About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-30S
The AirTAC MBLCJ50X500-30S is a double-acting, single-rod aluminum mini cylinder engineered for compact spaces. It features a rear adjustable stroke stopper allowing you to trim up to 30 mm of travel, creating a usable end-position window of 470 to 500 mm. Driven by a Ø16 mm hard-chrome plated carbon-steel rod, it delivers 981 N of push force and 881 N of pull force at 0.5 MPa. This 500 mm stroke is ideal for long-traverse material transfer or large robotic gripper actuation.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this MBLCJ variant incorporates a screw-tunable adjustable air cushion at both ends. This allows you to precisely dial in end-of-stroke deceleration for heavier moving loads, protecting the end covers from impact damage. The riveted rolling-packed barrel and grease-retaining piston seal ensure long-term lubrication. Remember that the rear stopper sets the travel end and the cushion only decelerates; neither component mechanically locks or holds the load in place without live air pressure.

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.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-30S Is Used
Long-Traverse Pallet Transfer
Drives 500 mm push strokes to shuttle heavy pallets between CNC machining centers, using the 981 N force and tunable cushion to stop 470 kg loads smoothly without slamming.
Large Robotic Gripper Actuation
Actuates wide-jaw grippers handling bulky cast parts, relying on the 470-500 mm adjustable window to precisely set the open position and prevent over-travel.
Textile Roll Ejection
Ejects heavy fabric or paper rolls from winding machines, using the dual-end adjustable air cushion to decelerate the 1374 N push force at 0.7 MPa before impact.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ50X500-30S the Right Cylinder?
When sizing this 50 mm bore cylinder, stepping down to the 40 mm bore yields 628 N of push force at 0.5 MPa, whereas stepping up to the 63 mm bore provides 1558 N. Choose the MBLCJ over the MBLJ when your application speed requires tunable pneumatic deceleration rather than a fixed bumper, or over the MBLC if you need to fine-tune the end position within that 470-500 mm window. Because the 500 mm stroke approaches the maximum standard limit for this bore, the small 16 mm rod is highly susceptible to side-load bending; always use an external guide rail to prevent cylinder damage. Mounting is limited to Basic, FA flange, or LB foot brackets, as no back-cover or SDB pivot options exist for this series. For a direct replacement, match the 50 mm bore, 500 mm stroke, 30 mm adjust code, G1/4 port, PT thread, and the built-in -S magnet.
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 MBLCJ50X500-30S FAQ
This 50 mm bore cylinder delivers 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical output of 200 kgf at 1.0 MPa.
The -S suffix indicates a built-in magnet compatible with AirTAC CMSG reed switches and DMSG or EMSG solid-state electronic sensors for position detection. The 30 mm adjustable stroke lets you set the rear travel stop within a 470-500 mm window, but this adjuster is a travel stop, not a load lock.
