About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X25-30S
The AirTAC MBLCJ32X25-30S is a compact double-acting mini cylinder featuring a riveted aluminum barrel and a single Ø12 mm hard-chrome plated carbon-steel rod. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa, making it well-suited for mid-force positioning tasks on automated machinery. A built-in magnet (-S) enables position detection using CMSG reed switches or DMSG/EMSG solid-state sensors.
This model combines a rear adjustable stroke stopper with an adjustable air cushion at both ends. The rear stopper allows you to trim up to 30 mm of travel, creating a usable stroke window of 0 to 25 mm for precise end-position tuning. Unlike the base MBLJ which relies on a fixed rubber bumper, the screw-tunable air cushion lets you dial in end-of-stroke deceleration to protect the end covers and handle faster moves. The cushion only decelerates; it does not lock or hold the load.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X25-30S Is Used
PCB Drill Press Indexing
Provides 402 N of push at 0.5 MPa to position a drilling head, using the 0-25 mm stroke window to dial in the exact contact depth without shimming.
Label Applicator Tamp
Tunes the air cushion to softly press labels onto fragile glass vials at high speed, preventing impact cracks while the rear stopper sets the exact label position.
Diverter Gate Actuation
Handles mid-force package diversion on a conveyor, using the DMSG solid-state sensor to confirm gate extension before high-speed cartons arrive.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X25-30S the Right Cylinder?
If you need less force, stepping down to the 25 mm bore yields 245 N of push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N. Choose this MBLCJ over the MBLJ when your application requires tunable end-of-stroke deceleration rather than a fixed bumper, or over the MBLC when you need to trim the rear travel end. The rear adjuster sets the travel stop, and the cushion manages deceleration, but neither holds position pneumatically without live air. Mounting is limited to Basic, FA, or LB styles as there is no back-cover or SDB pivot option. For a direct replacement, match the 32 mm bore, 25 mm stroke, 30 mm adjust code, G1/8 PT port, 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 MBLCJ32X25-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa.
The rear stroke adjuster is a mechanical travel stop that lets you trim up to 30 mm of travel, giving a usable stroke window of 0 to 25 mm. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration to prevent hard impacts. Neither mechanism locks or holds the load in place pneumatically.
