Diamond Tilt Pad Thrust Bearings


Longer Life | Harsh Environments | No Seals

Waukesha Bearings has partnered with US Synthetic, the leader in diamond solutions, to offer breakthrough performance in diamond tilt pad bearing technology.

Combining the benefits of Waukesha's tilt pad thrust bearing design with the superior wear resistance of US Synthetic’s polycrystalline diamond (PCD) technology, the diamond tilt pad thrust bearing provides superior bearing performance and extended life in equipment operating at high loads and speeds in low-viscosity lubricants, abrasive fluids or corrosive chemicals.

Diamond tilt pad thrust bearings:

  • Have been run at speeds up to 39 m/s and unit loads up to 16 MPa
  • Simplify equipment and assemblies by eliminating the need for seals and separate lubrication systems
  • Can operate at a low coefficient of friction: between 0.05 and 0.08 in direct contact during starting mode. In hydrodynamic operation, friction is below 0.002.


About PCD 

PCD is not a diamond coating. It is a thick, manmade diamond surface ideally suited for operation in process fluids where abrasive particles can cause accelerated wear and failure with traditional bearing materials.

PCD is known for:

  • High thermal conductivity, which reduces localized temperature extremes that lead to bearing degradation
  • Low coefficient of friction, which decreases heat generation and reduces power loss
  • High hardness and fracture toughness, which resists wear from abrasive particles
