CNC Machined Metal Bushing

2025-05-13 09:47:56

Our Metal Machined Bushings are precision-engineered components designed to reduce friction, absorb shock, and serve as spacers or sleeves between moving parts. Manufactured using advanced CNC Machining technology, each CNC machined bushing is crafted to meet exact specifications, ensuring optimal fit and performance in demanding industrial and mechanical applications.

Whether you need custom CNC metal bushing parts for automotive assemblies, industrial equipment, or heavy-duty machinery, we offer reliable solutions with tight tolerances and a variety of Material options including stainless steel, brass, aluminum, bronze, and carbon steel.

CNC Machined Metal Bushing


Material Options

We offer a wide range of materials to suit different use cases and environmental conditions:

  • Stainless Steel (SS304, SS316, 17-4PH): Corrosion-resistant and ideal for harsh environments

  • Brass (HPb59, C3604): Excellent machinability, conductivity, and wear resistance

  • Aluminum (6061-T6, 7075): Lightweight and durable, perfect for high-performance systems

  • Carbon Steel (1018, 4140): Strong and cost-effective for structural applications

  • Bronze (C93200, C95400): Known for low friction and wear resistance, ideal for sleeve bushings

All precision metal bushings can be customized according to your dimensional and material requirements, with RoHS-compliant material certifications available.


CNC Machining Capabilities

We utilize state-of-the-art CNC turning and milling equipment to produce high-precision metal CNC bushings. Key capabilities include:

  • Tolerances: Up to ±0.005mm

  • Surface Roughness: Ra ≤ 0.8μm

  • Thread Types: Metric/Imperial (internal/external)

  • Machining Types: CNC turning, boring, reaming, grooving

  • Batch Flexibility: Support for both prototyping and bulk orders

Our advanced production lines ensure consistency in every machined metal sleeve bushing, meeting the demands of high-performance mechanical systems.


Surface Finishes & Treatments

To improve durability and application-specific performance, we provide optional surface treatments for all custom machined bushings:

  • Anodizing (for aluminum bushings)

  • Electroplating / Zinc Plating

  • Nickel or Chrome Plating

  • Black Oxide Coating

  • Passivation (for stainless steel bushings)

  • Oil or Anti-rust Coating

These treatments help extend service life, reduce wear, and improve corrosion resistance in various working environments.


Application Industries

Our machined metal bushings are widely used across multiple sectors:

  • Automotive – For shock absorption, suspension components, and steering assemblies

  • Industrial Machinery – As wear-resistant bushing components in rotary equipment

  • Robotics and Automation – Smooth axis movement and modular component mounting

  • Aerospace and Defense – High-tolerance machined bushings in aircraft assemblies

  • Electronics and Appliances – As metal spacer bushings and heat-resistant inserts

  • Agricultural Equipment – Durable metal sleeve bushings for heavy-duty operation

We also support customers in the marine, construction, and medical device industries.


Customization & OEM Services

We provide full OEM/ODM customization for precision turning metal bushings, including:

  • Dimensions: Inside and outside diameters, wall thickness, length, tolerances

  • Threading: Internal, external, metric, UNC, UNF or BSP threading

  • Material Selection: Match with environmental and load-bearing requirements
