About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175SCA
The AirTAC MBLC40X175SCA is a double-acting aluminum mini cylinder with a 40 mm bore and 175 mm stroke. It delivers 628 N push and 528 N pull force at 0.5 MPa. A screw-tunable pneumatic cushion at both ends decelerates the piston smoothly near stroke limits, cutting impact and vibration on faster moves. This is not a load lock or brake, but an end-of-stroke damping system that protects the end covers.
This SKU includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches to detect rod position, and a CA pivot back cover that swings on a pin for arcing loads. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175SCA Is Used
Textile Loom Guide Arms
Drives oscillating guide arms on a weaving loom. The CA pivot absorbs the arcing load while the cushion dampens the 628 N push at high cycle rates, preventing end-cover impact on the 175 mm stroke.
Package Sorter Diverter
Actuates a pivoting diverter gate on a packaging conveyor. The adjustable needle tunes the deceleration to match the gate weight, and the -S magnet triggers a DMSG electronic sensor to confirm gate position.
PCB Component Placement
Moves a placement head over a 175 mm travel distance in electronics assembly. The compact riveted barrel fits the tight machine envelope, while the cushion ensures the 528 N pull retracts without jarring the delicate components.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X175SCA the Right Cylinder?
At 0.5 MPa, this 40 mm bore yields 628 N push and 528 N pull. If your application needs less force, the 32 mm bore neighbor provides 402 N push; if you need more, the 50 mm bore offers 981 N push. Choose this MBLC over the base MBL when your cycle speeds are high or the moved mass is heavy enough that a fixed rubber bumper cannot absorb the impact. The 175 mm stroke demands careful alignment; the CA clevis back cover accommodates angular arc movement, but for long-stroke rigid loads, consider an external guide or the MBLD double-rod type to prevent rod bending. A plain MBLC will drift if air is lost; use an external rod lock for position holding without live air.
Replacement match: 40 mm bore, 175 mm stroke, G1/4 port, PT thread, CA pivot back cover, built-in magnet (-S).

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 MBLC40X175SCA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, it provides 880 N push. The maximum theoretical force is 128 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
The screw-tunable pneumatic cushion traps air at both stroke ends to decelerate the piston smoothly, reducing impact on fast or heavy moves. The CA pivot back cover is a clevis style that swings on a pin, making it ideal for arcing or angular loads that would bind a rigid flat-end mount.
