P10..maintenance-free and robust
P10 is a leaded, robust sliding material with maximum tribological performance. It is designed for maintenance-free, dry-running applications, but can also be employed in systems with liquid lubrication. The use of grease as a lubricant with P10 is only possible to a limited extent, and is not recommended.
The solid lubricant mass is produced in a specially adapted mixing process. In a parallel, continuous sintering operation, bronze powder is sintered onto the steel or bronze back as a sliding layer. This produces a sliding layer with a thickness from 0.2 mm to 0.35 mm and a pore volume of approx. 30 %. Next, the cavities are filled with solid lubricant by means of impregnating rollers.
This process step is controlled in such a way that a running-in layer of solid lubricant up to max. 0.03 mm thick is produced above the sliding layer. In further thermal treatments, the characteristic properties of the material system are adjusted, and the required thickness tolerances of the composite material are produced using controlled roller pairs.
Important!The materials P10 and P11 contain lead and must therefore not be used in the food sector!
Standard designs are:
Sliding elements in a great variety of designs are produced from P10 and P11 in cutting, stamping and shaping processes.
In a final step, plain bearings manufactured from P10 undergo corrosion protection treatment on the bearing back, face reliefs and striking faces.
Standard version: Tin
layer thickness: approx. 0.002 mm
Additionally, P10 plain bearings can be supplied with improved corrosion protection coating “Zinc, transparent passivated”, on request.
Tin is used as temporary corrosion protection and an assembly aid.
