The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-30S is a genuine double-acting aluminum-barrel mini cylinder with a Ø32mm bore, a 450mm nominal stroke and a rear adjustable-stroke stopper — trim up to 30mm for a usable window of 420–450mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ32X450-30S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and tunable air cushions at both ends. It delivers 402 N of push force at 0.5 MPa via a Ø12 mm hard-chrome plated carbon-steel rod. The built-in magnet (-S) enables position detection across the 450 mm travel. A 30 mm rear trimmer sets a usable end-position window of 420-450 mm.
Unlike the base MBLJ with its fixed rubber bumper, this SKU uses screw-tunable end-of-stroke cushioning to decelerate heavy loads, protecting the end covers. The riveted rolling-packed barrel and grease-retaining piston seal maintain performance at 30-800 mm/s. Remember, the rear adjuster is a mechanical travel stop, not a load lock; the cushion only decelerates and cannot hold position without live air.

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.

Drives the 450 mm reed motion on a weaving loom, using the tunable air cushion to silently decelerate the 402 N push force at high cycling speeds without jarring the frame.
Indexes packaged goods onto a secondary packaging line, utilizing the 420-450 mm adjustable window to dial in the exact push distance for varying carton sizes.
Applies precise 346 N pull force to seat motherboard edge connectors, relying on the DMSG electronic sensor switch to confirm the retracted position before downstream robotic placement.
Delivering 402 N push at 0.5 MPa, stepping down to the 25 mm bore yields 245 N, while the 40 mm bore provides 628 N for heavier demands. Choose MBLCJ over the MBLJ when your moving mass requires tunable pneumatic deceleration rather than a fixed bumper, or over the MBLC if you need to fine-tune the end position. Ensure your replacement matches: 32 mm bore, 450 mm stroke, 30 mm adjust, G1/8 PT port, Basic/FA/LB mounting, and the -S magnet. Mounting is restricted to Basic, FA, or LB; no SDB or back-cover options exist.
At 450 mm, the overall length grows significantly (A + 2 x stroke + adjust). The small 12 mm rod is highly susceptible to side-load bending over this distance, so an external guide rail is mandatory to prevent premature seal wear. Neither the rear stopper nor the cushion acts as a lock; a separate external guide must carry the load weight.
Quick checklist
At 0.5 MPa, it provides 402 N push and 346 N pull. At 0.7 MPa, push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
The rear adjustable stroke is a mechanical stop that trims the end position within a 420-450 mm window. The adjustable air cushion is a screw-tunable valve that controls end-of-stroke deceleration. Neither holds the load; both require live air to function.
