About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X30-10S
The AirTAC MBLCJ40X30-10S 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 built-in magnet (-S) enables precise rod position detection using CMSG reed switches or DMSG and EMSG solid-state sensors.
This SKU features a 10 mm rear stroke adjuster, creating a usable travel window of 20 to 30 mm. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal ensure lasting smooth operation. Unlike the standard MBLJ with its fixed rubber bumper, the screw-tunable air cushion on this 40 mm bore allows you to finely decelerate heavier loads near the stroke ends, protecting the end covers from impact damage.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X30-10S Is Used
PCB Drill Spindle Lifter
Lifts a precision spindle carriage 25 mm using the 628 N push force, relying on the adjustable air cushion to prevent harsh end-impact during rapid 800 mm/s indexing.
Label Applicator Stroke Trim
Trims the rear stroke by 10 mm for a 20 mm exact label wipe stroke, using the built-in magnet to trigger a DMSG sensor for repeatable glue dispensing.
Small Punch Press Ejector
Ejects stamped metal clips using 528 N of pull force, where the tunable end-cushioning absorbs the sudden deceleration of the 16 mm hard-chrome rod.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X30-10S the Right Cylinder?
If you need less force, the 32 mm bore variant provides 402 N of push force at 0.5 MPa, while stepping up to the 50 mm bore yields 981 N. This MBLCJ40X30-10S is ideal when you need the 628 N output but have a very tight 20-30 mm effective stroke window. The rear adjuster acts purely as a mechanical travel stop; it does not lock or hold the load in place, so external locking mechanisms are required for strict position holding. Mounting is limited to Basic, FA flange, or LB foot styles, as the MBLCJ series lacks back-cover or SDB pivot options. To match this exact replacement, verify the 40 mm bore, 30 mm nominal stroke, 10 mm adjust code, G1/4 port, PT thread, and the -S magnet.
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 MBLCJ40X30-10S FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N push and 528 N pull force. At 0.7 MPa, the push force reaches 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The rear stroke adjuster mechanically trims the travel end, creating a 20-30 mm usable stroke window from the 30 mm nominal stroke. The adjustable air cushion only tunes the end-of-stroke deceleration speed. Neither system locks or holds the load in place.
