VIIPLUS Wrapped Bronze CuSn8 Bushings: Precision Engineering for Extreme Durability
In industries where machinery endurance is non-negotiable, VIIPLUS Wrapped Bronze CuSn8 Bushings stand as a testament to innovation and reliability. Crafted from premium phosphor tin bronze (CuSn8P), these bushings deliver unmatched wear resistance, fatigue strength, and adaptability across demanding applications. Designed to meet DIN 1494 and ISO 3547 standards, VIIPLUS’s bushings are the go-to solution for industries prioritizing longevity and cost efficiency.
**What Are VIIPLUS Wrapped Bronze CuSn8 Bushings?**
These bushings are precision-engineered components made from homogeneous CuSn8P bronze, a high-performance alloy enriched with phosphorus (7.5–8.5% Sn, 0.01–0.4% P). The manufacturing process involves cold extrusion and precision rolling to create thin-walled bearings with uniform injection holes for optimal grease distribution. Key features include:
- Split Design: Easy installation without disassembling machinery.
- Sealed Ends: Integrated seals retain lubrication and block contaminants.
- Customizable Sizes: Available in IDs up to 240mm and configurations like flanges, sleeves, and washers.
Compliant with global standards, these bushings excel in medium-to-low-speed applications where reliability is critical.

Properties
- Economic solution for bronze bearing application due to a thin wall thickness. High load capability and good stability with low abrasion. Suitable for rough working conditions, good corrosion resistance. Lubrication holes for maximum grease storage and the lowest maintenance intervals.
Structure Characteristics and Applications:

wrapped bronze bushing is made of tin-bronze CuSn8 that is of high density, its surface is punched with oil apertures by certain angle and density therefore its easier to form an oil film when the bushing works. It has good anti-fatigue and load, anti-erosion anti-abrasion and load capacity. The products are widely applied in conditions of heavy load but low running velocity, such as on agricultural, buiding and engineering machines.

Product Benefits:
1.Saving large amount of bronze material and save the working hours normally spent for lathing the bronze bushing.
2.Compared with lathed bushings and roller bearings, it is lights and more cost-effective.
3.Various holes and dents can be made on the friction surface for grease storage, prolonging the lubrication interval to 5 times as long as required by the bronze bushing.
4.Extremely high load sustainability, especially suitable for coarse abrasion surfaces.
Standard products available: straight bushings, thrust plates and pressure bearings.
Non-standard products available: sleeve bushings, thrust plates, flanged bushing, bearing bushings, slide plates and steel bushing combination.
