The AirTAC Airtac MBLCJ Adjustable Mini Cylinder MBLCJ40X500-10S is a genuine double-acting aluminum-barrel mini cylinder with a Ø40mm bore, a 500mm nominal stroke and a rear adjustable-stroke stopper — trim up to 10mm for a usable window of 490–500mm. Adjustable air cushion (both ends).
The AirTAC MBLCJ40X500-10S is a compact double-acting aluminum mini cylinder featuring a rear stroke adjuster and an adjustable air cushion at both ends. It delivers 628 N push and 528 N pull force at 0.5 MPa via a Ø16 mm hard-chrome plated carbon steel rod. The 10 mm rear trimmer creates a usable end-position window of 490 to 500 mm, allowing precise mechanical timing for long-travel tasks.
Unlike the fixed rubber bumper found on the base MBLJ, the screw-tunable air cushions on this unit decelerate heavy loads over a 500 mm run, protecting the end covers from impact. The riveted rolling-packed aluminum barrel retains a heterogeneous two-way grease piston seal. A built-in magnet (-S) enables position detection, while the overall length extends by the adjustment dimension. Note that the rear stopper sets travel limits but does not lock the load.

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 500 mm loom reed motion, using the adjustable cushion to smoothly arrest the 628 N force without jarring the warp yarns at the end of travel.
Trims the final 10 mm of the 500 mm stroke to perfectly align the strapping head, relying on the G1/4 port for rapid actuation during high-cycle packaging.
Shifts heavy tool carriages along the 500 mm path, using the DMSG electronic sensor to confirm retraction and the tunable cushion to protect the chassis.
For 500 mm moves at 628 N push (0.5 MPa), this 40 mm bore is a strong fit. If you need less force, stepping down to the 32 mm bore yields 402 N push; stepping up to the 50 mm bore provides 981 N push. Choose this MBLCJ over an MBLJ when your moving mass requires tunable end-of-stroke deceleration rather than a fixed bumper, or over an MBLC if you need the rear travel adjuster. Because the 500 mm stroke is at the maximum standard limit for this bore, external guidance is highly recommended to prevent rod bending under side loads. The rear adjuster is a travel stop, not a lock, so an external holding device is required if the rod must hold position without live air. Mounting is limited to Basic, FA, or LB styles with no SDB or back-cover options. The exact replacement match is a 40 mm bore, 500 mm stroke, 10 mm adjust code, G1/4 PT port, and an integrated magnet.
Quick checklist
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa the push force is 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa operating pressure.
The 10 mm rear adjuster is a mechanical travel stop that trims your usable stroke window to 490-500 mm. The adjustable air cushion is a separate screw that regulates exhaust flow to decelerate the piston near the end covers. Neither feature locks the load in place.
