Wrapped bronze bushings with flanged sizes and lubrication pockets offer superior performance and durability in various industrial applications. These bushings are constructed from high-quality bronze alloy, which is wrapped around a steel core to provide enhanced strength and wear resistance.
The flanged size design allows for easy installation and secure positioning within the housing. The lubrication pockets, strategically positioned along the bushing's surface, ensure consistent lubrication and reduced friction during operation. This not only improves the bushing's efficiency but also extends its service life.
Wrapped bronze bushings are widely used in applications that require precise alignment and smooth rotation, such as machine tools, pumps, and transmissions. Their ability to withstand high loads and temperatures makes them suitable for a variety of challenging environments.
The combination of wrapped bronze construction, flanged size design, and lubrication pockets ensures that these bushings are a reliable choice for any industrial application that demands superior performance and durability.
092 bronze bushings are deriving from 090; the difference between 090 & 092 bronze bushings is Indentations on the working surface, which
substituted by Through-holes. These holes will allow greater
capacity to collect lubricant, which builds up a lubrication film
at the start of the movement and reduce the friction. It is suitable for high load, lower speed applications like construction, Transport, and agriculture
machinery.

The bearings are wrapped from a cold-formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are fitted with diamond-shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of the movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.
