About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100SU
The AirTAC MBLC63X100SU is a double-acting, single-rod aluminum mini cylinder featuring a 63 mm bore and 100 mm stroke. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it well-suited for moving heavier payloads through a compact 100 mm travel distance. A defining feature of this SKU is the screw-adjustable pneumatic cushion at both stroke ends, which allows you to dial in end-of-stroke deceleration to match your specific load and speed, absorbing kinetic energy to protect the end covers.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant provides tunable shock absorption for high-frequency or fast-cycling equipment. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight machinery envelopes, while the 20 µm hard-chrome plating on the carbon-steel rod resists wear. The 'U' designates a rigid flat-end back cover for straightforward inline mounting, and the built-in magnet (-S) supports position detection via CMSG, DMSG, or EMSG sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100SU Is Used
Injection Molding Ejection
Provides 1558 N of push at 0.5 MPa to knock out dense plastic parts from injection molds, using the adjustable cushion to silently decelerate the 100 mm stroke and prevent mold plate damage.
Press Brake Tooling
Actuates heavy lower dies in a 63 mm bore press brake fixture, relying on the tunable air cushion to absorb the 1457 N pull force impact during rapid retraction cycles.
Pallet Diverting
Drives a rigid diverting arm on a packaging conveyor, using the flat-end U cover for inline mounting and the built-in magnet to confirm extend and retract positions at high speed.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100SU the Right Cylinder?
Stepping down in bore size, the 50 mm neighbor provides 981 N of push force at 0.5 MPa, which is better for lighter loads if you need to save space. Stepping up is not possible as 63 mm is the largest standard bore in this series, offering the maximum 1558 N at 0.5 MPa (318 kgf theoretical max at 1.0 MPa). Choose this MBLC version over the fixed-bumper MBL when your application cycles quickly or moves a substantial mass that would prematurely wear out a rubber stopper.
Because the 100 mm stroke is relatively short for this large bore, rod bending side-loads are minimal, but the 16 mm rod still has low side-load tolerance; avoid hanging heavy offset loads directly off the rod. Note that the adjustable air cushion only decelerates the piston near the end of travel—it is not a brake. If you need to hold position vertically when air is removed or the valve centers, you must add an external rod lock or pilot-operated check valve. This replacement SKU features a G1/4 port, PT thread form, U flat-end back cover, and an integrated magnet for sensor switching.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100SU FAQ
This 63 mm bore cylinder delivers a push force of 1558 N and a pull force of 1457 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N. The theoretical maximum force is 318 kgf when operated at the maximum rated pressure of 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near the stroke ends, reducing impact noise on fast moves. It is not a load-holding brake. The -S code means a built-in magnet is fitted for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic solid-state) sensor switches.
