About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X200-10S
The AirTAC MBLCJ20X200-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 157 N of push force at 0.5 MPa. The rear stopper allows you to trim up to 10 mm of travel, creating a precise 190-200 mm usable stroke window for exact end-of-cycle positioning.
Unlike the fixed rubber bumper on a standard MBLJ, the screw-tunable air cushion on this unit decelerates the rod near the stroke ends, protecting the end covers during faster cycling. The built-in magnet (-S) supports CMSG reed and DMSG or EMSG solid-state sensors for position detection. Because the 200 mm stroke is relatively long for the 8 mm rod, an external guide is recommended to prevent side-load bending.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 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 MBLCJ20X200-10S Is Used
PCB Edge Routing
Drives a light routing head across a 190-200 mm window, using the adjustable air cushion to prevent end-impact jitter on delicate circuit boards.
Label Applicator
Trims the rear stroke by 10 mm to hit a precise wipe distance for applying labels, relying on the 157 N push force to maintain contact pressure.
Small Parts Ejection
Ejects lightweight plastic molded parts from a cavity at high speed, using the tunable cushion to decelerate the 8 mm rod smoothly before the end cover.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X200-10S the Right Cylinder?
For lower force needs, stepping down to a bore 16 (if available in your series) or choosing a different frame reduces footprint, but stepping up to the 25 mm bore yields 245 N push at 0.5 MPa for heavier loads. Choose this MBLCJ over the MBLJ when your application requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need the 10 mm rear stroke adjustment window.
The rear adjuster sets the travel end point, while the cushion only controls deceleration; neither acts as a lock to hold a load, so external holding mechanisms are required for suspended masses. Mounting is limited to Basic, FA, or LB styles, as this series omits SDB and back-cover options. The exact replacement match is a 20 mm bore, 200 mm stroke, 10 mm adjust code, G1/8 PT thread, with the -S magnet fitted.
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 MBLCJ20X200-10S FAQ
At 0.5 MPa, it provides 157 N push and 132 N pull force. At 0.7 MPa, the push force is 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The 10 mm rear adjuster creates a usable stroke window of 190-200 mm.
No. The rear adjuster acts only as a travel stop to set the end position, and the adjustable air cushion only regulates deceleration speed near the covers. Neither component functions as a lock or brake, so an external holding device is needed to maintain position under load.
