About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175SU
The AirTAC MBLC25X175SU is a double-acting aluminum mini cylinder engineered for compact actuation, delivering 245 N of push force and 206 N of pull force at 0.5 MPa. Driven by a Ø10 mm carbon-steel rod with 20 µm hard-chrome plating, this 175 mm stroke unit is built for fast, repetitive linear motion. The U suffix denotes a rigid flat-end back cover, anchoring the rear body solidly against hard stops.
Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends. This allows you to tune the end-of-stroke deceleration to match the moving mass and velocity, absorbing kinetic energy to protect the end covers rather than relying on a fixed rubber bumper. The riveted rolling-packed aluminum barrel keeps the envelope tight and lightweight, while the integrated magnet (-S) enables position detection via CMSG reed or DMSG/EMSG solid-state switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175SU Is Used
PCB Shuttle Routing
Moves populated PCB panels between SMT inspection lanes using 245 N push force, where the tuned air cushion prevents sudden jarring that could dislodge fine-pitch components at 175 mm stroke end.
Bottle Diverter Arm
Actuates a lightweight deflector flap on a packaging conveyor, relying on the adjustable cushion to silently absorb the 175 mm travel inertia without bouncing glass bottles.
Pick-and-Place Y-Axis
Provides horizontal Y-axis displacement for small electronic part placement, using the integrated magnet to trigger DMSG solid-state sensors for precise end-position signaling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X175SU the Right Cylinder?
If your application requires less force, stepping down to the 20 mm bore yields 157 N of push force at 0.5 MPa, whereas moving up to the 32 mm bore provides 402 N. The adjustable air cushion is the primary reason to select this MBLC over the standard MBL, specifically when cycle speeds are high enough that a fixed bumper would fail prematurely. Keep in mind that the air cushion only decelerates the piston near the stroke ends; it is not a locking mechanism. If the air supply is lost or the valve centers, the rod will drift and drop, requiring an external rod lock for position holding. This 175 mm stroke uses a G1/8 port and M10x1.25 rod thread, with a standard PT tapered port thread.
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 MBLC25X175SU FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull force. At 0.7 MPa, it provides 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa operating pressure.
The cushion is a screw-tunable pneumatic needle at both ends that decelerates the piston near stroke limits to prevent hard impacts; it is not a load brake. The -S suffix means a magnet is built into the piston, allowing external CMSG reed or DMSG/EMSG electronic switches to detect rod position.
