About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20U
The AirTAC MBLC32X20U is a compact double-acting aluminum mini cylinder engineered for short 20 mm strokes. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the end-of-stroke deceleration to protect the end covers on rapid cycles.
This specific SKU uses a rigid U flat-end back cover and a PT tapered port thread. Because it lacks the -S suffix, it is built without a magnet and cannot accept a CMSG, DMSG, or EMSG position sensor. The Ø12 mm carbon-steel rod features 20 um hard-chrome plating, and the heterogeneous two-way grease-retaining piston seal ensures consistent friction throughout its 30-800 mm/s operating speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20U Is Used
PCB Edge-Guiding Gate
Snaps a 20 mm stroke to shift delicate printed circuit boards laterally between conveyor lanes, using the adjustable cushion to prevent bounce on retraction.
Packaging Flap Tucker
Deploys a short 402 N push at 0.5 MPa to fold carton flaps prior to sealing, benefiting from the tunable air cushion to avoid crushing the cardboard.
Connector Insertion Press
Drives a small electronic header into a socket with a controlled 20 mm advance, relying on the end-cushions to absorb shock at high cycle rates.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20U the Right Cylinder?
For a 32 mm bore, this 20 mm stroke is ideal for very short, high-speed ejection or clamping moves where the 402 N force at 0.5 MPa is sufficient. If you need less force, stepping down to the 25 mm bore yields 245 N of push force. If your application requires more power, stepping up to the 40 mm bore provides 628 N. Choose this MBLC cushioned version over the fixed-bumper MBL when cycling rapidly with heavier loads, as the needle valve bleeds trapped air to prevent harsh end-cover impacts. Note that the cushion only decelerates the piston near the stroke ends; it does not lock the rod or hold position if air pressure is lost.
Replacement match: 32 mm bore, 20 mm stroke, G1/8 port with PT thread, U flat-end back cover, no magnet. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight machine spaces.
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 MBLC32X20U FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, push increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. It uses a Ø12 mm rod with an M10x1.25 rod-end thread and a G1/8 port.
No, this specific SKU is manufactured without a built-in magnet, so it cannot trigger AirTAC CMSG, DMSG, or EMSG sensor switches. If you require position detection, you must select the MBLC32X20S variant which includes the magnetic piston.
