About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30SCA
The AirTAC MBLC40X30SCA is a compact double-acting aluminum mini cylinder engineered for short, rapid 30 mm strokes. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle lets you decelerate the piston smoothly near stroke extremes, absorbing kinetic energy to cut impact shock, noise, and vibration on fast moves.
This SKU includes a built-in magnet (S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to detect rod position. It uses a CA pivot back cover that swings on a pin, making it ideal for arcing or angular loads. The riveted rolling-packed aluminum barrel keeps the body light and compact for tight machinery, while the Ø16 mm carbon-steel rod features 20 µm hard-chrome plating and a heterogeneous two-way grease-retaining piston seal for low-friction longevity.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30SCA Is Used
Pick-and-Place Ejector
Uses the 628 N thrust and 30 mm travel to rapidly eject stamped metal components from a press die, relying on the tuned air cushion to soften the abrupt end-of-stroke impact.
Pivot Arm Diverter
Leverages the CA clevis back cover to swing a diverter gate on a packaging line, handling angular motion while the compact riveted barrel fits within tight guard clearances.
PCB Test Station
Drives a testing probe 30 mm downward into circuit boards, using the S magnet with a DMSG electronic sensor to confirm exact engagement position without rebound bounce.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X30SCA the Right Cylinder?
Choose this 40 mm bore when you need 628 N of thrust at 0.5 MPa for a brief 30 mm stroke. If your application requires less force, stepping down to the 32 mm bore yields 402 N of push force. If you need to move heavier loads, stepping up to the 50 mm bore provides 981 N. The CA pivot clevis is specified here to accommodate arcing loads, which is critical because the 16 mm rod has low side-load tolerance. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a brake. A plain MBLC does not hold position if air is lost or the valve centers, so use an external rod lock for fail-safe holding.
This exact replacement matches: 40 mm bore, 30 mm stroke, G1/4 port, PT thread, CA pivot back cover, and S magnet. The CMSG reed switch or DMSG/EMSG electronic sensors mount directly to the body for position feedback.

- ✓ 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 MBLC40X30SCA FAQ
This 40 mm bore cylinder uses a G1/4 port and a Ø16 mm rod. At 0.5 MPa it provides 628 N push and 528 N pull force. At 0.7 MPa it provides 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your load and speed, which reduces impact wear and noise. It functions only for end-of-stroke deceleration and does not lock or hold the rod in place.
