Product Description

 

ST52 Hollow Chrome Plated Rod ID Not Honed: A Practical Solution for Cost-Conscious Hydraulic Design

ST52 Hollow Chrome Plated Rod ID Not Honed is manufactured from seamless ST52 (E355) steel tubes. It features a precision-ground chrome plated outer surface with a raw, non-honed inner diameter. This rod is an excellent choice for applications where the interior surface doesn’t require precision sealing or close tolerance.

The external surface is treated with hard chrome plating (20–30 μm) for excellent corrosion and wear resistance. Because the ID is not honed, production cost is lower, making this rod suitable for cost-sensitive projects or applications where the tube is used primarily as a structural support or low-friction guiding shaft.

This rod is often used as a Hollow chrome hydraulic bar in basic hydraulic applications, as well as a Hollow chrome suspension rod in mobile equipment.

Why Choose ST52 Hollow Chrome Plated Rod ID Not Honed?

  • Cost-Effective Design
    The non-honed ID reduces production cost, ideal for projects where internal finish is not critical.
  • High Outer Precision
    OD is ground and hard chrome plated to ISO f7 tolerance, ensuring compatibility with seals, bushings, or linear motion parts.
  • Corrosion & Wear Resistance
    The chrome layer protects against surface damage, moisture, and abrasive environments.
  • Versatile Use Cases
    Applicable in Hollow chrome hydraulic bar designs, basic fluid movement rods, and mechanical guiding systems.
  • Weight Reduction Advantage
    The hollow structure cuts down weight while maintaining high bending resistance, perfect for Hollow chrome suspension rod applications in mobile and off-road equipment.

 

Common Applications

  • Lightweight piston rod systems
  • Guide tubes in automation or robotics
  • Boom arms in lifting machines
  • Telescopic hydraulic components
  • Suspension bars in agricultural or construction equipment
  • Fluid pass-through shafts (non-sealing)

The ST52 Hollow Chrome Plated Rod ID Not Honed is a great alternative when you don’t need the ID precision of a honed tube but still require external chrome quality and straightness.

 

Benefits Overview

  • Lower manufacturing and material cost
  • Widely used in general-purpose and light-duty hydraulics
  • Easier to machine or modify for threaded or welded assemblies
  • Reduces system weight in mobile or suspended structures
  • Ideal as Hard chrome hollow rod where internal flow or pressure is not a concern
