Project Description

Metal-Polymer Composite Material

Bronze Back + Porous Bronze Sinter + PTFE

Trusted & Reliable Bronze Backed Bushing

    • Rolled composite plain bearings according to DIN 1494 / ISO 3547
    • Bronze / PTFE sliding layer Maintenance-free High chemical resistance
    • Maintenance/lubrication
    • Lubrication is not required because of dry plain bearings with PTFE sliding layer.
    • However, additional lubrication is possible


Suitable for dry running and hydrodynamic bearing operation, good sliding and wear properties (no stick-slip effect), high resistance in seawater environments and salt solutions, RoHS compliant, good thermal conductivity, non-magnetic.

Maintenance-free Composite Bearing Bronze Backed

  • PTFE composite bearing design: The structure consists of a rigid steel or corrosion-resistant bronze backed (bronze backed) that provides ultra-high mechanical strength, while a porous sintered bronze interlayer impregnated with a homogeneous mixture of PTFE and lead provides low friction and high wear resistance.
  • The low friction of ptfe bearings reduces power losses and increases energy efficiency, while the wear-resistant bronze layer provides extended service life. Due to self-lubricating, the bearings require little maintenance. However, they can also be used with lubricants to prevent shaft/bearing seizing that can occur under boundary conditions.

Always self-lubricating & grease-free

Bronze oil-free bearing

  • The product is based on tin-phosphor bronze, with a sintered spherical bronze layer in the middle and a mixture of modified polytetrafluoroethylene (PTFE) and slide fibers layer rolled on the inside.

  • It has good self-lubrication, loss, low friction coefficient, and other properties, the product is used in metallurgical machinery, continuous casting rolling mill, cement grouting machinery, screw-type transporters, etc.

  • Copper-based oil-free bearings (non-standard sizes can be customized)
