MAINTENANCE-FREE PLAIN BEARINGS
Bronze or brass materials with solid lubricant pins – maintenance-free
MATERIAL CHARACTERISTICS
In these plain bearing materials, solid lubricants are embedded in a macro-depot system in such a way that permanent self-lubrication of the plain bearing is ensured without additional lubricants. The overlapping arrangement of the depots guarantees lubrication of the entire bearing surface.
Highly wear-resistant copper alloys are used as base materials for this maintenance-free plain bearing variant, selected according to operating conditions. The combination of copper alloy and solid lubricant depots provides the ideal conditions for your plain bearing designs.
- Permanent self-lubrication of the plain bearing, therefore maintenance-free
- High corrosion resistance depending on base material
- High dynamic and static load capacity
- Suitable for use both dry and in liquids
- Consistently low coefficient of friction
- Elimination of contact corrosion, fretting and galling (seizure)
- Suitable for high- and low-temperature applications
- Good thermal conductivity
- Vibration-dampening, low-noise
- Resistant to dirt and impact
- No stick-slip
