The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X110-100 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø63mm bore, 110mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X110-100 is a double-acting, single-rod pneumatic cylinder that puts a 100 mm field-adjustable stroke range at your fingertips. With a 63 mm bore delivering 1559 N of push force at 0.5 MPa, it handles mid-range clamping and positioning tasks where the exact end-of-stroke position needs to be dialled in during commissioning or after a format change. The rear-cap adjusting screw lets you shorten the nominal 110 mm stroke by up to 100 mm without dismounting the cylinder or adding external hard stops.
The 20 mm diameter piston rod and 28 mm air cushion provide smooth deceleration, while the PT1/4 port keeps plumbing simple. At the full 0.9 MPa operating pressure, push force reaches 2805 N, giving a comfortable margin for dynamic loads. The tie-rod construction and 197 mm body length A(SCJ) make it a direct, field-tuneable replacement for fixed-stroke setups that need frequent end-point adjustment.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Dial in the exact stop position during machine setup without machining new hard stops. The 100 mm adjustment range lets technicians quickly compensate for tooling variations or stack-up tolerances on assembly fixtures.
Adjust the stroke end to match different product sizes on a packaging or sorting line. The rear screw allows operators to switch between formats in seconds, reducing downtime compared to swapping out fixed-stroke cylinders.
Take up mechanical wear in gripper jaws, press tools, or brake pads over time. The adjustable stroke end acts as a serviceable limit stop, extending the useful life of the tooling without replacing the actuator.
Choose the SCJ63X110-100 when your machine needs a stroke that can be shortened on the fly by up to 100 mm—ideal for commissioning trials or wear take-up. If 1559 N of push force at 0.5 MPa is more than you need, stepping down to a 50 mm bore SCJ50 series cuts push force to 982 N. When the application demands a fixed, non-adjustable stroke, the standard SC63 cylinder is a simpler alternative. For a direct replacement, match the 63 mm bore, 110 mm nominal stroke, 100 mm adjust range, PT port thread, and basic mounting style. Should your motion require guided support, consider adding an external guide rail or switching to a guided cylinder assembly.
Adjustable-stroke checklist
Push force is 1559 N at 0.5 MPa and 2805 N at 0.9 MPa. Pull force is 1402 N at 0.5 MPa and 2523 N at 0.9 MPa. The pull force is lower because the 20 mm rod reduces the effective piston area on the return stroke.
Yes, provided the mounting and porting match. The SCJ63X110-100 has the same 63 mm bore and PT1/4 ports as the SC63 series but adds a rear adjusting screw that shortens the stroke by up to 100 mm. The body length A(SCJ) is 197 mm, which is slightly longer than the fixed-stroke SC version to accommodate the adjustment mechanism.
