The AirTAC Airtac SC32 Standard Cylinder SC32X45H is a genuine double-acting standard air cylinder with a Ø32mm bore and 45mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X45H is a compact double-acting tie-rod cylinder with a 32 mm bore and 45 mm stroke, fitted with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. At 0.5 MPa it delivers 402 N push force and 345 N pull force, making it suitable for light clamping, sorting, and ejector tasks in hot zones.
Its 12 mm diameter piston rod and M10x1.25 rod thread provide adequate rigidity for short-stroke inline loads. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end of travel, while the PT1/8 port threads ensure straightforward pneumatic connection. Body length A is 140 mm, giving a compact total extended length of approximately 185 mm.

Viton seals allow the SC32X45H to operate continuously in ambient temperatures up to 150 °C, ideal for actuating dampers, diverters, or clamps near ovens, autoclaves, and foundry equipment.
With 402 N push force and a 45 mm stroke, this cylinder reliably ejects small plastic or metal components from hot moulds and die-casting tools without seal degradation.
FKM seals resist steam and cleaning agents. Use the SC32X45H in autoclave door locks, tray pushers, and valve actuators where frequent high-temperature sterilisation cycles occur.
Choose the SC32X45H when you need a heat-tolerant cylinder with a push force around 402 N at 0.5 MPa. If your load requires more force, step up to the SC40 series (628 N push at 0.5 MPa). For side-load applications or strokes beyond 300 mm, add an external guide or switch to a guided cylinder to protect the rod bearing.
For drop-in replacement, match five points: 32 mm bore, 45 mm stroke, PT port thread, Viton seal (H suffix), and basic mounting. This model does not include a magnet; if sensor feedback is needed, order the -S variant.
Quick checklist
At 0.5 MPa the push force is 402 N and pull force is 345 N. At 0.7 MPa push reaches 563 N, and at the maximum operating pressure of 0.9 MPa it delivers 724 N push force. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes, provided the original is a tie-rod cylinder with 32 mm bore, 45 mm stroke, PT1/8 ports, and basic mounting. The SC32X45H uses Viton seals for 0–150 °C; if your application runs below 70 °C, the standard TPU-seal SC32X45 is also compatible. Always verify rod thread (M10x1.25) and cushion length (21 mm) match your setup.
