Maintenance-free oilless bearings with lubricating plugs
Self-lubricating maintenance-free oilless bronze bush bearings for heavy-duty conditions
Maintenance-free oilless bronze bush bearings with lubricating plugs are suitable for heavy loads, high temperatures, vibrations and for use in corrosive environments. By using CuAI10Ni bronze alloy with specific lubricating plugs, the maintenance-free oilless bearing can also be used in applications with salt water.
CuAl10Ni is an aluminum bronze alloy typically embedded with specific lubricating plugs, such as graphite, to enhance its self-lubricating capabilities. This alloy is valued for its high strength, excellent wear and corrosion resistance, making it ideal for heavy-duty applications under high loads and speeds. The embedded graphite acts as a solid lubricant, reducing the need for maintenance and allowing the alloy to perform well in dry-running conditions. Products like bushings and bearings made from CuAl10Ni are especially suited for situations where continuous smooth operation is critical and maintenance access is challenging.

Lubricating Plugs: These are components that allow for the lubrication of bearings without the need for disassembly. They can be used to inject lubricant into the bearing, which can extend the life of the bearing and reduce the need for maintenance.
Thermal Conductivity: Copper alloys have excellent thermal conductivity, allowing the bearing to dissipate heat effectively, which is important when operating under high-temperature conditions.
Fatigue Resistance: The fatigue resistance of copper alloys contributes to the long service life of the bearings, even under fluctuating loads.
