Description
The Airtec ZR-25-0400-2-B3 belongs to the ZR series and works double-acting with a 25 mm bore over a 400 mm stroke. A toothed belt in the outer chamber connects the piston driver via a deflection pulley to the carriage, and the adjustable plain bearing guide is integrated in the carriage.
Option: brake at 3 with extended synchronisation shaft at 2. The brake on the shaft holds the position reached, with a static braking force of 380 N at 6 bar. It is designed as a holding brake and must not be applied while the carriage is moving. The synchronisation shaft allows several cylinders to be coupled and operated in synchronism.
Benefits
- Slip-free force transmission via the toothed belt to a shaft
- Toothed belt in the outer chamber keeps dirt away from the sealing band
- Longitudinal slot does not widen under pressure, as the outer chamber encloses it
- Guide integrated in the carriage: adjustable plain bearing guide
Applications
Long-stroke drives that must hold a position reached, for example approaching intermediate positions with a 3/2-way valve controlling the brake.
