About the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225-CA
The AirTAC MBL25X225-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Generating 245 N push and 206 N pull force at 0.5 MPa, this 25 mm bore, 225 mm stroke unit is tailored for mid-range arc and angular movements. The CA pivot back cover allows the body to swing on a pin, accommodating lateral motion paths that a rigid flat-end cylinder cannot.
Unlike tie-rod bodies, the MBL uses a riveted rolling-packed aluminum barrel where the covers are crimped directly to the tube, ensuring a lightweight footprint but making it a non-rebuildable assembly. Longevity is handled internally by a heterogeneous two-way piston seal that retains grease, paired with a carbon steel rod plated with 20 um of hard chrome for wear resistance. This SKU lacks the -S suffix, meaning no built-in magnet is present and CMSG/DMSG/EMSG position sensors cannot be fitted.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225-CA Is Used
Textile Loom Guide Arm
Drives an oscillating guide arm on a textile weaving loom, utilizing the 245 N push force and CA pivot cover to smoothly arc yarn threads into position without binding.
Package Diverter Flap
Actuates a pivoting diverter flap on a 400 mm wide packaging conveyor, where the 206 N pull retracts the gate to sort small cartons into secondary lanes.
PCB Component Loader
Pushes a rotating pick-and-place arm in a PCB assembly machine, using the 225 mm stroke to extend the arm deep into tight electronic component tape feeders.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL25X225-CA the Right Cylinder?
At 0.5 MPa, this 25 mm bore yields 245 N of push force. If your application requires less energy, step down to the 20 mm bore (157 N push); if moving heavier payloads, step up to the 32 mm bore (402 N push). For end-of-stroke energy absorption on faster cycles, consider the MBLC variant which features an adjustable air cushion instead of the base MBL's fixed rubber bumper. If you need fail-safe holding, note that a plain MBL will drift and drop when air pressure is lost or exhausted—the rubber bumper softens impact but acts as no lock; add an external pilot-operated check valve for position holding.
With a 225 mm stroke, the 10 mm rod is highly susceptible to bending under side loads. The CA clevis mount helps mitigate this by allowing the cylinder to articulate, but you should still ensure the load is guided externally or evaluate the MBLD double-rod type for strict anti-rotation requirements. Replacement match: 25 mm bore, 225 mm stroke, G1/8 port, PT thread, CA pivot back cover, no mounting accessory, no 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 MBL25X225-CA FAQ
This 25 mm bore cylinder features a G1/8 port and a Ø10 mm rod. At 0.5 MPa it provides 245 N push and 206 N pull force. At 0.7 MPa push increases to 343 N, with a maximum theoretical force of 50 kgf at 1.0 MPa.
No. The base MBL25X225-CA uses a fixed rubber bumper to soften end impacts, not an adjustable air cushion screw (for that, choose the MBLC variant). Additionally, because this SKU lacks the -S magnet suffix, CMSG, DMSG, or EMSG electronic position sensors cannot be installed.
