About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X450SCA
The AirTAC MBLC20X450SCA is a compact, double-acting aluminum mini cylinder engineered for a 450 mm stroke. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends, allowing you to dial in the deceleration rate to protect the end covers during high-speed or frequent cycling.
This model includes a built-in magnet (-S) for compatibility with CMSG, DMSG, and EMSG sensor switches, and uses a CA pivot back cover that swings on a pin to accommodate arcing loads. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø8 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. Note that the 450 mm stroke on an 8 mm rod creates a high risk of bending under side loads; an external guide or pivot mounting is strongly recommended.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X450SCA Is Used
Textile Loom Guide
Drives a yarn guide across a 450 mm path; the CA pivot absorbs angular rod stress while the adjustable cushion prevents snapping at high traverse speeds.
Package Divert Arm
Actuates a sorting flap on a packaging conveyor where the 157 N push force is sufficient, and the cushioned ends stop the flap smoothly without loud impacts.
Pallet Tag Applicator
Extends to press labels onto passing pallets, using the -S magnet and a DMSG sensor to confirm full extension before retraction.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X450SCA the Right Cylinder?
When sizing this 20 mm bore cylinder, consider stepping down to the smaller 16 mm bore class if your load is very light, or stepping up to the 25 mm bore (which provides 245 N push at 0.5 MPa) if you need more force. Choose this MBLC cushioned model over the fixed rubber bumper of the standard MBL when your application runs at higher speeds or cycles frequently, as the tunable needle prevents harsh end-of-stroke impacts. The CA pivot back cover is essential here for arcing motion, but remember that the air cushion only decelerates the piston near the stroke ends—it does not lock the rod. If you need to hold position without continuous air pressure, you must add an external rod lock or pilot-operated check valve. The replacement match for this SKU is: 20 mm bore, 450 mm stroke, G1/8 port, PT thread, CA pivot back cover, and -S magnet.

- ✓ 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 MBLC20X450SCA FAQ
This 20 mm bore cylinder delivers 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical output of 32 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston smoothly near the stroke limits. You adjust it to match your load and speed, which reduces impact noise and end-cover wear compared to a fixed rubber bumper. It is a deceleration device, not a load lock.
