About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175CA
The AirTAC MBLC40X175CA is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic air cushion at both stroke ends. Generating 628 N of push force and 528 N of pull force at 0.5 MPa, it is designed for dynamic applications where a fixed rubber bumper would fail. The 175 mm stroke provides ample travel for intermediate-distance positioning tasks.
This variant features a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, a critical requirement when the rod cannot stay perfectly aligned. It uses a G1/4 port and a Ø16 carbon-steel rod with 20 µm hard-chrome plating to resist wear. The riveted rolling-packed aluminum barrel keeps the overall envelope compact while permanently sealing the pressure chamber.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175CA Is Used
Packaging Sealing Arm
Drives a 175 mm sealing arm on a vertical form-fill-seal machine, using the tunable cushion to gently decelerate the 628 N stroke and prevent pouch crushing.
Pallet Diverter Gate
Actuates a routing gate on a parcel conveyor, where the CA pivot clevis absorbs the angular side-thrust of redirecting heavy cartons.
Board Stacking Stop
Raises a 175 mm stopper finger in a PCB assembly line, relying on the adjustable needle to soften the end-of-stroke impact during high-frequency indexing.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175CA the Right Cylinder?
If 628 N of push at 0.5 MPa is excessive for your payload, step down to the Ø32 bore, which yields 402 N of push force. For heavier payloads or higher friction, step up to the Ø50 bore, providing 981 N of push. Choose this MBLC model over the base MBL when your cycle speeds are high enough that the fixed bumper cannot absorb the kinetic energy without causing end-cover damage. Remember that the adjustable cushion only decelerates the piston near the ends; it is not a brake and will not hold the load if air pressure drops. Because the 175 mm stroke applies lateral leverage on the 16 mm rod, utilize the CA pivot clevis to prevent rod binding, or add an external guide rail for linear stability. This specific SKU lacks the -S magnet option, meaning it cannot accept CMSG, DMSG, or EMSG electronic position sensors.
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 MBLC40X175CA FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod. It delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
No, this specific SKU lacks the -S suffix, meaning it has no built-in magnet and cannot accept CMSG reed or DMSG/EMSG electronic sensor switches. You would need an MBLC40X175S variant for position detection.
