About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X175-10
The AirTAC MBLCJ20X175-10 is a compact double-acting aluminum mini cylinder featuring a rear travel stopper and screw-tunable air cushions at both ends. The rear adjuster trims up to 10 mm of travel, creating a usable end-position window of 165 to 175 mm. Driven by a Ø8 mm hard-chrome rod, it delivers 157 N of push force and 132 N of pull force at 0.5 MPa, making it suited for light-load positioning tasks over its 175 mm stroke.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant lets you dial in end-of-stroke deceleration to absorb kinetic energy and protect the covers during faster cycles. The riveted rolling-packed barrel and heterogeneous two-way grease-retaining piston seal keep operating friction low. This specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensing without physical modification. The rear stopper sets the travel end but does not lock the load in place.

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 MBLCJ20X175-10 Is Used
PCB Router Z-Axis
Drives a light spindle head across the 165-175 mm window; the tunable air cushion prevents end-cover shock during rapid routing plunges.
Dispenser Valve Tensioning
Applies 157 N of push force to seat a fluid dispenser valve against a manifold, with the rear stopper providing exact 10 mm depth trimming.
Indexing Conveyor Diverter
Pushes small electronic totes along a belt line; the cushioning screw slows the rod before impact to avoid jarring delicate chip packages.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X175-10 the Right Cylinder?
With a 157 N push force at 0.5 MPa, this 20 mm bore sits at the smallest end of the MBLCJ range. If your application needs less force, you must look outside this series, but if you need more power, stepping up to the 25 mm bore yields 245 N of push force. Choose this MBLCJ over the MBLJ when your moving mass requires tunable deceleration rather than a fixed bumper, or over the MBLC if you need the 10 mm rear stroke trim. Remember that the adjustable stroke mechanism is a travel stop, not a lock; the cylinder cannot hold a load without live air pressure, and the cushion only decelerates.
Mounting is restricted to Basic, FA flange, or LB foot styles; this series does not offer SDB pivot or back-cover options. The overall length is extended by the 10 mm adjuster, and the 175 mm stroke on an Ø8 mm rod warrants an external guide to prevent side-load bending. For a direct replacement, match the 20 mm bore, 175 mm stroke, 10 mm adjust code, G1/8 port, default PT thread, and the absence of 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 MBLCJ20X175-10 FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
This specific SKU does not have a built-in magnet (-S), so it cannot accept AirTAC CMSG, DMSG, or EMSG position switches. The 10 mm rear adjuster functions as a travel stop to set the 165-175 mm end position, but it does not lock or hold the load; the air cushion only decelerates the piston.
