About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X175-10S
The AirTAC MBLCJ63X175-10S is a compact double-acting aluminum mini cylinder engineered for heavy-duty positioning, delivering 1558 N of push force at 0.5 MPa. It features a rear travel stopper that allows you to trim the stroke by up to 10 mm, creating a usable extension window of 165 to 175 mm. Unlike the fixed rubber bumper found on the MBLJ series, this model incorporates a screw-tunable adjustable air cushion at both ends to smoothly decelerate heavy loads before contact. The built-in magnet (-S) enables precise rod-position detection.
Because the 63 mm bore utilizes a Ø16 mm carbon-steel rod with 20 um hard-chrome plating, it resists scoring under high thrust, though the 175 mm extension necessitates an external guide to prevent rod bending. The riveted rolling-packed aluminum barrel and heterogeneous two-way grease-retaining piston seal ensure consistent friction throughout the 30-800 mm/s speed range. Remember that the rear stopper sets the travel end and the cushion only decelerates; neither component acts as a mechanical lock to hold a load in place without live air pressure.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X175-10S Is Used
Injection Mold Ejection
Provides the 1558 N push force required to eject dense plastic parts from mold cavities, using the dual air cushions to prevent harsh impacts at the 175 mm stroke end.
Pallet Diverting Arm
Uses the 10 mm rear stroke adjustment to dial in the exact stopping distance for a diverting arm on a heavy-duty packaging conveyor, ensuring precise pallet alignment.
Press Brake Gauging
Leverages the built-in magnet with a DMSG electronic sensor to confirm rod position for sheet metal back-gauging, handling the heavy moving mass of the gauge assembly.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ63X175-10S the Right Cylinder?
Select this 63 mm bore when your application requires moving substantial mass, as it yields 1558 N push and 1457 N pull at 0.5 MPa. If you need less force to save space and air consumption, step down to the 50 mm bore, which provides 981 N of push force. If you require even greater thrust, the 63 mm is the largest available size in this mini round-body family. Choose the MBLCJ over the MBLJ when your moving mass is too high for a fixed rubber bumper, or over the MBLC when you need to fine-tune the end-of-stroke position via the 10 mm rear adjuster.
For a direct replacement, match the 63 mm bore, 175 mm stroke, 10 mm adjust code, G1/4 port, PT thread, and the -S magnet. Mounting is limited to Basic, FA (flange), or LB (foot); there is no SDB pivot or back-cover option available. At 175 mm of stroke, the small 8-16 mm rod diameter is susceptible to side-loading, so an external guide rail must be used to prevent premature seal failure and rod bending.
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 MBLCJ63X175-10S FAQ
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
The 10 mm rear adjuster is a mechanical travel stop that physically sets the end-of-stroke position between 165 and 175 mm. The adjustable air cushion is a screw-tunable valve that regulates exhaust flow to decelerate the piston near the end covers. Neither feature locks or holds the load in place without continuous air pressure.
