Rolled Wrapped Bronze Bushings with Metric Oil Indentations are a type of precision-engineered bushings made from rolled and wrapped bronze material. These bushings feature indentations or grooves specifically designed for oil retention, allowing for lubrication and reduced friction in high-speed or high-load applications. The metric dimensions of the bushings refer to the standardized sizes and measurements used in the metric system of measurement.

The rolling and wrapping process of the bronze material results in bushings with superior strength and durability while maintaining flexibility and conformability. The oil indentations provide channels for lubricant to flow and distribute evenly, minimizing wear and tear on the bushing and extending its service life.

These bushings are commonly used in various industrial applications where precision movement and reliable lubrication are crucial, such as in machinery, automotive components, and other mechanical systems. The metric oil indentations ensure compatibility with metric-sized equipment and components, making installation and maintenance easier.

What is FB090 wrapped bronze bearing?

FB090 Wrapped Bronze bearings are made completely of bronze. They are particularly suitable for applications, which must be re-lubricated due to dirty environments.

The sliding surface is provided with lubrication pockets, which contribute to the enhanced lubrication performance.

This bushing is produced in accordance with ISO 3547 and DIN 1494.

Where to use FB090 wrapped bronze bearing?

These bearings are suitable for both radial and axial movements.

The bushings are well suited for machinery in dirty environments where shock loads and/or vibrations occur.

Examples of applications are:

• Agricultural machinery
• Hoisting equipment
• Construction machinery
• Forest machinery

Why choose wrapped bronze bearing?

• Insensitive to dirty environments
• Resistant to shock loads and vibrations at slow speeds
• Good resistance to corrosive conditions

The basic features

With CusN6.5P0.1 or CusN8P0.3 bronze as the matrix, the bronze hole layout bearing is designed with uniform and orderly oil filling holes. Lubricating oil is injected after assembly. The bearing has the advantages of large oil storage, convenient installation, and small design machine, and can replace the copper sleeve to use, greatly reducing the cost
The inner hole of the product is full of and oil pits, which can store a large amount of oil during use and extend the refueling interval.
2. Less oil lubrication, suitable for occasions where it is difficult to add oil or water lubrication;
3. Good wear resistance, low friction coefficient, and long service life;
4. It can be used within the range of -100℃ to 200℃;
5. Good coupling performance, low noise, no pollution;
6. Thin-walled structure, lightweight, can reduce the mechanical volume;
7. The matrix has high density, gas-free shrinkage cavity, and large bearing capacity;
Currently has been widely applied to various mechanical sliding parts, such as automation machinery and equipment (scale, swing, slide, bending, cyclotron, turning parts) of the hydraulic cylinder guide bush, textile machinery, plastic molding machine, die-casting machine, rubber machinery, hydraulic truck, automobile, motorcycle industry, ports, water conservancy, construction, agricultural machinery, etc.

Long service intervals under severe operating circumstances.

Wrapped bronze bearings are ideal for applications where there are high levels of contamination. Their running surface is provided with diamond-shaped lubrication pockets or a hole pattern. The lubrication pockets must be filled with grease when the bearing is installed. The wrapped bronze bearings are produced according to the ISO 3547.

Materials

Wrapped bronze bearings are made entirely from phosphor bronze CuSn8. CuSn8 is characterized by the purity of the alloy with only a very low level of impurities. Wrapped bronze bearings are produced from strips that are subsequently wrapped and calibrated.

Lubrication

Wrapped bronze bearings must be lubricated with grease or oil on installation. A good quality lubricant is essential as it will reduce friction and wear by forming a film between the plain bearing and the shaft. For heavily contaminated applications, we recommend sealing off the bearing. This will protect both the bearing and the lubricant.

Advantages

The main advantages of wrapped bronze bearings include:

• Long service intervals
• Not affected by impurities
• Suitable for corrosive environments
• Suitable for impact loads and vibrations at low speeds
• Good heat dissipation

Applications

Wrapped bronze bearings are especially suited to severe operating conditions where frequent maintenance is not possible. Common applications are:

• Agricultural vehicles
• Lifting gear
• Offshore
• Excavators
