PTFE self-lubricating bushing – DU bushing

glacier bushes and du bushing manufacturers

DU bushing means Dry Unlubricated, and they are suitable for rotating, oscillating, and linear movements, whereas straight (cylindrical) bushings can accommodate radial loads only and flanged bushings can accommodate radial and axial loads in one direction.

The PTFE-based glacier bushes sliding surface permits smooth, low-friction operation without lubrication.

standard sizes of du bushing

PTFE/Pb mixture 0.01~0.03mm as a sliding layer provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.
Porous bronze 0.2~0.3mm provides Max. thermal conductivity away from the bearing surface also serves as a reservoir for the PTFE-lead mixture.
Low-carbon steel backing 0.7~2.3mm provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.
Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.
