PEL®

PEL bushings and sleeve bearings have an excellent resistance to wear and seizure thanks to the combination of a duplex surface treatment and a special surface topography.

This cross hatching topography provides large grease reservoirs in the loaded area and enables removal of abrasive particles.

These bushings are ideal for severe operating conditions: high pressure, abrasion, shocks and corrosion.

PEL LV bushings are an alternative with no cross hatching on the ID. They offer really good performances (wear and seizure resistance) under high static loads (low dynamic pressure) and by small oscillating movement.

Interval of lubrication up to 50 hours (depending on the working conditions), Excellent resistance to seizure and wear, Excellent distribution of the grease on all the friction. Well adapted for automatic greasing system and/or small oscillation movement

Mating Shaft:
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.
