About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X250-75
The AirTAC MBLCJ32X250-75 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 and 346 N of pull force at 0.5 MPa. The 75 mm rear stopper trims the travel end, creating a usable stroke window of 175 to 250 mm. This extended travel suits long-transfer tasks on packaging lines. Tuning the end-of-stroke cushioning allows faster actuation speeds without slamming the end covers, a distinct advantage over the fixed rubber bumper found on the MBLJ series.
This SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The Ø12 mm hard-chrome plated carbon steel rod operates within a riveted rolling-packed aluminum barrel, utilizing a heterogeneous two-way grease-retaining piston seal. The rear adjustment screw sets the travel limit but does not lock the load in place; external mechanics are required for position holding. With a 250 mm stroke, the small 12 mm rod is susceptible to side-loading, so an external guide rail should be used to prevent rod bending.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X250-75 Is Used
Carton Flap Folding
Drives a 250 mm arm to fold heavy corrugated cardboard flaps on a packaging conveyor, using the 75 mm rear adjuster to fine-tune the 175-250 mm travel window for varying box sizes.
Pallet Strapping Press
Extends to tension and guide steel strapping around pallets, relying on the adjustable air cushion to decelerate the 402 N push force smoothly at the end of the long stroke.
Textile Beam Indexing
Shifts large fabric beams laterally between processing stations, where the lack of a magnet is irrelevant and the fixed rear stopper ensures a consistent mechanical end position.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X250-75 the Right Cylinder?
Select this 32 mm bore when an application requires 402 N push at 0.5 MPa over a long distance with variable end positioning. If your payload is lighter, stepping down to the 25 mm bore yields 245 N push force and a shorter overall length. If you need to move heavier jigs, stepping up to the 40 mm bore provides 628 N push force. Because this is a 250 mm stroke, the 12 mm rod needs external guidance to prevent bending under lateral stress. Mounting is limited to Basic, FA flange, or LB foot styles; there is no SDB pivot or back-cover option. The replacement match is a 32 mm bore, 250 mm stroke, 75 mm adjust code, with a G1/8 PT port and no magnet. The rear adjuster is a travel stop, and the cushion only decelerates; neither function acts as a mechanical brake.
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 MBLCJ32X250-75 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push and 346 N pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
This specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. The 75 mm rear screw adjusts the usable stroke window from 175 to 250 mm, but it is only a travel stop. The adjustable air cushion only decelerates the piston near the end covers; neither feature locks or holds the load in place.
