Heidelberg Spring Pin 00.530.0254 | 4×38 & 4×32 Tension Pin

Technical Specifications & Industrial Standards

This original Heidelberg Spring Pin / Tension Pin (Spannstift / Spannhülse DIN 1481) is engineered to withstand continuous shear stress and dynamic kinetic forces inside high-output printing environments. Designed as a self-retaining slotted spring sleeve, it contracts upon insertion into a 4 mm pilot hole, applying continuous outward expansion force against the housing walls to keep levers, side plates, and sheet stop assemblies locked in place.

• Official Part Name: Spring Pin / Tension Sleeve / Slotted Roll Pin (Spannstift / Spannhülse)

• Primary Part Number: 00.530.0254

• Part Number Variations & Dimensional Equivalents:

  • 00.530.0254 / 00.530.0254/ (Base OEM codifications)

  • Dimensional Variations: Cataloged as 4×38 mm (Spring Pin 4×38) in commercial distributor parts indices and as 4×32 mm (Spannhülse DIN 1481 4×32 / Spring Pin 4×32) in official technical parts documentation. Both variations share identical 4 mm nominal outer diameter tolerances and high-shear steel construction.

• Manufacturing Standard: Conforms to DIN 1481 / ISO 8752 slotted spring pin specifications.

• Material: High-tensile, fatigue-resistant hardened spring steel with anti-corrosive industrial coating.

• Country of Origin: Germany

Guaranteed Press Compatibility

This heavy-duty slotted spring pin is factory-certified for exact drop-in fitment across multiple mechanical sub-assemblies (delivery gripper units, side plates, and sheet stop linkages) in Heidelberg sheetfed offset presses:

• Heidelberg Speedmaster SM 102 / SM 102F

• Heidelberg Speedmaster CD 102

• Heidelberg Speedmaster SM 74

• Heidelberg GTO Series (GTO 46 / GTO 52)

Key Benefits for Your Printing Press

• Vibration Resistance & High Shear Strength: Maintains structural radial tension under continuous high-speed runs, preventing pins from walking out or shearing under heavy kinetic loads.

• Micron-Exact Mechanical Alignment: Eliminates micro-backlash between interacting linkages, preserving accurate sheet registration and smooth delivery mechanics.

• Simple Plug-and-Play Maintenance: Mounts smoothly using standard roll pin punches into factory-drilled 4 mm pilot holes, enabling rapid repairs during scheduled press service windows.
