About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SCA
The AirTAC MBLC32X20SCA is a compact double-acting aluminum mini cylinder engineered for short 20 mm strokes where precise end-of-stroke control is critical. It generates 402 N of push force and 346 N of pull force at 0.5 MPa. Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle allows you to smoothly decelerate the piston near stroke extremes, effectively cutting impact shock, noise, and vibration on faster or heavier moves.
This specific configuration includes a built-in magnet (-S) for mounting AirTAC CMSG, DMSG, or EMSG sensor switches to detect rod position along its travel. The CA pivot back cover allows the cylinder body to swing on a pin, making it ideal for arcing or angular loads. Built with a riveted rolling-packed aluminum barrel for a lightweight footprint and a 20 µm hard-chrome plated carbon-steel rod, it seals via a heterogeneous two-way grease-retaining piston seal for lasting friction-free operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SCA Is Used
Pick-and-Place Grippers
Drives short 20 mm jaw movements on assembly line pick-and-place robots, using the 402 N force to grip metal components while the cushion prevents end-stop shock.
Diverter Flaps
Actuates small sorting flaps on packaging conveyors where the CA pivot accommodates the arc of the mechanism and the magnet confirms flap position.
PCB Clamping Jigs
Secures delicate printed circuit boards during testing, using the tunable cushion for soft contact at the end of the 20 mm travel to avoid damaging the board.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X20SCA the Right Cylinder?
Stepping down to the 25 mm bore reduces your output to 245 N push at 0.5 MPa, whereas stepping up to the 40 mm bore increases thrust to 628 N. Select this 32 mm model when your load requires roughly 400 N of push force within a very tight 20 mm stroke. The CA clevis mount is essential if your mechanism naturally articulates, preventing rod binding. Note that while the adjustable air cushion decelerates the piston, it does not lock or hold position when air is exhausted; for dead-load holding, an external rod lock or pilot-operated check valve is required. Replacement match: 32 mm bore, 20 mm stroke, G1/8 port, PT thread, CA pivot cover, with -S magnet.

- ✓ 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 MBLC32X20SCA FAQ
At 0.5 MPa, the 32 mm bore provides 402 N push and 346 N pull. At 0.7 MPa, it delivers 563 N push. The maximum theoretical force is 82 kgf at 1.0 MPa. It features a Ø12 mm rod, M10x1.25 rod thread, and a G1/8 port.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly before impact, which is superior to a fixed bumper for high cycle rates. Because this model includes the -S magnet, it supports AirTAC CMSG (reed) and DMSG/EMSG (electronic) sensor switches for position detection.
