Heavy Loads

Gearboxes, bearings, wire ropes, conveyors chains, are often subjected to heavy loads. Several phenomena may arise:

  • Wear due to fatigue (micropitting)
  • Wear due to adhesion
  • Corrosion
  • Abrasion
  • Noise
  • And so on

These different manifestations of wear occur when the protective lubricating film breaks down. As loads increase, contact temperatures rise, which accelerates wear. Lubricants are, in fact, forced away from areas of contact, resulting in dry friction.

Extreme Pressure (EP) and Anti-Wear (AW) properties play a decisive role. Their function is to prevent and/or limit metal-on-metal contact.
