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 in translation movement and are appropriated to works in severe working conditions: high pressure, abrasion, shocks and corrosion.
With these bearings the intervals of lubrication are increased.

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.
Interval of lubrication up to 250 hours (depending on the working conditions)
Excellent resistance to seizure and wear
Good distribution of the grease on all the friction surface
Attachment / grapples
