| Sensor selection |
Magnetic sensing requires an S cylinder; a sensor adds no magnet |
| Estimated cylinder weight |
21471 g; engineering reference, not measured shipping weight |
Engineering weight estimate using the same-bore SC catalog as a baseline plus an equivalent extra-rod allowance with representative steel density. The adjustment mechanism, changed covers and internal details are not separately mass-resolved. Mounts, rod-end joints, sensors, fittings and packaging are excluded. This is not an official SCJ net mass or a measured shipping weight; no error bound is established. Use the actual weighed assembly for handling and shipping.
Confirm actual travel, stop setting and end positions; the adjustment code alone does not specify usable travel. Check cushioning at the setting; strokes shorter than 33 mm cannot provide full nominal cushion travel.
Features and Operation
SCJ provides double-acting through-rod motion and stroke adjustment. Family references: aluminium-alloy barrel and covers with tie rods, compact bidirectional grease-retaining piston seal, adjustable pneumatic cushioning.
Confirm the ordered cylinder for the 150 °C special-seal feature; this NBR configuration remains −20 to 70 °C.
External and Mounting Dimensions
Dimensions: mm except threads; magnetic/nonmagnetic basic dimensions are equal. Drawing lengths do not guarantee the installed/moving envelope. Check clearance for both rods, adjustment, mounts, rod joints, fittings and sensors.

Verify genuine SCJ seal kits, wear rings, guide bushings, nuts, covers and adjustment parts by exact model, seal and production revision. Drawing numbers and bore size are not service ordering codes. This nonmagnetic configuration has no built-in magnet.
Force and Circuit Selection
| Parameter |
Value |
| Ideal effective area, both directions |
30159.29 mm² = π / 4 × (200² − 40²) |
| Calculated force at 0.5 MPa, both directions |
15079.64 N |
| Force calculation |
Force (N) = annular pressure area (mm²) × pressure (MPa), before friction, backpressure and dynamic losses |
| Load-ratio guidance |
Up to 0.7 at static/low speed, 0.5 at 50–500 mm/s and 0.3 above 500 mm/s, subject to cylinder speed limits; not guaranteed payload/structural safety factors |
Equal-diameter through-rod calculation. Size for annular area, load, adjusted travel, line losses, valve flow and exhaust backpressure; bore alone does not determine speed/payload.
Installation and Maintenance
Qualified staff must select, install and service the system. Guard both moving rod ends and secure the cylinder, loads and attachments. Before service or adjustment, isolate air and electricity, vent pressure and secure motion. Design safe responses to air/power loss, emergency stops and restart.
Check protection from corrosive gas, chemicals, solvents, salt, water or steam, explosive atmospheres, vibration, radiant heat and sunlight. Protect sliding surfaces from damage, dust, humidity, splashes, oil and coolant. Prevent condensate freezing; external magnetic fields may disturb magnetic sensing.
Use clean, dry, purified compressed air. Remove water, particles, oxidized oil, tar and carbon; filter to 40 µm or finer. Confirm suitability for other fluids and synthetic-oil contaminants. Excessively dry air may shorten life unless the component is designed for it.
Factory lubrication normally needs no added oil. Once oil is introduced, continue additive-free ISO-VG32 turbine oil; incompatible oil may swell seals. The guide gives oil mist ≤25 mg/m³ and 0.5–5 drops per 1000 L. Size the lubricator for actual flow and avoid excess oil.
Blow pipes clean; start sealing tape 1.5–2 threads back to keep fragments out. Use suitable flame-resistant or metal tube near hot spatter. Check each tube’s pressure, temperature, OD, ID and bend radius; generic nylon/PU advice cannot override its rating.
PT3/4 piping torque: 28–30 N·m with the specified mating connection; not a G/NPT installation or sensor-adjustment torque.
Use speed controls at both working ports; start closed and open slowly. Meter-out commonly stabilizes motion and reduces startup runout. Adjust cushioning gradually for the load and speed, avoiding impact, rebound or forcing its screw. High mass or speed may need engineered deceleration or an external absorber.
Air compressibility and leakage prevent assuming precise prolonged intermediate stopping with a closed-center valve or precise cylinder synchronization. Verify the adjusted travel, mechanical stop setting, available cushioning, air consumption and clearances for the actual application.
Align rod and load motion and provide independent guidance against side load, bending and torque. Check long-rod buckling, sag and vibration; support long spans and limit unsupported lever arms. Use a suitable TC pivot arrangement for swinging motion rather than forcing a rigid LB mount. Check bracket loads and flange orientation.
During long storage, operate periodically and prevent corrosion, following the air-quality and lubrication requirements.

Connection and Upstream Options
| Complete ordering code |
Separately installed upstream filter/regulator |
| GAFR50020S |
two female PT3/4 ports; PC bowl, 108 cc; round gauge in MPa/psi |
| GAFR600C20S |
two female PT3/4 ports; Metal bowl, 205 cc; round gauge in MPa/psi |
Select separate male PT3/4 fittings for both cylinder working ports, with tube OD/ID, flow capacity, seal and clearance matched to the installation. PT, G and NPT are not interchangeable. The M36×2.0 rod thread is not an air port.
The filter/regulators below are separate upstream options, not cylinder-port fittings or an included kit. Connect their IN/OUT ports with correctly matched male fittings. Do not fit a smaller male connector directly into a larger port; any adapter must match both thread sizes, standards and genders without restricting required flow.
These complete ordering examples use compressed air, a 40 µm element, differential-pressure/manual drain, included bracket and round gauge, standard regulation and no reverse-flow valve. The 500 series uses a PC bowl; 600C uses a metal bowl. Other configurations require their own ordering codes.
Maximum inlet pressure 1 MPa; proof pressure 1.5 MPa is not operating pressure. Adjustment range 0.15–0.9 MPa; temperature −5–70 °C, non-freezing. Observe flow/pressure loss, IN/OUT direction, condensate drainage, bowl environment and every downstream component limit. These are not vacuum regulators.
Size the valve, tubing and both endpoint connections for the required load, stroke, speed and pressure loss. Do not use a smaller-bore selection table as a guaranteed large-cylinder speed rating. Meter-out controls must match the actual port and circuit; valve-exhaust silencers must match that valve’s exhaust ports. Do not place silencers or plugs on either active cylinder port.
Tube OD and ID must match the specified fittings; inch tubing is not interchangeable with nominal metric tubing. A 16 × 11 mm tube requires separately specified 16 mm endpoint fittings and controls. Select the complete connection path before ordering; the upstream unit alone does not specify a full pneumatic circuit.
SCJ has two working ports and equal-diameter rods. Size flow using its annular pressure area, actual load, adjusted travel, piping losses and exhaust backpressure; a general bore-based chart does not guarantee SCJ speed.
