About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-30S
The AirTAC MBLCJ40X100-30S 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 30 mm rear trimmer allows you to tune the usable travel window from 70 to 100 mm, giving you exact end-position control without machining new mountings. A built-in magnet (-S) enables position detection using CMSG reed switches or DMSG and EMSG solid-state sensors.
Unlike the fixed rubber bumper found on the base MBLJ, this model uses screw-tunable end-of-stroke cushioning to decelerate heavier loads, protecting the aluminum end covers from impact. The riveted rolling-packed barrel and 20 um hard-chrome plated carbon-steel rod withstand demanding cycles. The rear stopper sets the travel end but does not hold the load; the cylinder relies on live air to maintain position, and the cushion only governs deceleration speed.

| 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 MBLCJ40X100-30S Is Used
PCB Router Z-Axis
Governs the plunge depth of a spindle on a printed circuit board routing machine, using the 70-100 mm window to dial in exact cutting depth while the air cushion prevents hard stops at the board surface.
Bottle Capper Head
Applies 628 N of downward force to press aluminum caps onto glass beverage bottles, utilizing the tunable cushion to soften the contact impact and prevent bottle breakage during high-speed runs.
Leather Skiving Feed
Drives the feed roller on a leather skiving machine, where the 30 mm rear adjustment accommodates varying thicknesses of hides and the cushion protects the geartrain from end-of-stroke shock.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X100-30S the Right Cylinder?
If 628 N of push at 0.5 MPa is too much force, step down to the 32 mm bore, which provides 402 N of push force. If your application requires more power, step up to the 50 mm bore, offering 981 N of push. Choose this MBLCJ over the MBLJ when you need tunable deceleration rather than a fixed bumper, or choose the MBLC variant if you require a fixed standard stroke without the rear adjuster.
For a direct replacement, match the 40 mm bore, 100 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and the -S magnet. Mounting is limited to Basic, FA flange, or LB foot options; there is no SDB pivot or back-cover configuration available. The overall length equals A plus twice the stroke plus the 30 mm adjuster. Because the adjuster is a travel stop and the air cushion is not a lock, use an external guide or locking mechanism if the load must be held securely in place.
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 MBLCJ40X100-30S 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 is a mechanical travel stop that lets you trim the stroke window from 70 to 100 mm, but it does not lock or hold the load in place. The adjustable air cushion at both ends is a screw-tunable valve that regulates exhaust flow to decelerate the piston near the end caps, protecting the cylinder from impact damage.
