Description

The Fabco-Air HPS-435 is a premium, industrial-grade short-stroke "Pancake" air cylinder engineered explicitly to provide high clamping and linear actuation force within exceptionally confined machine spaces. This heavy-duty pneumatic component features a massive 4-inch bore size combined with a precise 3/8-inch stroke length, generating immense thrust while maintaining a highly compact axial footprint. Equipped with Fabco-Air’s specialized non-rotating hex-profile piston rod (HPS Series), it completely eliminates axial twist and rotational play without the need for external guide bars. Machined with a rugged thick-walled aluminum body, self-lubricating bronze rod bushings, and high-purity nitrile seals, this double-acting cylinder provides dependable, low-friction operation across high-cycle automated assembly and stamping lines.
⭐ Key Features & Benefits
  • Compact Pancake Form Factor: Low-profile design maximizes power density, fitting into tight mechanical envelopes where standard tie-rod cylinders cannot.
  • Non-Rotating Hexagonal Rod: Unique 1-piece internal hex rod configuration prevents rod rotation, protecting custom tooling alignments during operation.
  • Massive Clamping Thrust: A large 4" bore surface area converts standard factory air pressure into aggressive clamping or press force.
  • Anodized Aluminum Body: Hard-coat anodized inner diameter provides superior corrosion protection and incredibly low internal wear friction.
  • Double-Acting Fluid Dynamic: Utilizes air ports on both ends to deliver fully controlled power strokes for both extension and retraction cycles.
🔧 Uses / Applications
  • High-Force Clamping Fixtures: Deployed extensively on automated welding benches, CNC machining tables, and multi-stage work-holding jigs.
  • Stamping & Press Sub-Assemblies: Ideal for small-scale material punching, stamping, coin-marking, or parts ejection systems.
  • Packaging & Conveyor Gates: Operates high-speed sortation gates, heavy-duty divert lanes, and vertical stopping pins on packaging lines.
  • Industrial Automation Machinery: Serves as a direct-fit replacement actuator inside electronic assembly machines and pick-and-place equipment.
