About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X175-20S
The AirTAC MBLCJ32X175-20S is a compact double-acting mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The rear stopper allows you to trim up to 20 mm of travel, creating a usable stroke window of 155 to 175 mm. Driven by a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating, it delivers 402 N of push force and 346 N of pull force at 0.5 MPa. The riveted aluminum barrel and two-way grease-retaining piston seal ensure reliable operation in tight, space-constrained machinery.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant uses screw-tunable end-of-stroke cushioning to decelerate heavier loads smoothly, protecting the end covers from impact. The built-in magnet (-S) supports position detection via CMSG reed switches or DMSG/EMSG solid-state sensors. Note that the rear adjuster is a travel stop, not a mechanical lock, so an external guide is recommended for side-load stability on this 175 mm stroke.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 MBLCJ32X175-20S Is Used
PCB Router Z-Axis
Drives the vertical plunge of a printed circuit board depaneling router, using the 155-175 mm window to dial in the exact cutting depth while the air cushion absorbs end-of-travel shock.
Textile Tentering Frame
Actuates the edge-guide clamp on a fabric stretching machine, relying on the 402 N push force to hold woven material taut and the cushioning to prevent vibration at high speeds.
Bottle Capper Head
Lowers a screw-capping chuck onto plastic bottles, using the 20 mm rear stroke adjustment to compensate for different cap heights without repositioning the entire bracket.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X175-20S the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push @0.5 MPa); if your payload requires more thrust, step up to the 40 mm bore (628 N push @0.5 MPa). Choose the MBLCJ over the MBLJ when your cycle speeds demand tunable deceleration rather than a fixed rubber bumper, or choose the MBLC if you prefer a fixed stroke without the rear adjuster. Remember that neither the rear adjuster nor the air cushion will hold a load in place without continuous air pressure, so use an external locking mechanism for true position holding.
Mounting is limited to Basic, FA (flange), or LB (foot) configurations; SDB pivot and back-cover options are not available on this series. To replace this exact unit, match the 32 mm bore, 175 mm stroke, 20 mm adjust code, G1/8 port, PT thread, and the -S magnet. The overall length follows the A + 2 x stroke + adjust formula, yielding a longer body than a fixed-stroke cylinder.
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 MBLCJ32X175-20S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
The adjustable stroke is a rear travel stopper that physically limits the rod extension from 155 to 175 mm. The adjustable air cushion is a screw-tunable valve that decelerates the piston near the end caps. Neither feature locks the load; the rod will drift if air pressure is lost, so an external brake is required for position holding.
