Component Specifications

Definition
Alignment guide rails are precision-engineered linear motion components installed within machine main frame bodies to ensure accurate, repeatable, and stable movement of sliding elements. They provide rigid guidance, minimize deflection, and maintain positional accuracy under operational loads through precisely machined surfaces and mounting interfaces.
Working Principle
Guide rails work by providing a hardened, precision-ground surface along which linear bearings or sliders move with minimal friction. They maintain alignment through geometric accuracy and rigid mounting, distributing loads evenly to prevent misalignment and ensure smooth, predictable motion along a defined axis.
Materials
Typically made from hardened steel (e.g., AISI 52100, 1045 carbon steel) or stainless steel (e.g., 440C, 304), often with surface treatments like chrome plating, nitriding, or induction hardening to enhance wear resistance and corrosion protection.
Technical Parameters
  • Width 15mm to 100mm
  • Height 20mm to 150mm
  • Length Customizable from 100mm to 6000mm
  • Hardness 58-62 HRC (surface)
  • Load Capacity Up to 50 kN static, 20 kN dynamic
  • Surface Roughness Ra ≤ 0.4μm
  • Straightness Tolerance ≤0.01mm per 1000mm
Standards
ISO 10285, DIN 645, ISO 3408
