About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15U
The AirTAC MBLC50X15U is a double-acting aluminum mini cylinder engineered for exceptionally short, high-force strokes. It generates 981 N of push and 881 N of pull force at 0.5 MPa, driven by a Ø16 mm carbon-steel rod with a 20 µm hard-chrome plating that resists scoring. Because this SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.
Instead of a fixed rubber bumper, this body features a screw-adjustable pneumatic air cushion at both ends. You tune the needle to smoothly decelerate the piston near the 15 mm stroke limits, absorbing the kinetic energy of fast, heavy masses to prevent end-cover damage. The riveted rolling-packed aluminum barrel keeps the overall envelope compact and lightweight, making it ideal for tight machinery spaces where a tie-rod cylinder would be too bulky.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15U Is Used
Pallet Transfer Stopper
Acts as a rigid stop for 50 kg pallets on a conveyor, using its 981 N push force to arrest momentum while the tuned air cushion absorbs the impact at the 15 mm stroke end.
Press Fit Bushing
Drives small bushings into housings on an automated press line, using the short 15 mm stroke and 881 N pull to seat components rapidly without over-traveling.
Carton Flap Folder
Folds heavy cardboard flaps on a packaging line, where the high cycle rate and 981 N force require the adjustable air cushion to prevent end-cap wear over millions of actuations.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15U the Right Cylinder?
This 50 mm bore provides 981 N push at 0.5 MPa. If your payload is lighter, step down to the 40 mm bore (628 N push), or if you need more force, step up to the 63 mm bore (1558 N push). Choose this MBLC variant over the base MBL when your application cycles rapidly or carries enough mass to overwhelm a standard rubber bumper. Note that the adjustable cushion only decelerates the piston near the ends; it does not lock the rod. If you need to hold position without live air, use an external rod lock. Replacement match: 50 mm bore, 15 mm stroke, G1/4 port, PT thread, U flat-end back cover, no magnet.
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 MBLC50X15U FAQ
The MBLC50X15U has a 50 mm bore and uses a G1/4 port with an M14x1.5 rod-end thread. It delivers 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa.
No. This specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. You must select an MBLC50X15S variant if you require electronic or reed switch position feedback.
