Powder Metallurgy Shock Absorber Guide with Optional DU Bushing Assembly

A shock absorber guide, also known as a shock absorber rod guide, is an important internal component in automotive and motorcycle hydraulic dampers. It is generally installed in the upper section of the damper assembly and works with the piston rod, oil seal, and related sliding components.

Different damper designs require different guide configurations. Some applications use a standalone powder metallurgy rod guide, while others incorporate a DU sliding bushing to meet specific assembly and movement requirements.

XIAYI specializes in the development and manufacture of powder metallurgy shock absorber components. Its Shock Absorber Guide product range includes different configurations, such as steam-treated sintered guides and rod guides supplied with DU bushing assemblies.

Manufactured using iron-based powder metallurgy materials, the guides can be evaluated according to customer drawings, material specifications, dimensions, machining requirements, and surface treatment needs. They are intended for automotive shock absorbers, motorcycle suspension systems, and OEM component programs.

Manufactured from iron-based powder metallurgy materials through compaction, sintering, and required secondary operations.

This configuration is suitable for damper designs using a standalone rod guide assembly.

External geometry, mounting position, bore dimensions, and mating requirements can be reviewed according to customer drawings.

For damper designs requiring a sliding bearing interface, a DU bushing can be evaluated as part of the rod guide assembly.

This configuration combines a powder metallurgy body with a bushing component. Bushing dimensions, material layers, installation method, and fit clearance should be defined according to the piston rod and guide design.

Steam treatment is available as a surface finishing option for selected iron-based powder metallurgy rod guides.

Treatment conditions, surface appearance, and oxide-layer specifications can be reviewed according to the selected model and customer requirements. Applications with specific corrosion protection needs should be evaluated against the actual service environment.

Different automotive and motorcycle damper designs may require different guide dimensions and assembly configurations. XIAYI can review 2D drawings, 3D models, or physical samples to assess manufacturing requirements.

Projects involving special mounting features, bushing configurations, or material specifications can be defined during product development, including drawing revisions, critical dimensions, and acceptance criteria.

The following values are taken from separate existing product listings and are provided as representative specifications.

For automotive and motorcycle damper manufacturers, sourcing a rod guide involves more than dimensional confirmation. Product revision control, material requirements, batch management, and project quality documentation may also be required.

XIAYI can discuss the following support according to individual project needs:

For OEM programs with strict quality documentation requirements, the PPAP submission level, control plan, and inspection requirements should be defined during product development.

To identify the appropriate guide configuration and prepare a quotation, please provide:

A product drawing or physical sample.

Mating piston rod diameter and surface treatment requirements.

Critical guide dimensions, including bore, outside diameter, and thickness.

Whether a DU bushing assembly is required.

Material, density, hardness, and surface treatment specifications.

Estimated order quantity, annual demand, and quality documentation requirements.

XIAYI can assess the product specifications and manufacturing route based on customer information, supporting customized development and volume supply of shock absorber guides.

Q1: What is the difference between Shock Absorber Guide and Shock Absorber Rod Guide?

In shock absorber component sourcing, Shock Absorber Rod Guide is the more specific product name because it identifies the piston rod guiding function. Shock Absorber Guide can also be used as a broader product category keyword.

Q2: Can a shock absorber guide be supplied with a DU bushing?

A guide with a DU bushing assembly can be evaluated. The configuration, bushing dimensions, and installation method depend on the product drawing and mating piston rod requirements.

Q3: What material is used for XIAYI shock absorber guides?

Existing product specifications include an iron-based Fe-C-Cu powder metallurgy material system. Material properties should be confirmed against the relevant product model.

Q4: Can PPAP documents be supplied?

Relevant PPAP documentation can be discussed according to the OEM project's requirements. The actual submission content and level should be confirmed during project review.

Q5: How can I check compatibility with an existing shock absorber?

Please provide the guide drawing, mating piston rod dimensions, installation structure, and DU bushing requirements, if applicable. Compatibility can then be reviewed against the product dimensions and assembly design.
