About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X160SU
The AirTAC MBLC25X160SU is a compact double-acting aluminum mini cylinder engineered to deliver 245 N of push force and 206 N of pull force at 0.5 MPa. Driven by a Ø10 mm carbon-steel rod with a 20 µm hard-chrome plating, this 160 mm stroke unit is tailored for intermediate-travel tasks that need precise end-of-stroke control. The riveted rolling-packed aluminum barrel keeps the body light and tight, avoiding the bulk of a rebuildable tie-rod construction.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the needle valve lets you decelerate the piston smoothly, cutting end-cover impact and vibration on faster moves. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for rod position detection, while the U flat-end back cover provides a rigid, flush rear mounting face.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X160SU Is Used
PCB Depaneling Router
Drives a routing blade across 160 mm to singulate printed circuit boards, using the adjustable air cushion to brake the 245 N thrust smoothly and prevent jarring that could fracture delicate traces.
Carton Flap Folder
Extends 160 mm to fold minor carton flaps on a packaging line, relying on the DMSG electronic sensor switch to confirm fold completion and the rigid U back cover for stable mounting.
Connector Insertion Press
Pushes rectangular IC connectors into sockets with 206 N of pull force, using the tuned pneumatic cushion to soft-seat the component without damaging the 10 mm rod under repetitive cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X160SU the Right Cylinder?
Select this 25 mm bore when your application requires roughly 245 N of push force at 0.5 MPa over a 160 mm travel. If you need less force, stepping down to the 20 mm bore yields 157 N of push force; if your load is heavier, stepping up to the 32 mm bore provides 402 N. Choose this MBLC over the standard MBL when your cycle speeds are high enough that a fixed rubber bumper would cause premature wear or excessive noise. The PT tapered port thread mates with standard pneumatic fittings, and the M10x1.25 rod-end thread handles the load attachment.
Because the 160 mm stroke creates a longer lever arm on the Ø10 mm rod, side-load tolerance is low; use an external guide rail to prevent rod bending and seal distortion. A plain double-acting cylinder does not hold position when air is lost or the valve centers—the rod will drift. The adjustable air cushion only decelerates the piston near the stroke ends and is not a locking brake. For drop prevention, add an external rod lock or pilot-operated check valve.
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 MBLC25X160SU FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a G1/8 port with a PT (tapered) thread form.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near stroke ends, reducing impact compared to a fixed rubber bumper. It is not a brake; the cylinder will not hold position if air pressure is lost. For position holding, you must use an external rod lock.
