QDK horizontal rotation zero axial rotation travel and arm mounting overview
Helpful for Model Matching:
| Identity / motion | Double-acting horizontal rotary clamp, bores 20/25/32/40. Rotation occurs in the horizontal plane, axial rotation stroke 0 mm; fixed clamping stroke 5 mm. Do not confuse the 5 mm clamp travel with rotation travel. |
| Direction / angle / repeatability | L left (anti-clockwise), R right (clockwise), in the illustrated downward/retraction clamping sequence. Nominal 90° rotation; overview direction drawing labels 90°±3°, while specification repeatability is ±2°. These are different published fields, not interchangeable tolerances; confirm actual fixture angle requirement. |
| Working / proof / medium | Air filtered 40 μm; operating 0.15–1.0 MPa; proof 1.5 MPa is not working. −20 to +70°C; bumper cushion. No universal maximum speed published: arm inertia limits speed. |
| Ordering / magnet / cover | QDK[L/R][20/25/32/40]×5S[U][G only 40]. S with magnet is the only published magnet choice. Front cover blank boss, U flush; these ordinary mounting choices remain family fields. Sensor detail referenced to printed page362, exact sensor not established here. |
| Ports / thread | 20/25/32 M5×0.8 metric; 40 1/8. Published pipe thread blank PT or G. Small metric ports use no pipe-thread suffix. No NPT/T or separate thread on M5 inferred. |
| Published retraction clamp force | IN(Clamp) force table at 0.5 MPa for20/25/32/40: 80.4/168.9/319.5/497.2 N. Source pressure-force table, not full-bore pushing force, not a universal arm-tip force/holding guarantee. Rod sizes12/12/12/16 mm. Values include source-specific pressure offsets; do not replace them with simple bore-area×pressure calculations. |
| Arm length / pressure | Use actual arm length and working pressure within Graph1 operating range. Source 80 mm arm example: QDK20/25 pressure below 0.45 MPa, QDK32/40 below 0.55 MPa. General operating1.0 MPa does not authorize a long arm at that pressure. |
| Inertia / speed | Graph2 relates arm moment of inertia and cylinder average speed. Example at 10⁻³ kg·m²: QDK20/25 below 65.5 mm/s, 32/40 below 120 mm/s. Source says average piston speed=highest speed/1.6. These example speeds apply to the stated inertia only; exact arm inertia and speed need confirmation. |
| Mounting / arms / drawings | Boss and flush front end caps use their own complete dimensional tables. Compare mounting holes, rod/arm interface and installation envelope. Clamp arm is available by consultation; do not promise an included arm. Use spanner and Allen wrench to fit/remove rocker; do not hold body or cylinder may be damaged. |
| Materials / installation | Material table based on a certain bore; piston listed aluminium alloy for 40 and brass for others. Exact-bore materials require confirmation. Remove pipe contaminants, protect against freezing and corrosion, adjust speed with one-way flow control. No air-loss self-locking or retained-load function is established by this source. |

No. Rotation is horizontal with zero axial rotation stroke. The separate retraction clamp stroke is5 mm after90° rotation. Compare fixture clearance and the complete clamping sequence.
The general operating range does not override arm bending and inertia charts. For an 80mm arm the source example requires below 0.45 MPa (20/25) or0.55 MPa (32/40). Send actual arm geometry, mass, inertia, pressure and speed for confirmation.
