Custom Sleeves & Bushings Manufacturing Solutions

Precision CNC Machining & Non-Standard Component Fabrication

In high-precision mechanical systems, fluid power controls, and dynamic power transmissions, Sleeves and Bushings perform indispensable functions: reducing wear, isolating vibration, ensuring strict alignment, and enabling seamless fluid sealing. As a dedicated provider of custom CNC machining, we offer end-to-end manufacturing for high-precision, wear-resistant non-standard sleeves and bushings tailored strictly to your engineering specifications.

1. Core Machining Capabilities & Technical Standards

Precision sleeve and bushing components require tight geometric tolerances, optimal surface integrity, and controlled clearances. Our facility is equipped with multi-axis CNC turning centers, high-speed CNC milling machines, and precision grinding equipment to meet stringent standards:

Technical Parameter Manufacturing Specification & Capability
Dimensional Tolerance Consistently controllable down to ±0.005 mm (±0.0002 in)
Surface Roughness

Standard turning/milling: Ra 0.4 – Ra 0.8 µm

 

Honing / cylindrical grinding: up to Ra 0.2 µm
Wall Thickness Control Thin-wall sleeves down to 0.5 mm with zero thermal or mechanical deformation
Size Range Micro bushings (OD starting at 2.0 mm) up to large shaft sleeves (OD up to 500 mm)
Concentricity & Runout High-precision internal/external cylindrical concentricity within 0.005 mm

2. Comprehensive Material Options & Surface Treatments

We process a wide range of metals, specialty alloys, and high-performance engineering plastics depending on your operational conditions (high load, corrosion, extreme temperatures, self-lubrication):

Metallic Materials

  • Copper Alloys: Brass (C36000), Bronzes (Tin Bronze, Aluminum Bronze C95400, Phosphor Bronze), Beryllium Copper (high strength/conductivity).

  • Stainless Steels: 304, 316L (corrosion resistant), 17-4PH, 420, 440C (high-hardness hardened stainless steel).

  • Carbon & Alloy Steels: 45# / AISI 1045, 40Cr / AISI 5140, 20CrMnTi (ideal for carburizing and heavy wear resistance).

  • Lightweight Metals: Aluminum Alloys (6061-T6, 7075-T6), Titanium Alloys (Grade 5 / Ti-6Al-4V for aerospace & medical).

Engineering Plastics & Polymers

  • POM / Delrin (Polyacetal): High dimensional stability, low friction coefficient, excellent machinability.

  • Nylon & PEEK: PA66, PEEK (Polyether ether ketone) for high-temperature, wear-resistant, and oil-free environments.

  • PTFE (Teflon): Extreme chemical inertness and superior self-lubricating properties.

  • UHMW-PE & PP: High impact resistance and lightweight wear surfaces.

Secondary Processing & Surface Finishing

  • Hard Anodizing, Electroplating (Hard Chrome, Nickel, Zinc), Heat Treatments (Carburizing, Nitriding, Vacuum Hardening), and Self-Lubricating Coatings (PTFE / MoS2 spray coating).
