About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175CA
The AirTAC MBLC20X175CA is a compact double-acting aluminum mini cylinder engineered for tight spaces, delivering 157 N of push force and 132 N of pull force at 0.5 MPa. A 175 mm stroke makes it highly suitable for reaching into compact machinery where a longer extension is required without occupying a large footprint. Unlike the base MBL, this variant features a screw-adjustable pneumatic air cushion at both ends, allowing you to tune the end-of-stroke deceleration to match your load and speed.
This specific SKU is configured with a CA pivot back cover that swings on a pin to accommodate arcing loads, and a PT tapered port thread. Because this model lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor. The riveted rolling-packed aluminum barrel keeps the unit lightweight, while the Ø8 mm carbon-steel rod features a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for extended service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175CA Is Used
Textile Loom Guide Arm
Actuates a yarn guide arm over a 175 mm path; the CA pivot absorbs angular motion while the tuned cushion prevents end-cover impact during high-frequency loom cycling.
Bottle Sorting Diverter
Pushes lightweight PET bottles into a sorting lane, using the 157 N push force and adjustable end-cushioning to prevent sudden jolts that could topple the containers.
Packaging Flap Folder
Folds cardboard flaps on a compact carton erector, where the 175 mm stroke reaches across the box and the cushion needle dials out bounce for precise folding.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175CA the Right Cylinder?
Select the MBLC20X175CA when your mechanism requires arcuate motion and smooth cushioning on a 175 mm stroke. If you need less reach, the neighbouring 20 mm bore with a 150 mm stroke offers a shorter footprint while retaining the 157 N push force. For higher force demands, stepping up to the 25 mm bore increases the push force to 245 N at 0.5 MPa. Because this 175 mm stroke is relatively long for an Ø8 mm rod, side-load tolerance is low; ensure you use the CA pivot bracket to prevent rod bending, or add an external guide rail. Note that the adjustable air cushion only decelerates the piston near the ends—it is not a locking brake, so the rod will drift if air pressure is lost. For exact replacement matching, verify the 20 mm bore, 175 mm stroke, G1/8 port, PT thread, and CA pivot 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC20X175CA FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet (no -S suffix), so it cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. You would need the MBLC20X175CAS variant for reed or electronic solid-state position detection.
