· Custom Engineering: Available in cylindrical, flanged, thrust, and spherical structures.

Product Application

1. Machinery Bearings & Wear Components

Red Copper Bushings made in China are widely used in mechanical systems requiring high load capacity, low friction, and reliable wear resistance.

• Applied in gear reducers, hydraulic cylinders, pumps, cranes, and excavators
• Suitable for radial and axial load conditions
• Copper’s self-lubricating behavior helps reduce shaft wear and particle damage
• Available types: cylindrical, flanged, thrust, spherical bushings
• Custom options: oil grooves, graphite inlays, tailored wall thickness and tolerances

Zenko provides CNC-precision machining, centrifugal casting for large bushings, and surface finishing with Ra < 0.4 μm, supporting both prototyping and mass production with full quality traceability.

Electrical Grounding & Connector Components

Copper bushings also play a key role in electrical grounding and power distribution systems due to excellent conductivity and corrosion resistance.

• Used in switchgear, transformers, grounding systems, and enclosures
• Ensures stable electrical continuity and safe grounding performance
• Meets NEC, IEC 61439, and UL enclosure standards
• Material: C11000 ETP copper with up to 101% IACS conductivity 
• Surface options: tin, nickel, and silver plating for enhanced durability

Available designs include threaded grounding bushings, knockouts, reducers, and custom connector components. Each batch is tested in-house for conductivity, composition, and mechanical properties.

Automotive, Marine & Valve Applications

The quality Red Copper Bushings are also widely used in transportation and fluid control systems where strength, corrosion resistance, and fatigue performance are critical.

· Automotive: suspension, steering, stabilizer bar, and pedal pivot bushings

· Marine: propulsion systems and deck hardware exposed to saltwater environments

· Industrial valves: wear and sealing components under cyclic loading

Material options include:

· C95400 aluminum bronze (high-load marine/off-highway use)

· C93200 bearing bronze (general machinery applications)

· C17200 beryllium copper (high-strength aerospace-grade applications)
