P14...Maintenance-free and environmentally friendly

P14 is a lead-free standard sliding material with a high tribological performance. Is is designed for maintenance-free, dry-running applications, particularly in the food sector. It may also be employed in systems with liquid lubrication, however. The use of grease as a lubricant with P14 is only possible to a limited extent, and is not recommended.

Matrial manufacture

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 back as a sliding layer. This produces a sliding layer with a thickness of 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.

Note: P14 cannot be used in water (Alternative: P10, P147)

Plain bearing production

Sliding elements in a great variety of designs are produced from P14 in cutting,
stamping and shaping processes.

Standard designs are:

  • Cylindrical bushes
  • Flange bushes
  • Thrust washers
  • Strips

In a final step, plain bearings manufactured from P14 undergo anti-corrosion treatment on the bearing back, end faces and striking faces.

Standard version: Tin
Layer thickness: approx. 0.002 mm

Note: Tin is used as temporary corrosion protection and an assembly aid.

Characteristics of P14

  • Lead-free
  • Very low stick-slip tendency
  • Low wear
  • Low friction coefficient
  • No tendency to fuse with metal
  • Very low tendency to swell

Preferred areas of application

  • Maintenance-free operation in dry-running conditions where lead-free parts are required
  • Rotating or oscillating movements up to a speed of 1m/s
  • Linear movements
  • Temperature range -200°C to 280°C

Hydrodynamic operation

Use in hydrodynamic conditions is possible without problems up to a sliding speed
of 3 m/s. In continuous operation above 3 m/s, there is a risk of flow erosion or cavitation. Motorservice offers the calculation of hydrodynamic operating states as a service.
