The AirTAC Airtac SC40 Standard Cylinder SC40X650STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 650mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X650STC is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a 650 mm stroke, the 16 mm diameter rod provides robust linear actuation for medium-reach applications.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder to pivot during operation. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps.

The 650 mm stroke and trunnion pivot allow the cylinder to sweep across a conveyor line, diverting or sorting medium-weight packages with the 628 N push force.
Ideal for automated welding or assembly jigs where the cylinder body needs to swing into position. The magnetic piston confirms clamp engagement via a DMSG sensor.
Operates sliding gates on hoppers or chutes in dusty environments. The centre trunnion mount handles the arcing motion, while the 1130 N force at 0.9 MPa overcomes sticky material.
For higher force, step up to the SC50 (982 N push at 0.5 MPa); for a smaller footprint, the SC32 offers 402 N. At 650 mm stroke, ensure the rod is protected from side loads—consider an external guide rail to prevent rod bending and premature bearing wear. When replacing, match bore (40 mm), stroke (650 mm), PT port thread (PT1/4), TC centre trunnion mount, and the -S magnet option to maintain sensor compatibility.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes, the TC suffix indicates the centre trunnion is supplied together with the TCM1 trunnion mounting bracket (order code F-SC40TC). The bracket allows the cylinder body to pivot freely, which is essential for swinging or arcing loads.
