Liquid nitriding is a subcritical surface enhancement process with one of the longest track records of success of any case hardening technology.
PVD coatings involve the deposition of thin (2-10 microns; 0.0001" – 0.0004") films on the surface of tools and components.
PEL HP bushings have an excellent resistance to wear and seizure thanks to the combination of a duplex surface treatment and optimized surface topography.
They work very well with translation movements and are ideal for severe operating conditions: high pressure, abrasion, shocks and corrosion.
With these bearings lubrication intervals are increased leading to reduced maintenance.

For optimal performances of the joint, the surface roughness should be inferior to Ra 0.8 μm and the hardness should be superior to 56 HRC. For optimal performances, special shafts are available from HEF DURFERRIT: PEL ST, PEL STC.
