Saint-Gobain Performance Plastics has made its Norglide composite bearings range available for hydraulic pump applications in heavy-duty vehicles across Europe and Asia, including the UK, Germany and China.

The composite bearings ensure friction control within pump applications throughout the long life of the mechanism. They also help manufacturers comply with carbon dioxide (CO2) emissions standards by helping to reduce fuel consumption during pump operation.

Composed of a self-lubricating liner of polytetrafluoroethylene (PTFE) on a laminated metal backing, Norglide composite bearings are said to maintain smooth movement between the shaft of piston pumps and the outer housing.

Their split-ring design is smaller and lighter than traditional products for pump applications, allowing manufacturers to shrink the footprint of their pumps and use smaller, more efficient motors to further reduce fuel consumption. This supports pump manufacturers’ CO2 emissions reduction efforts for compliance standards.

Further benefits

  • Norglide bearings are designed to be self-lubricating and wear resistant.
  • PTFE can tolerate operating temperatures of up to 260ºC, while the laminated metal backing can withstand the high stresses experienced within pump applications.
  • The use of specialised filler compounds within the PTFE liner minimises wear, offering consistent maintenance-free composite bearing performance throughout the lifetime of the pump.
  • The smooth movement offered by PTFE reduces the energy required to rotate the mechanism’s drive, decreasing fuel consumption and enhancing energy efficiency.
