About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X200-100S
The AirTAC MBLCJ20X200-100S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and a screw-tunable air cushion at both ends. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. The 100 mm adjuster code trims the rear travel stop, creating a usable 100-200 mm stroke window for precise end-positioning.
This model includes a built-in magnet for CMSG, DMSG, or EMSG sensor switches. Unlike the fixed rubber bumper on an MBLJ, the adjustable air cushion allows you to tune end-of-stroke deceleration for faster cycling while protecting the covers. The riveted rolling-packed barrel and 20 um hard-chrome plated Ø8 carbon-steel rod handle speeds up to 800 mm/s.

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)

|---|---|---|
| 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 MBLCJ20X200-100S Is Used
PCB Depaneling Saw
Feeds a circular saw blade at a controlled 100-200 mm window, using the tunable air cushion to decelerate the 157 N push force before the cut finishes, preventing board edge chipping.
Dispenser Valve Metering
Drives a precision needle valve for two-part epoxy, relying on the rear stopper to set the exact shot size and the DMSG electronic sensor to confirm the dispense stroke completed.
Wire Straightener Tensioner
Acts as a floating tension arm in a wire drawing machine, using the 132 N pull force to maintain constant tension while the cushion absorbs rapid direction changes without shock.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X200-100S the Right Cylinder?
For lower force needs, stepping down to the 20 mm bore's only smaller neighbour is not an option, but stepping up to a 25 mm bore yields 245 N push at 0.5 MPa. Choose this MBLCJ over the MBLJ when you need tunable end-deceleration rather than a fixed bumper, or over an MBLC when you require a rear travel stopper. Remember, the rear adjuster is a mechanical travel stop, and the cushion only decelerates; neither holds the load, so use an external guide for the long 200 mm stroke. Replacement matches: 20 mm bore, 200 mm stroke, 100 mm adjust, G1/8 port, PT thread, Basic/FA/LB mounting, and -S 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 MBLCJ20X200-100S FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N push and 132 N pull force. At 0.7 MPa, push increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The 100 mm adjustable stroke is a rear mechanical stopper that sets your travel end within a 100-200 mm window, but it does not lock or hold the load. The adjustable air cushion is a separate screw that tunes end-of-stroke deceleration to protect the end covers; it is not a brake.
