Maintenance-free plain bearings

Maintenance-free plain bearings with lubricating plugs

Self-lubricating maintenance-free plain bearings for heavy-duty conditions

Maintenance-free plain bearings with lubricating plugs are suitable for heavy loads, high temperatures, vibrations and for use in corrosive environments. By using CuAI10Ni with specific lubricating plugs, the maintenance-free plain bearing can also be used in applications with salt water.

Materials

The maintenance-free plain bearings with lubricating plugs are made from CuZn25Al5 and are fitted with lubricating plugs. CuZn25Al5 is brass that has copper and zinc as its basis and is a construction material characterized by a high static load capability. As well as CuZn25Al5, there are many other alloys suitable for both the bearing and the lubricating plugs.

Lubrication

Maintenance-free plain bearings are provided with fixed lubricating plugs as standard. Additional lubrication is recommended for very low or very high speeds.
