About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100SCA
The AirTAC MBL25X100SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It provides 245 N of push force and 206 N of pull force at 0.5 MPa, making it well-suited for 100 mm stroke actuation in small part handling. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, ensuring a lightweight footprint that is not designed to be disassembled like a tie-rod cylinder.
This specific SKU features a built-in magnet (-S) for position sensing with AirTAC CMSG (reed) or DMSG and EMSG (solid-state) switches. It also includes a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. The Ø10 mm piston rod is carbon steel with 20 µm hard-chrome plating for wear resistance, and it relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100SCA Is Used
Textile Loom Yarn Guide
Drives a 100 mm arcing motion for a yarn guide carriage on a textile loom, using the CA pivot to absorb angular side loads while applying 245 N of push force at 0.5 MPa.
PCB Tray Divertor
Pushes empty PCB trays out of a testing station on a tight 25 mm bore footprint, where the built-in magnet triggers a DMSG solid-state switch to confirm ejection.
Small Parts Sorting Gate
Actuates a 100 mm swing gate to sort small plastic fasteners into packaging chutes, utilizing the lightweight riveted aluminum body to fit within a dense conveyor framework.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X100SCA the Right Cylinder?
If you need less force, step down to the Ø20 bore, which offers 157 N push at 0.5 MPa. For heavier lifting, step up to the Ø32 bore, which provides 402 N push at 0.5 MPa. Choose the MBLC variant if your application requires adjustable air cushioning to dissipate kinetic energy at higher speeds. Since this is a 100 mm stroke, side-load tolerance on the Ø10 mm rod is moderate; ensure an external guide or the CA pivot is used to prevent rod-bearing bending.
A standard MBL does not hold its position or load when air pressure is lost or the valve is centred—the rod drifts or drops. The rubber bumper only softens end-of-stroke impact and is not a lock or brake. If the load must be held without live pressure, install an external rod lock or a pilot-operated check valve. For replacement, match the 25 mm bore, 100 mm stroke, G1/8 port, PT thread, CA back cover, and -S 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 MBL Aluminum Alloy Mini Cylinder MBL25X100SCA FAQ
At 0.5 MPa, the Ø25 bore provides 245 N push and 206 N pull force. At 0.7 MPa, the push force is 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If you need adjustable air cushioning for heavier moving loads, select the MBLC variant.
