About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75SCA
The AirTAC MBLC40X75SCA is a double-acting aluminum mini cylinder engineered for compact actuation where end-of-stroke impact control is critical. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making this 75 mm stroke variant well-suited for mid-distance transfer and positioning tasks. Unlike the base MBL series, this model utilizes a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston, actively reducing shock, noise, and vibration on faster or heavier moves.
This configuration includes a built-in magnet (-S) for compatibility with AirTAC CMSG (reed) and DMSG/EMSG (electronic) sensor switches to track rod position. The CA back cover provides a pivot/clevis mount that swings on a pin, accommodating arcing and angular loads. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the heterogeneous two-way grease-retaining piston seal and 20 µm hard-chrome plated carbon-steel rod ensure sustained friction-free operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75SCA Is Used
Angular Component Sealing
Delivers 628 N of push at 0.5 MPa to seal housings on a rotary indexing table, using the CA pivot mount to smoothly accommodate the angular motion of the tooling arm.
Pallet Diverting Arm
Provides 528 N of pull force at 0.5 MPa to retract a diverter gate on a packaging line, with the adjustable air cushion absorbing the kinetic energy of the 75 mm rapid stroke.
Bin Tilt Mechanism
Actuates a small parts bin tilt mechanism in a semi-automated assembly cell, relying on the CMSG reed sensor switch to confirm the discharge position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X75SCA the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, whereas moving up to the 50 mm bore provides 981 N for heavier payloads. Choose this MBLC variant over the fixed rubber bumper of the standard MBL when your machine cycles at high frequency or moves a substantial mass that requires tunable end-of-stroke deceleration. Remember that the adjustable air cushion only decelerates the piston near the ends; it is not a locking mechanism. If the air supply is lost or the valve centers, the rod will drift and drop, so an external rod lock or pilot-operated check valve is required for position holding. This exact replacement match uses a 40 mm bore, 75 mm stroke, G1/4 port, M12x1.25 rod thread, PT thread form, CA pivot back cover, and an integrated magnet.

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 MBLC40X75SCA FAQ
At 0.5 MPa, this double-acting 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the output increases to 880 N of push and 739 N of pull. The theoretical maximum holding force is 128 kgf at 1.0 MPa.
The MBLC40X75SCA features a screw-tunable pneumatic needle at both ends that traps a pocket of exhaust air to smoothly decelerate the piston near the stroke limits. You tune the needle to match your specific load and speed, which prevents end-cover impact on fast moves. It functions strictly as a deceleration device and does not lock or hold the load in place.
