About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-40
The AirTAC MBLCJ40X100-40 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 40 mm of travel, creating a usable stroke window of 60 to 100 mm for precise end-position tuning. This 100 mm stroke suits mid-range indexing and robust clamping tasks.
Unlike the fixed rubber bumper on the base MBLJ, the screw-tunable air cushion here decelerates heavier loads at the stroke ends, protecting the end covers and allowing faster cycle speeds. The cylinder uses a Ø16 mm hard-chrome plated carbon-steel rod, a riveted rolling-packed aluminum barrel, and a grease-retaining piston seal. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-40 Is Used
Stamping Press Feeders
Drives raw metal blanks into a progressive die with 628 N of push force, relying on the adjustable air cushion to absorb the sudden halt at the 100 mm stroke end without slamming the cover.
Packaging Machine Plungers
Trims the rear stroke by 40 mm to create a 60 mm exact folding depth for varying carton sizes, using the tunable deceleration to prevent tearing the cardboard at high speeds.
Woodworking Clamp Jigs
Secures dense hardwood panels during routing operations, using the 528 N pull force to hold the jig while the cushioning softens the retraction impact to protect the fixture alignment.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-40 the Right Cylinder?
If you need less force, stepping down to the 32 mm bore drops the 0.5 MPa push force to 402 N. If your application requires more power, stepping up to the 50 mm bore increases it to 981 N. Choose this MBLCJ variant over the MBLJ when your moving mass demands tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC if you need the 60-100 mm adjustable travel window rather than a fixed stroke. Remember that the rear adjuster is a travel stop, not a lock; the cushion only decelerates and neither holds the load. A plain cylinder drifts without live air, so use an external locking device for strict position holding.
Mounting is limited to Basic, FA flange, or LB foot styles; there is no back-cover or SDB pivot option available. The overall length extends by the 40 mm adjuster on top of the standard dimensions. For an exact replacement, match the 40 mm bore, 100 mm stroke, 40 mm adjust code, G1/4 port, PT thread, and confirm no magnet is required. Since this stroke is under the 500 mm maximum standard, it is a standard catalog length, though external guides are still recommended for side-load stability.
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 MBLCJ40X100-40 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, with a maximum theoretical output of 128 kgf at 1.0 MPa. It uses a G1/4 port and a Ø16 mm rod with an M12x1.25 rod-end thread.
No, this specific SKU does not have a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors. The 40 mm rear adjustment is a travel stop that sets your 60-100 mm usable window, and the air cushion handles deceleration; neither component acts as a lock to hold the load in place.
