About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X225CA
The AirTAC MBLC20X225CA is a compact double-acting aluminum mini cylinder engineered with a screw-tunable adjustable air cushion at both ends. Delivering 157 N of push force at 0.5 MPa, this 20 mm bore, 225 mm stroke unit is built for fast, repetitive motion where a fixed rubber bumper would fail. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the 20 µm hard-chrome plating on the carbon-steel Ø8 mm rod provides high wear resistance for tight-space machinery.
This specific SKU features a CA pivot/clevis back cover that swings on a pin to safely accommodate arcing or angular loads during travel. Because this configuration lacks the built-in magnet (no -S suffix), it cannot accept a CMSG, DMSG, or EMSG sensor switch for rod position detection. The heterogeneous two-way grease-retaining piston seal ensures consistent lubrication, and the pneumatic cushion needle lets you dial in end-of-stroke deceleration to cut impact shock and noise without acting as a load lock.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X225CA Is Used
PCB Component Insertion
Drives a delicate pick-and-place head inserting through-hole connectors into circuit boards, using the adjustable cushion to stop the 225 mm travel smoothly without jarring the fine solder joints.
Pouch Sorting Diverter
Swings on its CA clevis pin to arc a lightweight guide arm, pushing small food pouches from a main conveyor belt into a secondary packaging lane with precise 157 N force.
Semiconductor Wafer Cassette
Actuates a small loading fork inside a tight semiconductor equipment bay, requiring the compact riveted aluminum barrel to fit between densely packed cassette slots.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X225CA the Right Cylinder?
Select this 20 mm bore model when you need 157 N push (132 N pull) at 0.5 MPa in a tight envelope; if you need less force, the smaller 20 mm is the minimum available size, but if your payload requires more thrust, step up to the 25 mm bore which yields 245 N push at 0.5 MPa. Choose this MBLC over the base MBL when your cycle speeds exceed what a fixed rubber bumper can absorb without causing end-cover damage or excessive vibration. For replacement, match the 20 mm bore, 225 mm stroke, G1/8 port, PT thread, CA pivot back cover, and no-magnet configuration. At 225 mm of travel, the small Ø8 mm rod has low side-load tolerance; if your application generates lateral forces, use an external guide rail or switch to the MBLD double-rod cylinder to prevent rod bending.
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 MBLC20X225CA FAQ
This 20 mm bore cylinder uses an Ø8 mm rod with an M8x1.25 rod-end thread and a G1/8 port. The theoretical force output is 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet (-S suffix), so it cannot accept CMSG, DMSG, or EMSG sensor switches. The adjustable air cushion at both ends uses a screw needle to restrict exhaust flow, decelerating the piston smoothly near stroke ends to protect the end covers on fast cycles; it is a tunable shock absorber, not a load lock or brake.
