About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125SCA
The AirTAC MBLC32X125SCA is a double-acting aluminum mini cylinder with a 32 mm bore and 125 mm stroke. It produces 402 N of push force and 346 N of pull force at 0.5 MPa. The built-in magnet (-S) enables position detection using CMSG reed or DMSG and EMSG electronic sensor switches. A CA pivot back cover allows the body to swing on a pin, accommodating arcing or angular motion paths.
This model uses a screw-adjustable pneumatic air cushion at both stroke ends to decelerate the piston smoothly, which is critical for protecting the end covers during faster or heavier moves. It features a riveted rolling-packed aluminum barrel for a compact footprint in tight spaces. The 20 µm hard-chrome plated carbon-steel rod works alongside a heterogeneous two-way grease-retaining piston seal to maintain lubrication over long service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125SCA Is Used
PCB Router Swing Arm
Drives a pivoting routing head along an arc. The CA clevis accommodates the swing path while the cushion absorbs the 125 mm stroke impact at high traversal speeds.
Bottle Diverter Gate
Actuates a routing flap on a packaging line. The adjustable cushion prevents the 346 N pull force from slamming the gate shut, protecting the end covers.
Component Test Fixture
Applies 402 N of clamping force to electronic modules. The -S magnet allows a DMSG sensor to verify clamp position before testing begins.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X125SCA the Right Cylinder?
At 0.5 MPa, this 32 mm bore generates 402 N push and 346 N pull. If your application requires less force, the 25 mm bore offers 245 N push, stepping down the physical size. If you need to move heavier masses, the 40 mm bore provides 628 N push. Choose this MBLC cushioned version over the fixed rubber bumper of the base MBL when your cycle speeds are high or the moved mass is heavy enough to cause impact wear. The pneumatic cushion needle is screw-tunable to match your specific load and velocity, but it only decelerates near the ends and does not lock the rod. If you need to hold position without live air, install an external rod lock or pilot-operated check valve. The PT tapered port threads directly into standard pneumatic fittings.
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 MBLC32X125SCA FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It uses a G1/8 port, a Ø12 mm rod with an M10x1.25 rod-end thread, and PT tapered port threads.
A screw-tunable needle at both stroke ends traps exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your load and speed, which cuts impact noise and vibration. This cushion only decelerates near the ends and is not a brake or load lock.
