PEL® BH bushings are machined bearings with excellent resistance to wear and seizure due to the combination of a duplex surface treatment and special grease reservoirs.
They are extremely used in harsh working conditions: high pressure, corrosion, abrasion, shocks. With these bearings the intervals of lubrication are considerably increased.
Due to recent developments PEL® BH2 bushings offer improved wear resistance.PEL® BH technology is also available on spherical plain bearing in case of angular misalignment or flexion in the joint.
See more detail about spherical plain bearing.

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.
