About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-10
The AirTAC MBLCJ40X150-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a usable stroke window of 140-150 mm for exact end-positioning. A G1/4 port feeds the 40 mm bore, while the Ø16 carbon-steel rod is plated with 20 µm hard chrome to resist wear and scoring.
Unlike the base MBLJ which relies on a fixed rubber bumper, this SKU uses screw-tunable air cushions to decelerate heavier loads smoothly near each end of the 150 mm stroke. The riveted rolling-packed barrel and grease-retaining piston seal keep friction low across the 30-800 mm/s speed range. Note that this specific configuration lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-10 Is Used
Packaging Carton Flaps
Drives a folding mechanism on a packaging line, using the 628 N push force to cleanly fold heavy corrugated cardboard flaps before sealing.
CNC Lathe Door Damping
Cycles a heavy sliding safety door, relying on the adjustable air cushion to prevent harsh slamming at the end of the 150 mm travel.
Small Press Ejector
Ejects stamped metal parts from a 40-ton press, utilizing the 140-150 mm adjustable stroke window to time the ejection precisely.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-10 the Right Cylinder?
Choose this 40 mm bore if your application requires around 628 N of push force at 0.5 MPa. If your load is lighter, stepping down to the 32 mm bore yields 402 N of push force, while stepping up to the 50 mm bore provides 981 N for heavier demands. This MBLCJ model is preferred over the MBLJ when you need tunable end-of-stroke deceleration instead of a fixed bumper, and over the MBLC when you need the 10 mm rear travel adjustment rather than a fixed total stroke.
Remember that the rear adjuster is a travel stop, not a lock, and the air cushion only decelerates motion—neither will hold a load in place without continuous air pressure. Mounting options are limited to Basic, FA flange, or LB foot brackets, as this series does not accept SDB pivot or back-cover attachments. For an exact replacement, match the 40 mm bore, 150 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and no-magnet configuration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X150-10 FAQ
At 0.5 MPa, the 40 mm bore generates 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The cylinder has a maximum theoretical force of 128 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The adjustable stroke is a mechanical rear stopper that physically limits the rod travel, providing a usable window of 140-150 mm by trimming up to 10 mm. The adjustable air cushion is a separate screw-tunable valve that controls exhaust flow to decelerate the load near the end caps. Neither feature locks or holds the load in place without live air pressure.
