About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15SU
The AirTAC MBLC50X15SU is a compact double-acting aluminum mini cylinder engineered for short, high-force linear motion. It delivers a robust 981 N push and 881 N pull force at 0.5 MPa, making it well-suited for tight-space clamping or pressing operations requiring a brief 15 mm stroke. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke limits, reducing impact stress on the flat U back cover during rapid cycles.
This model incorporates a built-in magnet (indicated by the S code) for non-contact position detection using CMSG reed or DMSG and EMSG solid-state sensor switches. The riveted rolling-packed aluminum barrel keeps the body lightweight yet durable, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear. The heterogeneous two-way grease-retaining piston seal ensures consistent lubrication, maintaining smooth mechanical operation across the 30-800 mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15SU Is Used
PCB Edge Clamping
Uses the 981 N push force at 0.5 MPa to secure circuit boards during wave soldering, with the 15 mm stroke providing rapid engagement in confined assembly machinery.
Package Flap Folding
Actuates cardboard folding mechanisms on packaging lines where the short 15 mm travel quickly tucks flaps, relying on the adjustable air cushion to prevent hard slamming at high cycle rates.
Connector Insertion Press
Presses electronic headers into sockets with precise 15 mm travel, utilizing the DMSG electronic sensor switch to verify the exact insertion depth before signaling the controller.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X15SU the Right Cylinder?
For applications needing less force, stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa, whereas scaling up to the 63 mm bore provides 1558 N for heavier loads. The MBLC is preferred over the standard MBL when moving substantial mass quickly, as the fixed rubber bumper of the MBL cannot adequately absorb the kinetic energy that this 50 mm bore generates at high speeds. Remember that the adjustable air cushion only decelerates the piston near the end of travel; it is not a brake and will not hold the rod in place if air pressure is lost.
This replacement match features a 50 mm bore, 15 mm stroke, G1/4 port, PT thread form, U flat-end back cover, and a built-in magnet for sensor tracking. Because the stroke is only 15 mm, side-load stress on the rod is minimal, though the small 16 mm rod diameter still means external guides are recommended if the load is offset or heavily unbalanced.
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 MBLC50X15SU FAQ
This cylinder has a 50 mm bore, a G1/4 port, and a Ø16 mm rod with an M14x1.5 rod-end thread. The theoretical force output is 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum of 200 kgf at 1.0 MPa.
The MBLC50X15SU features a screw-tunable needle valve at both ends that traps a pocket of exhaust air to decelerate the piston before it hits the end cover. You tune the needle to match your specific load and speed, which is critical for a 50 mm bore cylinder moving heavy masses, as it absorbs kinetic energy far better than a fixed rubber bumper.
