About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X15SCA
The AirTAC MBLC25X15SCA is a compact double-acting aluminum mini cylinder engineered for very short 15 mm strokes. It delivers 245 N of push force and 206 N of pull force at 0.5 MPa. The riveted rolling-packed aluminum barrel keeps the body light and tight for cramped machine layouts, while the 20 µm hard-chrome plating on the carbon-steel rod defends against wear. Inside, a heterogeneous two-way grease-retaining piston seal maintains lubrication for millions of cycles.
This SKU features a built-in magnet (-S) for compatibility with CMSG reed and DMSG or EMSG electronic sensor switches to track rod position. The CA back cover provides a pivot clevis that swings on a pin to absorb angular misalignment. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC model incorporates a screw-adjustable pneumatic air cushion at both ends to smoothly decelerate the piston, reducing end-cover impact and vibration on rapid strokes.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X15SCA Is Used
PCB Router Pin Extraction
Uses the 245 N push force and 15 mm stroke to rapidly eject small machined pins from a router fixture. The adjustable air cushion prevents end-cap chatter during high-frequency 30-800 mm/s cycling.
Packaging Flap Tucking
Tucks carton flaps on a continuous motion packaging line. The CA pivot cover accommodates the arcing motion as the box travels past, while the short stroke fits within the narrow folder frame.
Connector Insertion Press
Presses electronic ribbon connectors onto headers with a delicate 206 N pull force. The built-in magnet works with a DMSG solid-state sensor to verify the exact 15 mm insertion depth.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X15SCA the Right Cylinder?
For sizing, if 245 N of push force at 0.5 MPa is insufficient, step up to the 32 mm bore which yields 402 N. Conversely, if you are over-moving a light payload, step down to the 20 mm bore providing 157 N. The 15 mm stroke is ideal for micro-clamping, but if the application requires holding position without continuous air pressure, note that the adjustable cushion only decelerates the stroke near the ends and does not lock the rod; an external pilot-operated check valve or rod lock is required for true drop prevention.
This specific configuration uses a CA pivot back cover with a default PT tapered port thread. The replacement match is bore 25, stroke 15, port PT, rod-end thread M10x1.25, CA back cover, and an internal magnet for sensor switching. Because the stroke is only 15 mm, side-load stress is minimal, but the CA clevis remains highly beneficial for absorbing angular rod deflection during fast pivot motions.
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 MBLC25X15SCA FAQ
The 25 mm bore generates 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum theoretical 50 kgf at 1.0 MPa. It uses a G1/8 port with a default PT tapered thread, and the rod end is M10x1.25.
The adjustable air cushion at both ends uses a screw needle to tune end-of-stroke deceleration, preventing harsh impacts on fast moves where a fixed rubber bumper would fail. The CA back cover acts as a pivot clevis, swinging on a pin to accommodate arcing loads and angular misalignment.
