Composite dry sliding bearings, specifically the journal bearing type with coiled steel backing and (Polytetrafluoroethylene) bushing, are a reliable and efficient solution for various applications requiring low-friction, wear-resistant bearing surfaces. These bearings offer several advantages over traditional lubricated bearings, making them a popular choice in industries such as automotive, aerospace, and heavy machinery.
The coiled steel backing provides excellent structural support and stability for the bushing. This combination of materials ensures that the bearing can withstand high loads and pressures while maintaining its dimensional stability. The coiled steel also helps dissipate heat generated during operation, reducing the risk of thermal expansion and damage to the bearing.
The bushing is a key component of this type of bearing. is a synthetic fluoropolymer with excellent wear resistance, low friction coefficients, and good chemical stability. These properties make it an ideal material for bearings that require smooth, reliable operation over extended periods of time. The bushing is precision-fitted into the coiled steel backing, creating a uniform and smooth bearing surface.
Composite dry sliding bearings with coiled steel backing and bushing are often used in applications where traditional lubricated bearings are not feasible or desirable. For example, they are commonly found in high-temperature environments where lubricants may degrade or evaporate, as well as in cleanroom environments where lubricants can contaminate sensitive equipment. Additionally, these bearings require no maintenance or relubrication, reducing downtime and operational costs.
In summary, composite dry sliding bearings with coiled steel backing and bushing offer a reliable and efficient solution for applications requiring low-friction, wear-resistant bearing surfaces. Their excellent performance and durability make them a popular choice in a wide range of industries.

Journal Bearing Type—Coiled Steel Backing Bushings
Self-Lubricating Bearing Flanged Bushings
Lubrication should be done through the shafts or radial through the housings. All common grease-types or oil can be used.
Journal bearings, split seam steel backing, zinc plated bearing works excellent in any pivot or linkage application. For construction and farm equipment, this product is typically used in kingpins, rock shafts,differentials, hinges, pedals and many other pivot points.
