FB090 Bronze Wrapped Bushing Bearing Manufacturers

FB090 bronze bearings use specially formulated high-density copper alloy strips as the base, and can be rolled with diamond or hemispherical oil pockets and oil grooves on the surface according to user needs. This product has the advantages of high density, strong load-bearing capacity, good wear resistance, and long service life. It can replace traditional cast copper sleeves, thereby reducing the size of the machinery and reducing costs.

FB090 has been widely used in lifting machinery, engineering machinery, automobile tractor chassis, machine tool industry, mining machinery and other fields. In addition, it can also be processed into bearings, flange sleeves, thrust washers, ball bowls and other parts.

FB090 Bronze Wrapped Bearing Industry knowledge

In modern industrial design, the trend toward miniaturization and high power density requires components that offer high performance within a compact footprint. The Bronze Wrapped Bushing Bearing is specifically engineered to meet these demands through its thin-wall structural design. By utilizing high-strength cold-rolled bronze strips, such as CuSn8, Zhejiang Shuangnuo Bearing Technology Co., Ltd. produces Bronze Wrapped Bushing Bearing solutions that provide exceptional load-bearing capacity while occupying minimal radial space. With nearly 10 years of focus on self-lubricating technology, Zhejiang Shuangnuo Bearing Technology Co., Ltd. ensures that these thin-walled components facilitate both mechanical efficiency and superior thermal management in demanding applications.

The Advantages of Thin-Wall Structural Engineering

The thin-wall design of wrapped bushings provides two primary technical benefits that traditional thick-walled cast bearings cannot match:

  • Maximum Space Efficiency: The reduced wall thickness—typically ranging from 1.0mm to 2.5mm—allows engineers to reduce the overall size and weight of the housing and shaft assembly. This is critical for mobile machinery, such as agricultural and construction equipment, where weight reduction directly impacts fuel efficiency.
  • Enhanced Heat Dissipation: Heat is the primary enemy of bearing longevity. In a thin-wall Bronze Wrapped Bushing Bearing, the thermal path from the friction interface to the heat-dissipating housing is significantly shortened. This allows for rapid cooling of the bearing surface, preventing the breakdown of the lubrication film and reducing the risk of thermal expansion-induced seizing.
  • High Load-to-Weight Ratio: Despite their slender profile, these bushings leverage the high tensile strength of phosphor bronze (CuSn8) to support massive radial loads, making them a robust alternative to much larger solid bronze components.

Technical Parameter Comparison: Thin-Wall Wrapped vs. Standard Cast Bronze

Zhejiang Shuangnuo Bearing Technology Co., Ltd. ensures the quality of these high-performance materials through independent casting of raw materials and rigorous spectrometer testing. The following table illustrates the technical advantages of our thin-wall wrapped design:

Parameter Standard Cast Bronze (C93200) Shuangnuo Thin-Wall Wrapped Bronze
Wall Thickness Range 5.0mm - 15.0mm 1.0mm - 2.5mm
Material Hardness (HB) 70 - 100 110 - 150 (Cold-worked CuSn8)
Radial Load Capacity (P) Standard High (Up to 120 N/mm² static)
Thermal Conductivity Path Long / Higher resistance Short / Rapid Dissipation
Weight Reduction Baseline Approx. 60% - 75% lighter

Application and Technical Performance FAQ

  • Does the thin-wall design compromise the structural integrity?

    No. Zhejiang Shuangnuo Bearing Technology Co., Ltd. uses cold-rolled phosphor bronze which has a much higher density and tensile strength than cast alloys. When press-fitted into a housing, the thin-wall bushing gains additional support from the rigid outer structure.

  • How does the thin-wall structure handle lubrication?

    The interior surface of our Bronze Wrapped Bushing Bearing is precision-stamped with diamond or ball-shaped indents. These pockets store grease effectively, and because the wall is thin, the grease remains closer to the metal-to-metal interface, ensuring constant boundary lubrication.

  • Why is Zhejiang Shuangnuo's independent casting beneficial for this product?

    By casting our own CuSn8 alloys, we ensure the tin content and phosphorus levels are precise. This precision is what allows the bronze to be rolled into thin strips without cracking, maintaining the high hardness required for thin-wall durability.
