Component Specifications

Definition
A cylindrical, hardened steel rod that provides a smooth, low-friction linear path for moving parts in spring return mechanisms. It maintains precise alignment, prevents lateral deflection, and ensures consistent return motion by guiding components along a predetermined axis under spring force.
Working Principle
The guide rod operates by constraining the motion of a sliding component (such as a bushing or carriage) to a single linear axis. As the spring exerts force to return the mechanism to its neutral position, the rod ensures straight-line movement without binding or misalignment, reducing wear and maintaining operational accuracy.
Materials
Typically made from case-hardened steel (e.g., AISI 1045, 4140) or stainless steel (e.g., AISI 304, 316) with surface treatments like chrome plating or nitriding for corrosion resistance and reduced friction.
Technical Parameters
  • Length 100-500 mm
  • Diameter 8-25 mm
  • Hardness HRC 58-62
  • Load Capacity Up to 5000 N
  • Surface Finish Ra 0.4 μm or better
  • Straightness Tolerance 0.05 mm/m
Standards
ISO 286-2, DIN 1494
