🌟 Core Advantages: Compact Design, Big Performance
The DSBC cylinder redefines space-efficient automation without compromising on power or durability. As the successor to the trusted DNC series, it adopts the ISO 15552 standard for seamless replacement and global compatibility, with a streamlined profile that fits tight installations where every millimeter counts .
Key Features & Technologies
- ISO 15552 Compliance: Standardized mounting, bore, rod, and thread dimensions for universal interchangeability; replaces legacy ISO 6431/DIN ISO 6431 models .
- Three Cushioning Options:
- P: Elastic end buffers (cost-effective, basic shock absorption)
- PPS: Self-adjusting pneumatic cushioning (auto-adapts to load/speed changes, reduces setup time, boosts process reliability)
- PPV: Manually adjustable pneumatic cushioning (for precise control in critical applications)
- Modular Flexibility:
- Double-acting operation (standard)
- Anti-rotation option (prevents rod twist for precision tasks)
- Multi-side sensor slots (3-sided profile for easy proximity switch mounting)
- Safety variants: Clamping unit (DSBC-...-C) for position holding; end-position locking (DSBC-...-E1/E2/E3) as a drop guard in pressure loss scenarios
- Environmental protection: Bellows kit (DSBC-...-P2) for rod/ seal protection against dust/debris; EX4 variant for explosive atmospheres
- Durable Construction:
- Coated die-cast aluminum covers
- Anodized aluminum cylinder barrel
- Hard-chromium plated high-alloy steel piston rod (corrosion-resistant, long wear life)
- Polyacetal piston with polyurethane seals (low friction, reliable sealing)
📏 Technical Specifications (Key Data)
- Bore sizes: 32 mm – 125 mm (standard); custom options available
- Stroke range: 25 mm – 3,000 mm (flexible for short/long travel needs)
- Position detection: Proximity switch compatible (3-sided sensor grooves for easy installation)
🛠️ Applications: Where DSBC Shines
The DSBC’s compact footprint and versatile performance make it ideal for:
- Precision automation: Pick-and-place, assembly lines, robotics (anti-rotation option for orientation-critical tasks)
- Packaging machinery: Labeling, sealing, carton handling (space-saving design fits tight machine frames)
- Electronics manufacturing: PCB handling, component insertion (clean operation, low friction)
- General machinery: Material handling, clamping, pressing (modular variants adapt to diverse needs)
- Safety-critical systems: End-position locking/clamping units for load holding in case of pressure loss
🔧 Installation & Maintenance: Easy to Use, Low Upkeep
- Universal mounting: Comprehensive accessory range (flanges, clevis feet, trunnion supports, etc.) for any orientation (horizontal, vertical, angular)
- Long service life: Robust materials and precision engineering minimize wear; easy access to seals/parts simplifies maintenance and reduces downtime
