Airtac BSAI Locking Clamp Cylinder BSAI125X250S
A cropped merino wool cardigan taken up a notch, thanks to the flecks of metallic thread throughout. We love it even more paired with the matching sweater-pants.
1. A derivative series combining standard cylinders with integrated locking mechanisms;
2. Capability of position locking and braking at any intermediate stroke position;
3. Optimized locking design ensuring consistent holding force regardless of piston movement direction.

Heavy-duty locking cylinder featuring fail-safe mechanical braking system that activates automatically during power/pneumatic failure. The dual-piston brake mechanism provides 1.5× standard holding force compared to conventional designs. Requires 0.3MPa minimum air pressure for brake release. Includes anti-rotation guide for precise linear motion.
- Vertical load holding in automated material handling systems
- Emergency position locking in CNC machine tool changers
- Overhead conveyor safety brakes
- Press machine mid-stroke positioning
- Robotic welding fixture position retention
- Brake requires 0.15s minimum air supply duration for full release
- Maximum side load capacity: 850N at mid-stroke
- Lubrication: ISO VG32 hydraulic oil recommended (drip feed 1-2 drops/min)
- Mounting orientation: Any (vertical preferred for optimal brake wear)
- Maintenance cycle: 2,000km travel or 12 months (whichever first)
Critical: Brake system requires run-in procedure -
Perform 50 full-stroke cycles at 0.3MPa before full-load operation.
