About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X10-10
The AirTAC MBLCJ40X10-10 is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a Ø16 mm hard-chrome plated carbon-steel rod. It delivers 628 N push and 528 N pull force at 0.5 MPa. Equipped with a rear stroke adjuster, you can trim the 10 mm travel back to a zero-point, yielding a usable 0-10 mm movement window for extremely short-stroke tasks.
Unlike the base MBLJ which relies on a fixed rubber bumper, this model incorporates a screw-tunable adjustable air cushion at both ends to decelerate the load smoothly. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The rear stopper sets the travel end and the cushion governs end-deceleration, but neither acts as a mechanical lock to hold a load in place without live air pressure.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)

|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 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 MBLCJ40X10-10 Is Used
PCB Router Z-Axis Stop
Governs the plunge depth of a spindle on a small PCB routing machine, using the 0-10 mm window to dial in the exact cutting depth while the air cushion prevents bounce at the upper limit.
Pneumatic Press Micro-Adjust
Acts as a height-stop for a 628 N assembly press, allowing operators to fine-tune the crimping height of small bullet terminals without changing mechanical spacers.
Component Sealing Head
Drives a sealing head against blister pack openings, where the adjustable cushion absorbs the final 2 mm of impact to prevent crushing the plastic lidding material.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X10-10 the Right Cylinder?
If your process needs less force, stepping down to the 32 mm bore yields 402 N push at 0.5 MPa, whereas moving up to the 50 mm bore provides 981 N for heavier displacement. The MBLCJ is preferred over the MBLJ when you need to tune end-of-stroke deceleration to protect the end covers from impact, and over the MBLC when you require that rear travel-stop functionality.
Remember that the rear adjuster is a travel stop, not a brake; the cushion only decelerates, so external locking mechanisms are required for true position holding. Mounting is restricted to Basic, FA flange, or LB foot styles, as this series omits SDB pivot and back-cover options. To guarantee an exact replacement, match the 40 mm bore, 10 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and confirm no magnet is required.
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 MBLCJ40X10-10 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, and it reaches a maximum theoretical output of 128 kgf at 1.0 MPa.
The rear adjustment is a mechanical travel stop that trims the stroke from 0 to 10 mm, setting the exact end position. The adjustable air cushion only regulates the speed of deceleration near the stroke end to prevent hard impacts; neither feature locks or holds the load in place without continuous air pressure.
