About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X450CA
The AirTAC MBLC20X450CA is a double-acting, aluminum-barrel 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, making it suitable for moving lighter masses over long distances. Unlike the base MBL series, this variant features a screw-adjustable pneumatic air cushion at both stroke ends. You tune the needle to smoothly decelerate the piston, cutting impact shock and vibration on faster moves.
This SKU includes a CA pivot/clevis back cover that swings on a pin to accommodate arcing loads, a critical feature for a 450 mm stroke. It uses a G1/8 port and an Ø8 mm carbon-steel rod with 20 µm hard-chrome plating. The riveted rolling-packed barrel keeps the body compact. Note that this specific model lacks a built-in magnet (-S), so it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X450CA Is Used
Textile Loom Guide
Drives a 450 mm yarn guide carriage in a textile loom, using the tunable cushion to soften end-of-stroke impacts at high cycling frequencies without stressing the compact aluminum body.
Package Diverter Arm
Actuates a lightweight swing arm on a packaging conveyor, where the CA pivot absorbs arcing loads and the 157 N push force at 0.5 MPa easily redirects small cartons.
PCB Edge Trim Scanner
Moves a scanning sensor head across long PCB panels, relying on the smooth pneumatic deceleration to prevent vibration that would blur optical inspections.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X450CA the Right Cylinder?
For sizing flexibility, stepping down to a bore 20 cylinder is not an option since this is the smallest available size. Stepping up to the bore 25 variant increases your 0.5 MPa push force to 245 N if your load requires more authority. Choose this MBLC over the fixed rubber bumper of the standard MBL when your application cycles quickly or carries enough mass to warrant tunable end-of-stroke deceleration.
Because the stroke is 450 mm, the small Ø8 mm rod is highly susceptible to bending under side loads. The CA pivot back cover on this unit helps absorb angular misalignment, but you should still use an external guide rail or consider an MBLD double-rod cylinder to prevent rod deflection. Keep in mind the adjustable air cushion only decelerates the piston near the ends; it does not lock the rod or hold position if air pressure is lost.
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 MBLC20X450CA FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
The cushion is a screw-tunable needle at both ends that traps exhaust air to decelerate the piston smoothly near the stroke ends. You adjust it to match your load and speed, which protects the end covers from impact. It is strictly a deceleration device, not a load lock or brake.
