About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X150U
The AirTAC MBLC40X150U is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making the 150 mm stroke well-suited for mid-length indexing and part ejection tasks. The U suffix denotes a rigid flat-end back cover for direct mounting.
Unlike the base MBL bumper design, this MBLC variant allows you to tune end-of-stroke deceleration, actively protecting the end covers during high-frequency or heavier mass transfers. The body utilizes a riveted rolling-packed aluminum barrel for a compact footprint, paired with a 20 µm hard-chrome carbon-steel rod and a heterogeneous two-way grease-retaining piston seal to maintain lubrication over long service cycles. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X150U Is Used
CNC Lathe Bar Feeder
Pushes raw bar stock into the collet with 628 N of force at 0.5 MPa, utilizing the 150 mm stroke and tuned air cushion to prevent harsh mechanical jerks during rapid stock indexing.
Packaging Lane Diverter
Diverts filled cardboard cartons on a conveyor using the flat-end U cover, where the adjustable cushion ensures smooth retraction without bouncing the actuator at high cycle rates.
PCB Test Handler
Positions electronic test fixtures over a moving board; the riveted aluminum body keeps the envelope small while the cushion needle damps the 150 mm travel for precise, vibration-free stops.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC40X150U the Right Cylinder?
When sizing this 40 mm bore, step down to the 32 mm bore if your load requires less force (it provides 402 N push at 0.5 MPa), or step up to the 50 mm bore for heavier payloads (delivering 981 N push at 0.5 MPa). Choose this MBLC model over the standard MBL when your cycle speeds exceed what a fixed rubber bumper can absorb without causing impact damage. The U flat-end back cover provides rigid rear mounting; select a CA pivot cover instead if your mechanism requires angular alignment. For replacement matching, specify the 40 mm bore, 150 mm stroke, G1/4 port, PT thread, U back cover, and no magnet. Because the 150 mm stroke is substantial, the 16 mm rod has limited side-load tolerance; use an external guide rail, an SDB pivot bracket, or an 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 MBLC40X150U FAQ
This 40 mm bore cylinder delivers 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. It features a G1/4 port, a 16 mm rod, and operates at speeds of 30-800 mm/s.
The cushion is a screw-tunable pneumatic needle at both ends that decelerates the piston near stroke limits to reduce impact; it is not a load lock or brake. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensor switches for position detection.
