The AirTAC Airtac SC40 Standard Cylinder SC40X33 is a genuine double-acting standard air cylinder with a Ø40mm bore and 33mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X33 is a compact double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 33 mm stroke suit short linear movements in clamping, pressing, and sorting stations.
Built on the proven SC tie-rod platform, this model features a 16 mm diameter piston rod with M12x1.25 male threads and a 21 mm adjustable air cushion at each end. The body length A is 142 mm, giving a total extended length of approximately 175 mm—ideal for space-constrained machine designs.

The 33 mm stroke and 628 N force at 0.5 MPa make this cylinder ideal for pneumatic clamping fixtures in CNC machining and assembly jigs.
Use the SC40X33 as a compact part stop or diverter gate on light-duty conveyor lines, where a fast, repeatable 33 mm throw is required.
With 1130 N available at 0.9 MPa, this cylinder handles small press-fit and staking operations in automated assembly cells.
For applications needing more force, step up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If a lighter, faster actuator is preferred, the 32 mm bore SC32 delivers 402 N at the same pressure. This 33 mm stroke is non-standard; verify lead time with your AirTAC distributor.
When replacing an existing cylinder, match five key points: bore (40 mm), stroke (33 mm), port thread (PT1/4), mounting accessory (basic, no bracket), and magnet option (none). The SC40 is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Replace only with another AirTAC SC40 of matching stroke, port thread, and mounting.
