Sourcing route & inquiry details
BSCD is the double-rod locking member of the BSC tie-rod family; confirm both rod ends and the separate locking circuit. Match bore, listed stroke, magnet and supported mounting, then send the lock circuit and actual static load for quotation and holding confirmation. Static holding data does not approve dynamic braking or safety use.

AirTAC BSCD specification official reference
Helpful for Model Matching:
- Complete model or original label
- Listed bore/stroke, magnet and supported mounting
- Lock/release circuit and actual static load/holding direction
- Cylinder ports versus G1/8 locking port; rod and installed clearance
- Accessory/sensor codes, quantity and destination
- Match single versus double rod; BSCD unspecified dimensions follow BSC.
- Confirm lock G1/8 independent of main-cylinder PT/G port.
- Check lock circuit, static load and exact mounting/accessory pairing.
- Use bore-specific standard stroke and speed; no dynamic brake inference.
Catalogue Technical Specifications
| Identity / lock | BSC is an SC tie-rod double-acting cylinder with added locking structure. BSCD is its double-rod member, with both rod ends requiring clearance. The source says it can lock at random positions within stroke and lock state is unrelated to piston movement direction; it does not publish safety certification or dynamic brake capacity. |
| Standard strokes / 32 boundary | 32 standard row explicitly lists 25/50/75/80/100/125/150/160/175/200/250/300/350/400/450/500 mm, though max column says 700. 600/700 for bore 32 require confirmation. 40 adds 600/700/800; 50/63/80/100/125 add 600/700/800/900/1000. Non-standard strokes require consultation. |
| Pressure / unlock | Cylinder operating pressure is 0.15–0.7 MPa; unlocking requires 0.3–0.7 MPa; proof pressure is 1.5 MPa. BSAI unlocking limits do not apply to BSC; proof pressure is not an operating pressure. Confirm actual locking/release pneumatic circuit and load state. |
| Cylinder / lock ports | Cylinder ports: 32 1/8; 40/50 1/4; 63/80 3/8; 100/125 1/2. Cylinder thread blank PT or G, no NPT T. Locking equipment port is fixed G1/8 across bores, distinct from main-cylinder thread/size. |
| Static holding force | 32/40/50/63/80/100/125 static holding force 600/900/1400/2200/3600/5500/8600 N. This is not cylinder thrust, TC bracket holding force, dynamic stopping force, payload kg or a certified fail-safe function. |
| Speed / temperature / air | 32–100 speed 30–800 mm/s; 125 speed 30–500 mm/s. Air through 40 μm filter; −20 to 70°C. Lubrication requirements for BSC need separate confirmation; the generic SC statement does not apply. |
| Cushion / tolerance | Variable cushion stroke: 32/40/50/63 21 mm; 80 28 mm; 100 29 mm; 125 28 mm. Stroke tolerance: 0–250 +1.0/0 mm, 251–1000 +1.5/0, 1001–1500 +2.0/0. The tolerance row does not make 1001–1500 standard strokes. |
| Magnet / accessories | Blank without magnet or S with magnet. Sensors are referred to printed page 409, not present in this source. The sensor model and mounting compatibility require separate confirmation. CR, FTC, high-temperature/seal or rod-knuckle suffixes are not published complete-cylinder ordering options here. |
| Dimensions / material | BSCD total A+2×stroke, opposite rod dimensions AF+stroke/DA+stroke; unspecified dimensions follow BSC. Magnet dimensions same as non-magnet. BSCD drawing table only repeats selected dimensions. Lock module material drawing is based on a certain bore, not universal BOM. |
| Static locking / release sequence | The lock may engage only after the piston stops; it cannot brake the moving rod. Release only when piston-side forces are balanced or the air supply is stopped, otherwise sudden motion can occur. Published example circuits are separate for horizontal/vertical installation and show >=0.5 s and 0–0.5 s sequencing intervals; confirm the complete actual circuit and load rather than promise safety certification. |

Quick check
Can static holding force be used as dynamic braking capacity?
No dynamic stopping or safety certification is published here. Confirm the actual lock circuit, motion state and static load before selecting the assembly.
Can BSC 32 be automatically matched at 600 or 700 mm?
The maximum column says 700, but its explicit standard list stops at 500. Send the original requirement for confirmation. Do not replace this row with the SC standard-stroke list.
