The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X75-20S is a genuine double-acting aluminum-barrel mini cylinder with a Ø32mm bore, a 75mm nominal stroke and a rear adjustable-stroke stopper — trim up to 20mm for a usable window of 55–75mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ32X75-20S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. The rear stopper trims up to 20 mm of travel, creating a usable extension window of 55 to 75 mm. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is built for mid-range actuation where precise end-positioning is required. It includes a built-in magnet (-S) for solid-state DMSG or reed CMSG sensor integration.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable cushion on this MBLCJ allows you to regulate end-of-stroke deceleration, absorbing kinetic energy to protect the end covers during faster cycling. The 12 mm carbon-steel rod features 20 µm hard-chrome plating, and the riveted rolling-packed barrel utilizes a heterogeneous two-way grease-retaining piston seal. Note that the rear stopper sets the travel end and the cushion only decelerates; neither component mechanically locks the load in place.

Holds printed circuit board panels securely during routing operations. The 402 N clamping force prevents panel shifting, while the 55-75 mm stroke window allows exact height matching for varying stack thicknesses.
Drives the applicator head in packaging lines. The 20 mm rear stroke adjustment permits on-the-fly tuning of the extension distance without moving the cylinder mount, ensuring precise label placement.
Actuates a yarn guide bar across a knitting machine. The adjustable air cushion decelerates the 346 N pull force at stroke ends, preventing sudden jerks that would snap delicate synthetic threads.
Choose this 32 mm bore when an application demands 402 N of push force at 0.5 MPa within a 55-75 mm stroke window. If your payload is lighter, stepping down to the 25 mm bore drops the output to 245 N, whereas upgrading to the 40 mm bore increases push force to 628 N. The adjustable air cushion makes this series preferable over the MBLJ when moving heavier masses at higher speeds, as the cushion actively bleeds trapped air to prevent end-cover impact. For fixed-stroke tasks without the rear trimmer, select the MBLC variant.
When replacing this cylinder, match the 32 mm bore, 75 mm nominal stroke, 20 mm adjust code, G1/8 port, M10x1.25 rod thread, and the -S magnet. Mounting is restricted to Basic, FA, or LB styles; this series does not accept SDB pivots or back-cover codes. Because the 75 mm stroke is well within the 500 mm maximum standard for this bore, side-load risks are minimal, but external guides should still support any lateral forces to prevent bending the 12 mm rod.
Quick checklist
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.
The rear stroke adjustment is a mechanical travel stop that limits the rod extension, creating a 55-75 mm usable window for this specific model. The adjustable air cushion, located at both ends, uses a needle screw to tune end-of-stroke deceleration. Neither the stopper nor the cushion acts as a mechanical lock to hold the load.
