About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-10
The AirTAC MBLCJ40X100-10 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. You can trim up to 10 mm of rear travel, yielding a usable stroke window of 90-100 mm. Driven by a Ø16 mm carbon-steel rod with 20 um hard-chrome plating, it generates 628 N of push force and 528 N of pull force at 0.5 MPa. This 100 mm travel is well-suited for medium-duty indexing and pressing tasks.
Unlike the base MBLJ which relies on a fixed rubber bumper, this SKU uses screw-tunable pneumatic cushioning to decelerate heavier loads smoothly at the stroke extremes, protecting the end covers from impact damage. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal ensure stable friction. Note that this specific configuration lacks a built-in magnet (-S), meaning it cannot accept a CMSG, DMSG, or EMSG position sensor. The rear travel stopper sets the end position; it is not a mechanical lock, so an external guide is needed for side-load compensation.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-10 Is Used
PCB Router Spindle
Provides 628 N of push force at 0.5 MPa to plunge a high-speed routing spindle into printed circuit boards, using the 90-100 mm stroke window to dial in the exact cut depth.
Bottle Capping Head
Applies 528 N of pull force to tighten threaded caps on a beverage line, relying on the adjustable air cushion to softly seat the capping head and prevent shattered glass.
Carton Flap Folder
Drives a mechanical flap-folding arm on a packaging conveyor, using the 100 mm stroke to clear the carton profile while the tunable cushion prevents hard stops at high cycle rates.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-10 the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, whereas moving up to the 50 mm bore provides 981 N for heavier loads. Choose this MBLCJ variant over the MBLJ when you need tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when your design requires trimming the rear travel. Keep in mind the rear adjuster is a travel stop, not a lock, and the cushion only decelerates; neither will hold a load in place without live air pressure. Mounting is restricted to Basic, FA, or LB styles, as there is no SDB or back-cover option. To match this exact replacement, verify: 40 mm bore, 100 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and no 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 MBLCJ40X100-10 FAQ
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The rear adjuster lets you mechanically trim the stroke end within a 90-100 mm window, acting as a travel stop rather than a load lock. The adjustable air cushion independently tunes end-of-stroke deceleration to prevent cover damage. Because this SKU lacks the -S magnet code, it cannot accept CMSG, DMSG, or EMSG electronic position sensors.
