ADN Series ISO 21287 Compact Pneumatic Cylinder Assembly Kits

• Product Type: Pneumatic Cylinder Assembly Kit
• Series: ADN Series
• Standard Compliance: ISO 21287 (ensures dimensional interchangeability for mounting and key features of the assembled cylinder)

I. Operational Specifications (for Assembled Cylinder):

• Acting Principle: Typically Double-Acting (kits for Single-Acting versions may also be available depending on the manufacturer)
• Operating Medium: Compressed Air, filtered to ISO 8573-1:2010 [7:4:4] (lubricated or non-lubricated operation often possible)
• Operating Pressure Range:
  • Typically: 0.6 to 10 bar (0.06 to 1 MPa; approx. 9 to 145 psi)
  • (Note: Smaller bores like Ø12mm-Ø16mm, if offered as ADN-type, might have a minimum operating pressure closer to 1 bar)
• Proof Pressure: Typically 1.5 MPa (15 bar; approx. 217 psi)
• Ambient Temperature Range:
  • Standard Seals: -20°C to +80°C (-4°F to +176°F)
  • (Kits with specialized high/low-temperature seals will specify different ranges)
• Cushioning:
  • Standard: Elastic cushioning rings/pads at both ends (P-type or equivalent)
• Piston Speed Range: Typically 30 mm/s to 500 mm/s (varies by application, load, and bore size)

II. Dimensional & Constructional Parameters (Kit Components & Assembled Cylinder):

• Available Bore Sizes (Kit Selection):
  • Common ISO 21287 Bores: Ø20mm, Ø25mm, Ø32mm, Ø40mm, Ø50mm, Ø63mm, Ø80mm, Ø100mm
  • (Smaller ADN-type bores like Ø12mm, Ø16mm may also be available from some suppliers)
• Stroke Length (Configurable via Kit):
  • Components allow for assembly of various stroke lengths, determined by user cutting of barrel and piston rod stock.
  • Maximum Assembled Stroke Potential: Typically up to 300mm or 500mm, depending on bore size and manufacturer’s stock lengths.
• Piston Rod:
  • Material: High-tensile Stainless Steel (common) or Hard Chrome Plated Carbon Steel.
  • Thread: Male or Female (as per ISO 21287 for the selected bore size).
  • Options: Kits for non-rotating rod versions may be available for some ADN variants.
• Cylinder Barrel:
  • Material: Anodized Wrought Aluminum Alloy (profile tube).
  • Features: Often includes integrated T-slots on one or more sides for direct mounting of proximity sensors.
• End Caps:
  • Material: Die-cast Aluminum or Anodized Wrought Aluminum Alloy.
• Seals (Included in Kit):
  • Piston Seals: Typically PUR (Polyurethane) or NBR (Nitrile Rubber).
  • Rod Seals/Wiper: Typically PUR or NBR.
  • O-Rings & Static Seals: NBR or FKM/Viton (for optional high-temp kits).
• Magnetic Piston:
  • Typically standard or a selectable option within the kit for position sensing via external sensors.
• Mounting Options (for Assembled Cylinder):
  • Conforming to ISO 21287: Through-holes, internal threads in end caps. A comprehensive range of standardized mounting accessories (foot mounts, flanges, clevises, trunnions, etc.) are usually sold separately.

III. Kit Specifics:

• Kit Contents (General):
  • Cylinder Barrel Profile (often supplied in stock lengths for user cutting)
  • Piston Rod Stock (often supplied in stock lengths for user cutting and threading/machining)
  • Front End Cap Assembly
  • Rear End Cap Assembly
  • Piston Assembly (including magnet if applicable)
  • Complete Seal Set (piston seals, rod seal, wiper, O-rings, guide/wear rings, cushioning elements)
  • Assembly Fasteners (e.g., screws, retaining rings)
  • Lubricating Grease (for initial assembly)
• Customization Note: Assembly kits are designed to allow users to create cylinders of specific, often non-standard, stroke lengths by cutting the barrel and piston rod material to the required dimensions. Appropriate tools and machining capabilities are necessary.
