The AirTAC Airtac SC40 Standard Cylinder SC40X190 is a genuine double-acting standard air cylinder with a Ø40mm bore and 190mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X190 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 190 mm stroke. At 0.5 MPa it produces 628 N extending force and 528 N retracting force, rising to 1130 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 16 mm diameter piston rod with M12x1.25 male thread and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the TPU/NBR seals suit ambient temperatures from -20 to +70 °C. Body length A is 142 mm, giving a total extended length of approximately 332 mm.

The 628 N push force at standard shop air is ideal for diverting light cartons or plastic totes on a packaging conveyor, where the 190 mm stroke gives enough reach across a single lane.
With 1130 N available at 0.9 MPa, this cylinder provides consistent clamping pressure for CNC jigs and assembly fixtures, holding workpieces securely during drilling or bonding operations.
The 16 mm rod and 190 mm stroke suit light press-fit tasks such as inserting bearings or bushings into housings, where controlled force and smooth cushioning protect the parts.
Choose the SC40X190 when your application needs roughly 600–1100 N of push force. If you require more force, the SC50 series steps up to 982 N at 0.5 MPa; for a lighter, more compact solution the SC32 delivers 402 N. Always match replacement cylinders on all five key points: 40 mm bore, 190 mm stroke, PT1/4 port thread, basic (no accessory) mounting, and no magnet.
At 190 mm stroke the rod is well supported within the standard range, but any side load should be carried by an external linear guide rather than the rod bearing alone.
Quick checklist
At 0.5 MPa the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa the extending force reaches 1130 N. The theoretical force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder of the same bore and stroke, so the mounting dimensions are not interchangeable. Only replace another AirTAC SC (or equivalent tie-rod cylinder) matching bore, stroke, port thread, mounting, and magnet option.
