About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X20CA
The AirTAC MBLC40X20CA is a double-acting aluminum mini cylinder engineered for a brief 20 mm stroke. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a G1/4 port and a Ø16 mm carbon-steel rod with a 20 µm hard-chrome plating. This SKU features a CA pivot clevis back cover, allowing the body to swing on a pin to accommodate arcing or angular loads without binding. A screw-adjustable pneumatic air cushion at both ends replaces the standard fixed rubber bumper, letting you tune end-of-stroke deceleration to protect the end covers on aggressive moves.
Because this specific configuration lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. The riveted rolling-packed aluminum barrel keeps the overall envelope compact and lightweight for tight assembly spaces, while the heterogeneous two-way grease-retaining piston seal maintains consistent lubrication over high-frequency cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X20CA Is Used
Pivoting Press Stamper
Drives a short 20 mm stamping head on a packaging line, using the CA clevis to swing freely as the tooling arcs, while the cushion absorbs the 628 N impact to prevent cover fracture.
Sorting Diverter Arm
Actuates a rotary diverter gate on a parcel logistics belt, where the compact riveted body fits between rollers and the tuned cushion halts the rapid 20 mm throw without a jarring rubber bounce.
PCB Edge Guide
Pushes a delicate printed circuit board into a testing fixture, relying on the adjustable needle to gently slow the 40 mm bore piston before contact, protecting the 16 mm hard-chrome rod from side-shock.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X20CA the Right Cylinder?
If 528 N of pull at 0.5 MPa is excessive for your fixture, step down to the 32 mm bore, which provides 346 N of pull force. Conversely, if your load requires more authority, the 50 mm bore offers 881 N of pull force. The adjustable air cushion on this MBLC model is specifically warranted over the base fixed-bumper MBL when your short-stroke application cycles rapidly or moves a heavier mass that would quickly destroy a rubber stop. Remember that the pneumatic cushion only decelerates the piston near the stroke ends; it is not a brake and will not hold the load if air pressure drops or the valve centers. For exact replacement, match the 40 mm bore, 20 mm stroke, PT port thread, M12x1.25 rod end, CA pivot back cover, and the absence of a 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 MBLC40X20CA FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, push increases to 880 N, with a maximum theoretical output of 128 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod, and an M12x1.25 rod-end thread.
The screw-adjustable air cushion at both ends lets you tune the deceleration rate to match your load and speed, cutting vibration and end-cover impact that a fixed rubber bumper cannot absorb on fast cycles. This cushion only decelerates near the stroke ends; it is not a lock. The cylinder will drift if air is lost, and because this SKU lacks the -S magnet, no CMSG, DMSG, or EMSG sensor can be fitted for position detection.
