About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X175-100
The AirTAC MBLCJ20X175-100 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and screw-tunable air cushions at both ends. It delivers 157 N push and 132 N pull at 0.5 MPa. The 100 mm rear adjuster yields a usable 75-175 mm travel window, ideal for varying machine format changes.
Unlike the fixed bumper on an MBLJ, this cushion actively decelerates the rod near the stroke ends to absorb kinetic energy. The riveted rolling-packed barrel and 20 um hard-chrome plated Ø8 carbon-steel rod resist wear, while the heterogeneous two-way grease-retaining piston seal maintains lubrication. Note this SKU lacks a built-in magnet, so it cannot accept CMSG or DMSG position sensors.

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 MBLCJ20X175-100 Is Used
PCB Shuttle Conveyors
Drives a 175 mm shuttle stroke in PCB handling lines, using the 100 mm rear adjuster to fine-tune board handoff distance while the air cushion softens the end-of-stroke stop.
Packaging Format Change
Adjusts the 75-175 mm travel window on small pouch sealing machines to accommodate varying package widths without swapping the entire cylinder body.
Pick-and-Place Dampening
Executes rapid horizontal part transfers in compact assembly cells, relying on the tunable end cushions to prevent the 8 mm rod from shocking the aluminum end covers at high speed.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X175-100 the Right Cylinder?
For lower force needs, step down to a 20 mm bore only if dropping below 157 N is acceptable; otherwise, step up to the 25 mm bore (245 N push at 0.5 MPa) for heavier resistance. Choose this MBLCJ over the MBLJ when your application speed demands active deceleration rather than a fixed rubber bumper, or over the MBLC if you need format flexibility via the 75-175 mm adjustable window. The rear adjuster sets the travel end and the cushion controls deceleration, but neither acts as a lock to hold a load—use an external locking device for position holding. Mounting is limited to Basic, FA, or LB; no SDB or back-cover options exist. Replacement match: 20 mm bore, 175 mm stroke, 100 mm adjust, G1/8 port, PT thread, no 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 MBLCJ20X175-100 FAQ
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa the push is 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
The 100 mm rear adjuster acts as a mechanical travel stop, creating a usable 75-175 mm stroke window, but it does not lock or hold the load. The adjustable air cushion at both ends only controls end-of-stroke deceleration to protect the end covers; it also is not a lock.
