About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-30
The AirTAC MBLCJ32X40-30 is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 402 N of push force at 0.5 MPa. The rear stopper allows you to trim up to 30 mm of travel, creating a usable stroke window of 10 to 40 mm for exact end-position tuning.
Unlike the fixed rubber bumper found on the MBLJ series, the screw-tunable cushion valves on this unit decelerate heavier loads near the end caps, protecting the end covers from impact damage. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The Ø12 mm hard-chrome plated carbon-steel rod and riveted rolling-packed barrel ensure durable, leak-free performance in tight spaces.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-30 Is Used
PCB Depaneling Saw Feed
Uses the 10-40 mm stroke window to precisely set the cutting depth of a circular saw on an electronics assembly line, while the air cushion prevents abrupt stops that could crack the board.
Labeler Tamp Head
Dialing in the exact 25 mm tamp stroke for applying labels to small cosmetic boxes, relying on the 402 N force to press the label firmly without crushing the cardboard.
Textile Loom Yarn Guide
Cycles rapidly at 30-800 mm/s to shift a yarn guide back and forth, utilizing the tunable cushion valves to decelerate the rod smoothly and prevent tension snaps in the thread.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X40-30 the Right Cylinder?
For lower force needs, stepping down to the 25 mm bore yields 245 N of push force at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N if your payload demands more thrust. Choose this MBLCJ model over the MBLJ when your application moves sufficient mass to require tuned end-of-stroke deceleration. Choose the MBLC variant if you need this exact cushioning but have no requirement to trim the stroke length.
Remember that the rear adjuster is a travel stop, not a mechanical lock; it sets the end position but does not hold the load against external forces, which requires an external guide or locking device. Mounting is limited to Basic, FA flange, or LB foot styles, as the MBLCJ series does not support SDB pivots or back-cover options. The direct replacement match is a 32 mm bore, 40 mm stroke, 30 mm adjust code, G1/8 PT port, no magnet, and no specific mounting hardware included by default.
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 MBLCJ32X40-30 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. The maximum theoretical force is 82 kgf when operated at the 1.0 MPa pressure limit.
This specific SKU does not have a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position switches. Additionally, the rear adjuster functions only as a travel stop to set your 10-40 mm stroke window; it is not a lock and will not hold the load in place without live air pressure.
