About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X225-CA
The AirTAC MBL40X225-CA is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa, making it well-suited for mid-range actuation over its 225 mm stroke. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, ensuring a lightweight, compact footprint that cannot be disassembled like a traditional tie-rod body.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder to swing freely on a pin to accommodate arcing or angular loads during movement. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion (found on the MBLC variant). Additionally, this model lacks the -S magnet suffix, meaning it cannot support a CMSG, DMSG, or EMSG position sensor switch for rod detection.

Warehouse Sortation Gate
Operating a pivoting rejection gate in a compact parcel sortation system, utilizing the 225 mm stroke to push totes cleanly into a secondary chute.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X225-CA the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push force at 0.5 MPa; conversely, stepping up to the 50 mm bore provides 981 N for heavier loads. Because this 225 mm stroke exceeds the 300 mm threshold where side-loading becomes critical on a Ø16 mm rod, you should utilize the built-in CA pivot back cover to self-align, or add an external guide rail to prevent rod-bearing bending. For applications needing end-position adjustment, consider the MBLJ variant. Note that the fixed rubber bumper is not a locking device; the cylinder will drift and drop its load if air pressure is lost or exhausted, so fit an external pilot-operated check valve if position holding is required. Replacement parts must match the 40 mm bore, 225 mm stroke, G1/4 port size, PT thread form, and CA pivot back cover.
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 MBL40X225-CA FAQ
This 40 mm bore cylinder generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, it uses a fixed rubber bumper for end-of-stroke impact absorption; if you need adjustable air cushioning for heavier moving masses, you must switch to the MBLC variant.
