Advantages of maintenance-free plain bearings
Essential advantages of maintenance-free plain bearings with lubricating plugs are:
- Suitable for corrosive environments
- High load capacity
- Suitable for impact loads and vibrations
- Suitable for high temperatures
Applications of maintenance-free plain bearings
These plain bearings are most suitable for applications involving a high loading and requiring maintenance-free operation. Common applications are:
- Flood/lock gates
- Iron and steel industry
- Furnace construction
- Mold construction
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.
Maintenance-free plain bearings are provided with fixed lubricating plugs as standard. Additional lubrication is recommended for very low or very high speeds.
