About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350U
The AirTAC MBLC20X350U is a double-acting aluminum mini cylinder engineered with a screw-adjustable air cushion at both ends. Generating 157 N of push force at 0.5 MPa from its 20 mm bore, it uses a G1/8 port and an 8 mm carbon-steel rod with 20 µm hard-chrome plating. The 350 mm stroke suits extended travel in tight spaces, while the U flat-end back cover provides a rigid rear mounting face.
Unlike the base MBL’s fixed rubber bumper, this MBLC variant lets you tune the pneumatic cushion needle to smoothly decelerate the piston near stroke ends, cutting impact shock on faster moves. The riveted rolling-packed aluminum barrel keeps the body compact and light. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350U Is Used
PCB Depaneling Router
Drives a cutting head across 350 mm to singulate printed circuit boards, using the adjustable cushion to brake the 8 mm rod gently and avoid jarring sensitive electronic traces.
Pouch Indexing Gate
Extends a diverter blade 350 mm on a packaging line, relying on the tunable air cushion to absorb the end-of-stroke kinetic energy from the fast-moving 157 N push load.
Lab Sample Dispenser
Moves a pipette array across testing stations, where the compact riveted aluminum body fits tight machine envelopes and the cushion prevents fluid splashing from sudden stops.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350U the Right Cylinder?
For lighter loads, step down to the 20 mm bore's smaller sibling if available, or for higher force 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 speed or load mass outgrows a fixed rubber bumper. At 350 mm of stroke, the 8 mm rod has low side-load tolerance; use an external guide, a pivot mount, or the MBLD double-rod type to prevent rod bending. Replacement match: 20 mm bore, 350 mm stroke, G1/8 port, PT thread, U back cover, no 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 MBLC20X350U FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa it yields 220 N push and 185 N pull. The theoretical maximum is 32 kgf at 1.0 MPa.
A screw-tunable needle at each end traps exhaust air to decelerate the piston near the stroke limits. You set the needle to match your load and speed, which protects the end covers from impact—unlike a non-adjustable fixed rubber bumper. It only decelerates near the ends and does not lock the rod.
