The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ32X450-40 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 40mm for a usable window of 410–450mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ32X450-40 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 rear stopper allows you to trim up to 40 mm of travel, creating a usable stroke window of 410 to 450 mm for exact end-positioning.
Unlike the fixed rubber bumper found on the MBLJ series, the screw-tunable air cushion on this unit decelerates heavy loads over a 450 mm extension, protecting the end covers from impact shock. The riveted rolling-packed aluminum barrel and 20 um hard-chrome plated carbon-steel rod handle speeds of 30-800 mm/s. Note that this specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

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.

Provides 402 N of push to strip woven fabric from the loom beam, using the 410-450 mm adjustable window to sync exact material roll widths without moving the cylinder base.
Transfers heavy wooden pallets onto a packaging line, relying on the adjustable air cushion to decelerate the 450 mm stroke smoothly and prevent end-cover shock damage.
Ejects cured carbon-fiber panels from a heated mold, utilizing the 346 N pull force and rear stopper to guarantee the press fully retracts before the mold opens.
If you need less force, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N for heavier payloads. Choose this MBLCJ over the fixed-stroke MBLC when you need to fine-tune the travel limit, or over the bumper-only MBLJ when moving substantial mass at high speeds. Remember the rear adjuster is a travel stop, not a lock; it sets the end point but does not hold the load pneumatically. Mounting is limited to Basic, FA flange, or LB foot brackets (no SDB or back-cover options). For an exact replacement, match the 32 mm bore, 450 mm stroke, 40 mm adjust code, G1/8 port, PT thread, and confirm no magnet is required. At this 450 mm stroke, the 12 mm rod is highly susceptible to side-load bending; always use an external guide rail to prevent cylinder damage.
Quick checklist
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 operating pressure. It operates at speeds between 30-800 mm/s.
The rear adjuster physically limits the piston's travel, allowing you to trim up to 40 mm from the 450 mm stroke for a 410-450 mm window. The adjustable air cushion only controls the deceleration rate at the stroke ends. Neither feature locks or holds the load in place; you need live air or an external lock for position holding.
