Helpful for Model Matching:
- Full model code or label
- Bore, working stroke and separate adjustment
- Mounting and rod-end / port drawing
- Magnet, seal and temperature where published
- Lock position or valve voltage/port/motion where applicable
- Quantity and destination
- Confirm functional derivative and its own dimensions
- Confirm working stroke, adjustment and mounting
- Separate rod end, cylinder port and valve port
- Check lock/valve and large-bore trunnion conditions
Catalogue Technical Specifications
| Cylinder pressure / proof | Operating 0.15–1.0 MPa; proof 1.5 MPa. Proof is not continuous operating pressure. |
| Medium / temperature | 40 μm filtered air; −20–70°C; double acting; adjustable pneumatic cushion. |
| Speed | 32–125: 30–800 mm/s; 160/200: 30–500 mm/s. Apply only to the current variant bore range. |
| Cylinder ports | 32: 1/8; 40/50: 1/4; 63/80: 3/8; 100/125: 1/2; 160/200: 3/4. Blank PT / optional G; no NPT field. |
| Rod end | 32: M10×1.25; 40: M12×1.25; 50/63: M16×1.5; 80/100: M20×1.5; 125: M27×2; 160/200: M36×2. Separate from air port. |
| Magnet / switch | Blank without magnet; S with magnet; CMSE / DMSE switches separately selected. Magnetic and non-magnetic dimensions are the same. |
| Mounting accessories | CR must be used with CB, not alone. FTC / TC use TCM1 / TCM2. TC 160/200 is factory installed on the barrel; position cannot be adjusted arbitrarily and cannot be assumed to retrofit a cylinder ordered without TC. TCM1/2 positions for 160/200 cannot be adjusted arbitrarily. |
| Fit / force | ISO15552, originally ISO6431. Confirm installed dimensions, rod-end, load, side loads and cushion. ISO alone does not guarantee interchangeability. Thrust is N at specified pressure, not payload kg. |
| Stroke tolerance | 0–250: +1/0; 251–1000: +1.5/0; 1001–1500: +2/0 mm. No extrapolation above 1500 mm. |
| Bore / strokes | 40/50/63/80/100/125/160/200; no 32. Enumerated strokes follow SAI at each bore. Maximum standard 40: 1200, others: 1500 mm; maximum stroke 40–125: 1800, 160/200: 2000 mm. Unlisted strokes require confirmation. |
| Lock / code fields | SAILB back-cover lock; SAILF front-cover lock. Terminal-position lock, not arbitrary-position BSAI or a mid-stroke braking guarantee. Automatic/manual release. Mounting blank/LB/FA/FB/CA/CB/CR/FTC/TC; S magnet; G thread. No SAI rod A/B or seal H/N fields. |
| Lock cushion / other end | Lock end 40/50/63/80/100/125/160/200: 20/21/21/22.5/22.5/24/24/28 mm; opposite end: 27/30/30/36/36/40/40/50 mm. |
| Lock circuit boundaries | Release lock before installation/adjustment. Terminal stroke must be reached. Unpressurized ports may release lock and allow sudden rod motion; verify load support and circuit. Avoid fast exhaust on locking side, back-pressure and excessive cushion restriction; reset manual unlocking device after use. Follow full manufacturer commissioning instructions. |

Quick check
Which function and interfaces should I confirm?
SAILB rear-cover lock or SAILF front-cover lock, operating only at terminal stroke. Confirm lock position and pneumatic circuit. Send full code, label or installation drawing with quantity and destination for quotation. Compare this derivative with its own drawing before replacement; ISO alone does not guarantee fit.
