The AirTAC AirTAC MBL63X250SCA Mini Cylinder | 63mm Bore 250mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 250mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL63X250SCA is a double-acting aluminum mini round cylinder engineered for substantial force in confined machinery envelopes. Delivering 1558 N of push force at 0.5 MPa and a maximum theoretical output of 318 kgf at 1.0 MPa, this 63 mm bore unit drives heavy actuators over a 250 mm stroke. The integrated -S magnet enables direct position feedback using AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensor switches, ensuring precise end-of-stroke signaling for automated sequences.
This SKU features a CA pivot back cover, allowing the cylinder body to swing freely on a pin to absorb angular misalignment and arcing loads during motion. Internally, a heterogeneous two-way piston seal retains grease for long-term friction reduction, while the Ø16 mm carbon-steel piston rod is protected by a 20 µm hard-chrome plating to resist scoring and atmospheric corrosion. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion, optimizing space within the riveted rolling-packed barrel.

Drives a robotic spot-welding gun head in a tight automotive cell, using the 1558 N push force to clamp panels securely while the CA pivot back cover accommodates minor angular arc movements.
Powers a heavy-duty diverting flap on a 250 mm stroke cycle for logistics sorting lines, where the built-in -S magnet triggers DMSG solid-state sensors to confirm gate open/close status.
Actuates a lifting probe in an electronics assembly tester, utilizing the 318 kgf maximum force capacity to raise populated circuit board trays while fitting within the compact riveted aluminum frame.
Select this 63 mm bore model when your application requires up to 1558 N of push force at 0.5 MPa, stepping up from the 50 mm bore variant (which provides 981 N push). If you need even greater thrust, the MBL series maxes out at this bore size, so exceeding 318 kgf theoretical force requires migrating to a larger ISO 15552 profile cylinder like the AirTAC SAI line. For end-position damping of heavier 250 mm stroke payloads, consider the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion to absorb kinetic energy safely.
Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly to the body for electronic positioning. Note that a standard MBL cannot hold a load if air pressure is lost or exhausted; the rod will drift, as the rubber bumper is not a locking mechanism. For vertical or suspended loads requiring fail-safe holding, install an external pilot-operated check valve or a dedicated rod lock. Additionally, the 250 mm stroke on an Ø16 mm rod necessitates side-load management: leverage the CA pivot back cover to prevent rod-bearing bending, or utilize an external guide rail to support the tooling.
Quick checklist
The 63 mm bore cylinder features a Ø16 mm carbon-steel rod with an M14x1.5 end thread and a G1/4 port. At 0.5 MPa it provides 1558 N push and 1457 N pull force; at 0.7 MPa it provides 2181 N push; the maximum theoretical force is 318 kgf at 1.0 MPa.
The CA back cover is a clevis-style pivot that allows the cylinder to swing on a mounting pin, making it ideal for arcing or angular load applications. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable cushion; if your 250 mm stroke generates excessive kinetic energy, upgrade to the MBLC variant for adjustable air cushioning.
