The AirTAC AirTAC MBL63X350SU Mini Cylinder | 63mm Bore 350mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 350mm 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 MBL63X350SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 1558 N push force at 0.5 MPa, making this 63 mm bore variant the highest thrust class in the MBL family. The 350 mm stroke suits extended routing or actuation tasks that demand significant reach without the bulk of an ISO 15552 profile body.
This SKU includes a built-in magnet (-S) for direct mounting of AirTAC CMSG reed or DMSG and EMSG electronic sensor switches to detect rod position. The U suffix denotes a rigid flat-end back cover for straightforward fixed mounting. Internally, the riveted rolling-packed barrel crimps the covers to the tube for a lightweight, non-rebuildable body, while a heterogeneous two-way piston seal retains grease for long service life. The carbon steel rod features 20 um hard-chrome plating for wear resistance.

Provides the 1558 N push force needed to shove heavy loaded pallets off a transfer line at the end of a packaging conveyor.
Uses the 350 mm stroke to reach deep into a plastic injection molding machine and knock out finished parts without risking interference.
Swings a sorting arm to route heavy totes between logistics chutes, relying on the DMSG electronic sensor to confirm the extended position.
As the largest bore in the MBL range, stepping down means choosing the 50 mm bore, which yields 981 N push force at 0.5 MPa for lighter duties. If 318 kgf of maximum theoretical force is insufficient, you must move out of the mini round family entirely to a larger profile cylinder. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning to handle faster cycling or heavier masses, select the MBLC variant.
A 350 mm stroke on a 16 mm rod creates a high slenderness ratio, meaning the rod bearing is highly susceptible to bending under side loads. You must guide the load externally or use a pivot mounting accessory. Note that this cylinder does not hold its load if air pressure drops; the rod will drift. Use an external rod lock or pilot-operated check valve for fail-safe position holding. Replacement requires matching the 63 mm bore, 350 mm stroke, G1/4 port, PT thread, U flat-end cover, and -S magnet.
Quick checklist
At 0.5 MPa it provides 1558 N push and 1457 N pull force. At 0.7 MPa the push force is 2181 N, with a maximum theoretical force of 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper on the end caps to soften impact, not an adjustable cushion screw. If your application requires adjustable end-of-stroke air cushioning for heavier loads, select the MBLC variant.
