Helpful for Model Matching:
| Identity and action | TWQ fixed-height double acting; TTQ single-acting retract. TTQ air enters to retract and compress the spring; on air loss, spring returns the rod to the extended position. This is not a spring-retract cylinder. |
| Bore and stroke | Bores20/25/32mm: standard strokes10/15/20mm. Bores40/50mm:20/25/30mm. Stroke tolerance +1/0mm. Unlisted strokes need label/drawing confirmation, not automatic standard matching. |
| Stopper head and self-lock | C round rod, B flat rod and R roller available20–50mm. K lever roller with adjustable hydraulic damper only32/40/50mm. F optional self-lock only on K; blank no self-lock. Lever self-lock prevents bounce-back after impact; it is not a safety or fail-safe claim. |
| Operating pressure | TWQ double acting0.15–1.0MPa. TTQ Ø20:0.25–1.0MPa; other TTQ bores0.2–1.0MPa. Proof1.5MPa is not the operating limit. Confirm conveyor side load against pressure, not proof pressure. |
| Working conditions | Filtered air40μm or finer; −20 to70°C; no lubrication required; bumper cushioning. K has a separate adjustable hydraulic impact damper. Keep port, stroke and head clearances from the actual installation drawing. |
| Ports and thread code | Ø20/25 actual port M5×0.8; Ø32/40/50 PT1/8. Only blank PT ordering field is published; no G/NPT code inferred. Actual M5 is metric despite the blank ordering field. |
| Magnet and sensor | S magnet; blank no magnet. Body has sensor grooves on four sides; sensor selection referenced to catalogue409 is not transcribed here. A magnetic cylinder does not automatically include sensor model/cable or confirm control-system compatibility. |
| Load-curve scope | Use separate round/flat/roller and internally damped lever mass-versus-impact-speed curves: mass m in kg, speed V in m/min. Side-load chart uses W in N and P in MPa and applies to round/flat/roller forms. The charts do not publish one universal payload/energy rating or automatic machine approval. |
| Mounting and head envelope | Fixed installation height, through-hole and two-end tapped mounting. Compare own C/B/R/K dimensions, table fixing holes and extended/retracted head height. Ø32/40 lever installation from below a plate follows remove-head/body-install/reassemble-head sequence; do not apply that specific procedure to every bore or head. |
| Damper replacement | K Ø32/40/50 replacement code ASJ1408 is published. Source says this unit can operate under pressure and differs from ordinary oil-pressure dampers; do not substitute a generic damper solely by outer size. Confirm exact head/damper assembly, adjustment and replacement scope. |

No. Send head type, moving mass, impact speed, side load, operating pressure and installed height/drawing. C/B/R and damped K use different source curves; self-lock and spring return have their own functions. Match the actual assembly before quotation.
