Introduction: Powering Industrial Reliability with CuSn8 Bronze Bushings

In industries where downtime is costly and performance is critical, VIIPLUS delivers ​CuSn8 Wrought Bronze Bushings – precision-engineered components designed to withstand extreme loads, corrosive environments, and high-speed operations. Crafted from high-grade ​tin-based bronze alloy (CuSn8), these bushings combine durability, self-lubrication, and thermal efficiency to optimize machinery performance in sectors like mining, construction, and automotive engineering.


Why VIIPLUS CuSn8 Bronze Bushings? Key Features

1. Premium CuSn8 Bronze Alloy

  • Wear & Corrosion Resistance: Thrives in abrasive, high-moisture, and chemically aggressive environments.
  • Self-Lubricating Design: Diamond-shaped oil pockets retain grease, reducing friction by ​40% and minimizing maintenance.
  • Thermal Conductivity: Efficient heat dissipation prevents overheating, extending component lifespan.

2. Precision Manufacturing

  • Wrapped/Rolled Construction: Lightweight, thin-walled design reduces machinery weight without compromising strength.
  • Tolerance Compliance: Housing (H7), shaft (IT7/IT8), and post-installation ID (H9) ensure seamless integration.

3. Robust Performance

  • High Load Capacity: Supports static loads up to ​120 N/mm² and dynamic loads of ​40 N/mm².
  • Temperature Resilience: Operates flawlessly from ​**-50°C to +200°C**, ideal for extreme conditions.
