About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X500SCA
The AirTAC MBLC40X500SCA is a double-acting aluminum mini cylinder with a 40mm bore and 500mm stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, extending and retracting via a Ø16 mm hard-chrome carbon-steel rod. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensor switches for precise end-of-stroke detection, while the CA pivot back cover allows the body to swing on a pin to accommodate arcing loads.
This model uses a screw-adjustable pneumatic air cushion at both ends rather than a fixed rubber bumper. Tuning the cushion needle lets you decelerate the piston smoothly near the extremes, cutting impact shock and vibration on long, fast moves. The riveted rolling-packed aluminum barrel keeps the profile compact for tight spaces, though the lengthy 500 mm travel demands external guidance to prevent rod bending, as the small 16 mm piston rod offers low side-load tolerance.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X500SCA Is Used
Textile Loom Beater
Drives the 500 mm stroke beater mechanism on a weaving loom, using the CA pivot to absorb the transverse arc while the air cushion softens the rapid 628 N reversing impacts.
Pallet Transfer Gate
Actuates a diverter gate on a packaging conveyor, relying on the DMSG electronic sensor to confirm full extension before routing heavy goods onto a secondary line.
Vertical Lift Arm
Raises a loaded tote elevator in a compact logistics sorter, where the adjustable cushion protects the end covers from the 528 N pull force dropping rapidly under gravity.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X500SCA the Right Cylinder?
Choose this 40 mm bore when you need 628 N push force at 0.5 MPa and a lengthy 500 mm stroke. If your load is lighter, step down to the 32 mm bore (402 N push), or step up to the 50 mm bore (981 N push) for heavier masses. The CA clevis mount is essential here: at 500 mm of travel, a rigidly fixed cylinder will bind under angular misalignment, whereas the pivot bracket swings freely to absorb lateral deviation.
Select the MBLC over the base MBL when your cycle speeds are high enough that a fixed rubber bumper cannot absorb the kinetic energy without causing end-cover damage. Keep in mind the adjustable air cushion only decelerates the piston near the stroke ends; it is not a load lock. If you need to hold position vertically during a power loss, add an external rod lock or pilot-operated check valve. Replacement match: 40 mm bore, 500 mm stroke, G1/4 port, M12x1.25 rod thread, PT thread form, CA back cover, with magnet.
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 MBLC40X500SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, it yields 880 N push and 739 N pull. The maximum theoretical force is 128 kgf at 1.0 MPa. It uses a G1/4 port and an M12x1.25 rod-end thread.
A screw-tunable needle at each end traps a pocket of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match the load and speed, which is critical on a 500 mm stroke where impact velocity is high. It only dampens the end-of-stroke motion; it does not lock or hold the load.
