Product Features
- Durable Bronze Construction: FB090 bronze bearings are manufactured from a solid strip of CuSn8 bronze (DIN 17663) with an optimized diamond-shaped lubrication pocket pattern. This design ensures exceptional strength and longevity under demanding operational conditions.
- Superior Self-Lubricating Properties: The diamond-shaped indentations on the sliding surface act as reservoirs for grease or oil, significantly extending lubrication intervals and reducing maintenance needs. This feature is crucial for applications where frequent relubrication is challenging.
- High Load Capacity: Designed to withstand heavy radial and axial loads, these bearings are ideal for applications requiring robust performance. Their solid bronze composition allows them to handle high pressures and shocks without deformation.
- Corrosion and Wear Resistance: The tin-bronze alloy provides excellent resistance to corrosion and wear, making the FB090 bearing a reliable solution for harsh environments and aggressive media.
Product Description
The FB090 Bronze Wrapped Bearing is an engineered solution for a wide range of industrial applications requiring reliable self-lubricating plain bearings. Constructed from high-density CuSn8 bronze, these bushings and sleeves are designed to operate with minimal friction and wear. The unique indentation pattern on the inner surface facilitates the distribution of lubricant, enhancing bearing life and efficiency. This design makes the FB090 suitable for both grease-lubricated and dry-running applications, offering a versatile solution for rotating, oscillating, and linear movements. Our FB090 series complies with ISO 3547 standards, ensuring a high-quality and consistent product for your machinery needs.
This product is a cost-effective alternative to traditional cast bronze bushings and is widely used in hydraulic cylinders, agricultural machinery, construction equipment, and lifting devices where a durable, maintenance-reduced bearing is essential. The standardized dimensions simplify installation and replacement, making it a preferred choice for new designs and equipment repair.
Application Areas
This product is commonly used across various industrial sectors for applications such as:
- Agricultural equipment (tractors, harvesters)
- Construction machinery (excavators, loaders)
- Hydraulic cylinders and pneumatic systems
- Automotive suspension systems
- Lifting and conveying equipment
Common Sourcing Inquiries
1. How does the FB090 bronze wrapped bearing compare to sintered bronze bushings for high-load applications?
While sintered bronze bushings are effective for light to medium loads, FB090 wrapped bronze bearings offer superior performance for high-load and low-speed applications. The solid CuSn8 bronze material provides significantly higher compressive strength and heat dissipation. The integrated lubrication pockets of the FB090 design hold a larger volume of grease, which is critical for extending service life in demanding environments. For specific load calculations, we recommend consulting our technical team to ensure the optimal bearing size and material for your project.
2. What specific maintenance procedures are required for FB090 bearings in industrial machinery?
One of the primary advantages of the FB090 self-lubricating bushing is its reduced maintenance requirement. The diamond-shaped lubrication indentations are designed to retain and distribute lubricant over an extended period. While some applications can run without additional lubrication, for optimal performance and longevity, periodic relubrication is recommended, particularly in dusty or contaminated environments. The specific frequency of lubrication will depend entirely on your operating conditions, including load, speed, and temperature. Our engineers can provide a complimentary analysis based on your machinery's duty cycle to establish a tailored maintenance schedule.
