About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225SCA
The AirTAC MBLC40X225SCA is a compact double-acting aluminum mini cylinder featuring a tunable pneumatic cushion at both stroke ends. Delivering 628 N of push force at 0.5 MPa, this 225 mm stroke unit is built for fast moves where the fixed rubber bumper of the standard MBL would fail. The riveted rolling-packed aluminum barrel keeps the body light and tight for machine spacing constraints.
This SKU includes a CA pivot back cover that swings on a pin to absorb arcing angular loads, alongside a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches. The Ø16 mm carbon-steel rod is protected by 20 µm hard-chrome plating, while the heterogeneous two-way grease-retaining piston seal ensures lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225SCA Is Used
Pivot Arm Actuation
Drives a swinging pick-and-place arm in PCB handling, using the CA clevis to absorb arcing loads while the cushion halts the 225 mm swing smoothly.
Divert Gate Control
Positions a routing flap on a packaging conveyor, relying on the 628 N push force and tunable end-covers to survive high-frequency shifts.
Test Socket Clamping
Secures semiconductor sockets during automated testing, using the -S magnet and DMSG electronic switch to confirm clamp position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225SCA the Right Cylinder?
Step down to the 32 mm bore if your load requires only 402 N of push force at 0.5 MPa, or step up to the 50 mm bore for 981 N when moving heavier fixtures. Choose this MBLC variant over the base MBL when cycling rapidly with a substantial payload, as the screw-adjustable needle decelerates the piston smoothly to protect the end covers. Note that this air cushion only decelerates near the ends; it is not a lock, so the rod will drift if air is lost.
At 225 mm of travel, the small 8-16 mm rod family has limited side-load tolerance. The CA clevis back cover on this unit helps by pivoting on a pin, but for rigid straight-line pushes you should add an external guide rail or consider an MBLD double-rod cylinder. Replacement match: 40 mm bore, 225 mm stroke, G1/4 port, PT thread, CA pivot back cover, no mounting bracket, with 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC40X225SCA FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa.
A screw-tunable needle traps exhaust air at both stroke ends to decelerate the piston smoothly. You tune it to match your load and speed, which cuts impact noise and end-cover wear compared to a fixed rubber bumper. It is strictly an end-of-stroke damper, not a braking lock.
