About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X100-75S
The AirTAC MBLCJ20X100-75S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. With a 20mm bore, it delivers 157N push and 132N pull force at 0.5 MPa. The rear stopper allows you to trim up to 75mm of travel, creating a usable 25-100mm end-position window for precise machinery timing.
This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensors. Unlike the fixed rubber bumper on an MBLJ, the screw-tunable air cushion lets you dial in end-of-stroke deceleration to absorb kinetic energy and protect the end covers. The riveted rolling-packed barrel and 20um hard-chrome plated carbon-steel rod withstand harsh cycling.

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 MBLCJ20X100-75S Is Used
PCB Drill Spindle Loader
Uses the 25-100mm adjustable window to set exact drill bit insertion depth, relying on the 157N push force and tunable air cushion to prevent impact damage on the spindle head.
Textile Yarn Guide Trim
Trims the stroke by 75mm to synchronize yarn guide positioning across changing fabric widths, while the magnetic piston triggers a DMSG sensor for loop control.
Small Parts Ejector
Fits into tight machine frames to eject small molded plastic parts, using the adjustable end cushion to slow the 8mm rod before hitting the end cover during high-speed cycling.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X100-75S the Right Cylinder?
The 20mm bore yields 157N of push force at 0.5 MPa. If your application requires less force, the smaller 16mm bore is not available in this series, so 20mm is the minimum. If you need more power, stepping up to the 25mm bore provides 245N of push force. Choose the MBLCJ over the MBLJ when your moving mass demands tunable deceleration rather than a fixed bumper, or the MBLC if you want fixed stroke lengths without a rear adjuster.
Remember that the rear adjuster is a travel stop, not a lock; it sets the end point but cannot hold a load in place without live air pressure. Mounting is limited to Basic, FA, or LB styles, as this series lacks a back-cover or SDB pivot option. To replace this SKU exactly, match the 20mm bore, 100mm stroke, 75mm adjust code, G1/8 port, PT thread, and the -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 MBLCJ20X100-75S FAQ
At 0.5 MPa, the push force is 157N and the pull force is 132N. At 0.7 MPa, the push force is 220N. The maximum theoretical force is 32 kgf at 1.0 MPa.
The rear adjustable stroke is a mechanical stopper that limits travel within a 25-100mm window. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration. Neither holds a load in place; they only set the end point and slow the rod.
